Complete this sentence. The CNS communicates with the body proper through ________. View Available Hint(s) Complete this sentence. The CNS communicates with the body proper through ________. some cranial nerves, some spinal nerves, and some additional nerves that were mentioned but not discussed in the tutorial the spinal nerves but not specifically through the cranial nerves the cranial nerves but not specifically through the spinal nerves some (but not all) of the cranial nerves and some (but not all) of the spinal nerves the cranial nerves and the spinal nerves
Answer:
The correct answer is - The cranial nerves and the spinal nerves.
Explanation:
The central nervous system or CNS includes the brain and the spinal cord of the nervous system where it takes sensory information, integrates, and responds accordingly. The spinal cord acts as a conduit for signals between the brain and the rest of the body.
Spinal nerves and crania; both play an essential role in taking sensory information and respond accordingly. Spinal nerves are nerves that help in sending motor, sensory, and autonomic signals between the CNS and the body. The cranial nerves supply information to the CNS and then from the CNS to the body.
Thus, the correct answer is - The cranial nerves and the spinal nerves.
Given the behavior and ecology of this insect, what are some factors that could cause the incidence of Chagas disease to increase in Central and South America in areas like the banana plantation, and why
Answer and Explanation:
There are many physical elements such as temperature, precipitation, humidity, altitude, vegetation, among others, that influence the presence of the insects that transmit the Chagas diseases. Its transmission seems to be enhanced by other social elements, such as the deficiency in basic services, lack of planning, the socio-economical conditions, cultural conditions. Altogether, these factors intervene in the presence of the Chagas disease, a systemic infection caused by the protozoa Trypanosoma cruzi. This protozoan is hosted by different wild and domestic mammals, transmitted to the human by hematophagous insects. The transmission occurs through dejections deposited on skin or mucose during or after the feeding process.
Different rural areas in Central and South America are characterized by a mountain relief (temperatures between 15 and 30ºC - relative humidity between 50 and 90%), as well as by a plane relief associated with alluvial plain (temperature between 20 and 35ºC - media relative humidity of 75%). Vegetation in the mountain area provides a natural habitat to the triatomines, the insects that transmit the Chagas disease.
Constant deforestation in mountains, soil move, the cutting down, firing, have destroyed the natural habitat of the insects, becomming the cause of their arrival to populated centers. As their environment is destroyed, insects migrate to new areas and find refuge in precarious houses that surround the affected areas. Most of these houses have clay walls, a roof made of branches, and no floor. People that live in these conditions do not have economic resources. Indexes of infestation in these houses are high due to the material used for their construction. Insects tend to establish near a source of food, such as domestic animals or even humans. It is also common that these houses have chicken coops and farmyards that also offer good conditions for the insects to live in.
Economic activities are important variables to consider, as these define the way of living in a population.
Agriculture activities are performed with no control or planning. People deforest to plant, getting in contact with the insects' natural habitat, producing environmental changes, and getting in touch with them, enhancing the risks of being infected and of transportin the insects.

The punnets square shows a text cross of mice that are heterozygous for both traits what will the offspring be fill in the white boxes of the punnets square with all the possible offspring genotypes
Answer:
Explanation:
Dominant allele are allele that finds expression the offspring physical expression while recessive allele are alleles that are not expressed in the offspring phenotype.
g A variable trait in corn is the presence or absence of knobs at particular sites on some chromosomes. The allele present on each chromosome determines whether or not that chromosome has a knob. Suppose that one member of each of two pairs of homologs in a corn plant has a knob. If this plant is crossed with a knobless plant, what percentage of the offspring is expected to have only knobless chromosomes
Answer:
50%
Explanation:
The allele present on each chromosome determines whether or not that chromosome has a knob. Suppose that one member of each of two pairs of homologs in a corn plant has a knob.
This means that on a chromosome with two chromatids, the allele present on one chromatid causes the chromatid to possess knob while the other does not making the plant an heterozygous...
If this plant is crossed with a knobless plant, one whose Chromebook is without knobs, we have
II x II
II - 50% with a knobbed chromatid
II - 50% with only knobless chromosomes.
The first to the left is knobbed, thus the percentage of offspring expected to have only knobless chromosomes would be 50%.
Assuming a diallelic gene and complete dominance, the percentage of the offspring that is expected to have only knobless chromosomes is 50%

_____________10. layer that secretes a glycolipid that prevents water loss from the skin
Answer and Explanation:
b. stratum corneum: 5. layer including scalelike dead cells, full of keratin, that constantly slough off.
The most superficial epidermal layer conformed of squamous, plane, thin cells with keratin in their cytoplasm, that are continuously released. These cells are replaced by new cells that have the same destiny.
d. stratum lucidum
: 1. layer of translucent cells in thick skin containing dead keratinocytes
Also known as the transparent layer, is only located in the thicker parts of the skin, such as the hands´ palms and the feets´ soles. This layer is so thin that the cells´ edges and some ties their nucleus can not be identified. Keratinocytes are diaphanous and are grouped together. They lack a nucleus and the cytoplasm is filled with a gelatinous substance, eleidin, which will transform into keratin.
b. stratum corneum and d. stratum lucidum 2. two layers containing dead cells.
c. stratum granulosum: 6. layer named for the numerous granules present.
These layer cells contain granules filled with keratohyalin that is needed for keratin production. These cells are arranged in two to four layers, and they begin to degenerate. This is why they show high lysosomes enzymes concentration. This is also the layer where it begins keratinization.
e. stratum spinosum: 10. layer that secretes a glycolipid that prevents water loss from the skin.
8 to 10 irregular cell layers. These cells are rich in DNA necessary for proteinic synthesis that ends in keratin production, and Langerhans cells that belong to the immunity system. This stratus is also known as "Malpigio stratum". It also produces a glycoprotein that helps to prevent water loss.
a. stratum basale 4. epidermal layer exhibiting the most rapid cell division.
7. location of melanocytes and tactile epithelial cells.
Stratum basale is the innermost germinative, single, basal layer of the epidermis composed of basal cuboidal-shaped cells. These cells are the precursor of keratinocytes, this is why this layer is also called germinativum. In this basal layer, there are also Merkel cells as well as melanocytes. The former associated with nerve fibers, transmit part of the touch, and the latter, form the pigment responsible for skin coloring and tanning, melanin.
f. papillary layer: 3. dermal layer responsible for fingerprints.
This stratum is a thin superior layer in the dermis. It has conjunctive tissues and blood vessels that nourish the skin and helps to control the temperature. It´s surface forms papilla that increases the mechanical union between dermis and epidermis.
g. reticular layer: 9. deep layer of the dermis
The inner and thicker layer of the dermis. It is characterized by it´s thick, irregular bundles of collagen fibers and elastic fibers. These are not randomly oriented but forming the regular skin tightening lines known as Langer lines.
h. epidermis as a whole: 7. location of melanocytes and tactile epithelial cells.
Composed of a plane stratified keratinized epithelium that constantly grows and maintains a normal thickness by the process of peeling.

What would be an appropriate evolutionary explanation of the fact that the ordering of some homeotic genes (e.g., Hox genes) on vertebrate chromosomes parallels the ordering of homeotic genes on fruit fly chromosomes? Group of answer choices
Answer:
The correct answer is "The similar ordering of homeotic genes in animals, both vertebrate and insect, is due to ancient homology".
Explanation:
The missing options of this question are
a. Homeotic genes show that insects and vertebrates are closer relatives than the traditional classification system indicates.
b. The similar ordering of homeotic genes in animals, both vertebrate and insect, is due to ancient homology.
c. The similarity is a coincidence, not documented in other invertebrates and largely a result of random mutations.
d. Homeotic genes of different animal lineages might be ordered in a similar fashion, yet their sequences are completely different.
The correct answer is option b. "The similar ordering of homeotic genes in animals, both vertebrate and insect, is due to ancient homology".
Ancient homology, is a concept proposed by Charles Darwin that explains that species have homologous structures because they share a common ancestor. This explains as well why the ordering of some homeotic genes on vertebrate chromosomes parallels the ordering of homeotic genes on fruit fly chromosomes. Even though vertebrates are not as evolutionary close to fruit fly as other species, they share an ancient common ancestor as well. This same phenomena explains other homologies seeing in species, such as the adaptive mimetic diversity across butterflies.

Two true-breeding white strains of the plant Illegitimati noncarborundum were mated, and the F1 progeny were all white. When the F1 plants were allowed to self-fertilize, 126 white-flowered and 33 purple-flowered F2 plants grew. a. Using the ratio of these offspring, determine how flower color is inherited? b. Define allele symbols.. Indicate (using these symbols) the genotypic classes and the corresponding phenotypic ratios of the F2. c. A white F2 plant is a allowed to self-fertilize. Of the progeny ¾ are white-flowered, and ¼ are purple-flowered. What is the genotype of the white F2 plant? Briefly explain how you determined your answer.
Answer and Explanation:
Suppression: refers to an allele of a gene that can annul the expression of the other gene. The suppressor gene might be associated with its own particular phenotype (such as color) or it might not have any detectable effect other than suppressing the other gene expression.
Available data:
Two true-breeding white strains of the plant Illegitimati noncarborundum were mated the F1 progeny were all white the F1 plants were allowed to self-fertilize 126 white-flowered and 33 purple-flowered F2 plants grew.a. Using the ratio of these offspring, determine how flower color is inherited?
There are two genes involved in the color expression, we might define them as C gene for color, and W gene for suppression of the color. So, W inhibits the expression of C. The dominant C allele expresses purple, while the recessive allele does not express color.
As there are two genes interacting, there are 16 possible offspring produced. So, if the total individuals in the F2 are 159 (126 + 33), then:
159 individuals in the F2 ------------ 100% progeny ---- 16
126 white-flowered individuals------79.25% -----------12.68
33 purple-flowered individuals -----3.32 % ------------ 3.32
These proportions approximate to the proportion 13:3, corresponding to the genetic interaction "suppression".
b. Define allele symbols. Indicate (using these symbols) the genotypic classes and the corresponding phenotypic ratios of the F2.
As we mentioned before, the proposed symbols for these genes are C for the color gene and W for the suppressor gene. The dominant allele C expresses purple, while the recessive allele c does not express any color. W allele inhibits C, and w allele does not inhibit c.

To get the proportion 3:1 we should self-fertilize and individual that is heterozygous for one of the genes and homozygote for the other gene. As we have 1/4 of purple-flowered plants, we can assume that there must be present the dominant allele C for purple color.

Answer:
The macromolecules; protein helps to gain muscle, fat helps provide stored energy for longer period, carbohydrates provide immediate energy.
Explanation:
Proteins are the macromolecules that help on the muscle building and storage. Bodybuilders utilize proteins to build their body and muscle protein. Protein has equal energy value as carbohydrates.
Fat help in providing energy when there is no carbohydrate provided energy to utilize. In the winters some animals hibernate they utilize the fat provided energy during the hibernation period.
Carbohydrate gives energy immediately for the cellular process and also help athletes to provide energy immediately. Runners drink carbohydrates based drinks to get energy before the race.
Which statement about venation is INCORRECT?
Some flowering plants have leaves that lack venation even though the stems and roots have vascular bundles.
Venation is important for delivering water to leaf cells and taking sugars to the stem.
Venation refers to arrangement of the veins within a leaf.
Venation patterns include pinnate, palmate and dichotomous.
In general, monocots exhibit parallel venation.
Answer:
Some flowering plants have leaves that lack venation even though the stems and roots have vascular bundles.
Explanation:
Venation refers to the arrangement of the veins in the leaf of a plant which are involved in the transport of material in the plants.
The xylem present in leaves transports water to the leaf whereas phloem transports sugar from the leaves to different parts of the plants. In angiosperms, no plants are known whose leaves lack the veins but stem and root possess the vascular bundles.
Monocot is characterised by their parallel veins whereas dicots possess reticulate veins. Also, the compound leaves possess one of the three types of venation that are palmate, pinnate and dichotomous.
Since no angiosperm posses, veinless leaves, therefore, is the correct answer.
the “good genes hypothesis” proposes that people with physical qualities like averageness, symmetry, sex prototypicality, and youthfulness are more attractive because they are better-quality mates. the “good genes hypothesis” is from which approach to psychology?: 1) evolutionary 2) psychodynamic 3) cognitive 4) biological
The correct answer is 1) Evolutionary
Explanation:
The "good genes hypothesis" argues traits of the opposite sex that are considered as positive or attractive reflect evolutionary traits and therefore are indicators of a better-quality mate. Indeed, this theory argues attraction is connected to better chances of survival or better chances to reproduce. This belongs to the evolutionary approach in psychology because these "attractive" traits are the result of evolution because only the "fittest" individuals reproduce and their genes prevail over time.

You inject an antibody against the protein tubulin into a living animal cell. After the injection, the cell begins mitosis, but the chromosomes do not become attached to the spindle; in fact, there is no spindle. The contractile ring does, however, form. What do these results mean?
Answer:
The mitotic spindle was “ blocked ” by the action of the antibodies that bind to tubulin.
Explanation:
The tubulin heterodimers consist of α- or β-tubulin structures that form the microtubules, which represent the cytoskeletal of eukaryotic cells. During mitosis, the microtubules are arranged in order to form the mitotic spindle, this structure is critical for the segregation of homologous chromosomes during Anaphase.
Interphase microtubules are required for attaching chromosomes in the middle of the cell during its division, thereby it is expected that the antibodies bind to these microtubules during this process.
The contractile ring is formed by approx. 20 actin filaments that encircle the middle of dividing cells, thereby it is expected that these antibodies are specific of tubulin heterodimers.
Fur color in mice is affected by a single gene. The gene for fur color has two alleles: B that causes dark brown fur, and b that causes light brown fur. In a mouse with dark brown fur, the genotype could be BB or:_________
Answer:
The genotype could be BB or Bb
Explanation:
The genotype could be Bb which means it has heterozygous alleles.
The B which is allele for dark brown fur is dorminant and b for light brown is recessive. In this case, the dorminant allele masked the effect of the recessive allele b which make the dorminant allele B to be expressed phenotypically.
. g Determine the number of moles in 0.05 µg of a 300 bp insert DNA. There are 660 g/mol-bp. What is the molar ratio of insert to vector if you have 10 ng of vector that is 2686 bp?
Answer:
a. 2.4 x 10^-24 mol
b. 5.4 x 10^4
Explanation:
a. Mass of DNA (of 0.05µg)= 0.05µg x number of base pairs x 650Da
=0.05x300x650Da
(1 Da=1.67x10-24g)
=9750 x 1.67 x 10^-24
=16282.5 x 10^-19µg =1.62 x10^-21 g
No. of moles of insert DNA=mass of DNA(in g)/mass of one mole in g/mol
=1.6 x 10^-21g/660 g/mol
=2.4 x 10^-24 mol
Hence, moles of the insert DNA is calculated as 2.4 x 10^-24
b.
First of all, let us determine number of moles of vector to calculate the molar ratio.
No. of moles of vector=10 x 10^-9 x 2686 x 650 x 1.67 x 10-24/660
=2.68x6.5x1.67x10-27/660
=4.4 x 10^-29 mol
Molar ratio of insert to vector=2.4 x 10^-24/4.4x10^-29
=5.4 x 10^4
So, the molar ratio of the vector and insert as per the data is calculated as 5.4 x 10^4

Explain what the impact of mutations in myosin that disrupt ATP binding would have on the power stroke during muscle contraction. and hydrolysis Skeletal muscle arrangement, ATP binding and correct muscle contractions
Answer:
These cells will be atrophied because muscle contractions can't occur.
Explanation:
In muscle cells, ATP binding causes a conformational change in the structure of myosin, thereby these filaments move to a high-energy configuration. The muscle contraction is caused when this high energy state is amplified in the actin filaments that bind to myosin, in a process dependent on the ATP hydrolysis. The myosin-actin cycle is repeated by binding another ATP molecule on the myosin head, producing the contraction of muscle cells.
Which of the following statements is true?A. An isolated system cannot exchange either matter or energy with its surroundings. B. Organisms are open systems when they are out of their habitats. C. Organisms are isolated systems because they have their own machineries in the cells to supply all the matter and energy they need. D. Open systems are called as such because they do not absorb energy, but just openly release the energy to their surroundings.

An isolated system can NOT exchange energy or matter with it's surroundings. This is why it is isolated.
After getting their results in, a group of scientists went back and looked at their study. As planned, their experiment consisted of three groups. The first group received a new medicine at a normal dose, the second group received the medicine at half the dose, and the third group received the medicine at twice the dose. Which of the following best describes what went wrong with the scientists’ study?
Answer:
Their experimental design lacks control group
Explanation:
Based on what I read, the scientists don't have a control group as one of the main groups thus they cannot, in scientific sense, say that the medicine is better or worse. You always need a control group receiving no intervention because then we can compare groups and assess the effectiveness of that intervention (in our case if we had control group vs people who received the medicine, we could see if the people who received the medicine had improved condition etc when compared to participants who did not receive anything)
There is no control group in their experimental design. According to what I've read, the scientists don't have a control group as one of the primary groups. Thus, option C is correct.
What is control group?To determine if the treatment is better or worse in a formal scientific sense. You should always have a control group that does not receive any treatment because this allows us.
To compare the groups and evaluate the effectiveness of the intervention. In our case, if we had a control group and participants who did not receive any treatment, we could see if those participants had better health overall.
By focusing on the impact of a single independent variable, a cause-and-effect link can be established.
The independent variable is altered in the treatment group while being held constant in the control group by researchers. The findings of these groups are then compared.
Therefore, no control group in their experimental design.

Answer:
Explanation:
The correct order of above question is -
1. Glucose
2. Fructose - 1,6 - biphosphate
3. Glyceraldehyde - 3 - phosphate
4. Pyruvate
5. Citric acid
6. Succinyl co- A
Explanation - These all are the step of carbohydrate metabolism in a cell. The carbohydrate is catabolise and successively into smaller forms.
First four steps show the glycolysis process in which by use of ATP glucose molecule breakdown into simpler one.
Last two steps show the kerb's cycle in which citric acid (six carbon compound) is converted into succinyl co - A ( four carbon compound) .
Why do processes and activities suddenly change the global temperature?
Answer:
hey mate here is your answer
Answer:
Earth's temperature depends on the balance between energy entering and leaving the planet’s system. When incoming energy from the sun is absorbed by the Earth system, Earth warms. When the sun’s energy is reflected back into space, Earth avoids warming. When absorbed energy is released back into space, Earth cools. Many factors, both natural and human, can cause changes in Earth’s energy balance, including:
Explanation:
Variations in the sun's energy reaching Earth
Changes in the reflectivity of Earth’s atmosphere and surface
Changes in the greenhouse effect, which affects the amount of heat retained by Earth’s atmosphere
