_____________8. area where weblike pre-keratin filaments first appear.
_____________9. deep layer of the dermis
_____________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. The Epidermis is made up of five cell layers, which have different functions: Stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
i. dermis as a whole: composed of conjunctive dense tissue that provides support, resistance, and thickness to the skin.

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.
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.

Which of these statements best explains why the rainfall in volcanic regions increases after a volcanic eruption?
The volcano releases particles which help form water droplets.
The volcano releases heat causing clouds to form.
The molten lava from the volcano helps form water droplets.
The increase in fertility of soil around the volcano helps produce rain.
Answer:
The volcano help releases particles which help rain to fall.
Explanation:
Volcano is a form of opening in the Earth crust that make particles that are warmer in it surronding such as magma, hot lava, volcanic ashes to escape from beneath it. Volcano happen as a result of magma rising above Earth surface making the bubbles to spring forth. There is rain, lightning and thunder during volcanic eruptions.
Rainfall near a volcanic region increases after volcanic eruptions because all the ash particles that rises to the atmosphere attract and collect water droplets, thereby causing abundant of rainfall wen the water droplets are released.

What brings greater concentrations of dissolved nutrients to the ocean surface?
Answer: Upwelling
Explanation:
Upwelling is a process of movement of dense, cold and nutrient rich water from the bottom of the ocean to the surface layers due to wind currents. This process replaces the warm and nutrient deficient water from the surface.
This process is useful for the growth of phytoplanktons and other sea plants growing in the surface layer of oceanic water.
when the community climax in an ecosystem has only a single type of climax, the development of the climax community is controlled by ___ of that region.
a) the climate
b) the life forms
c) the soil texture
d) the pioneer community
Answer:
A.
Explanation:
because the climax community is composed of species beat adopted to average conditions in that area
When the community climax in an ecosystem has only a single type of climax, the development of the climax community is controlled by the climate of that region. Option A is correct.
The climate of a region is the most important factor that controls the development of a climax community. The climate determines the temperature, precipitation, and other abiotic factors that influence the growth and survival of plants and animals.
In a region with a single type of climax community, the climate is relatively uniform and there is little variation in the abiotic factors. This means that the same species of plants and animals will be able to survive and thrive in the region, regardless of the specific location. The life forms, soil texture, and pioneer community can all influence the development of a climax community, but they are not as important as the climate. Option A is correct.

. 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
10. In the water cycle, liquid changes to gas by

Answer:
evaporation
Explanation:
when the liquid heated for a long time it removes steam in form of gases
In the water cycle, liquid changes to gas by evaporation, which is in Option C. The water cycle, also known as the hydrological cycle, describes how water circulates through the Earth's ecosystems.
What is the water cycle?The water cycle involves a series of processes that include evaporation, condensation, precipitation, and infiltration. Evaporation is the process by which water changes from a liquid state to a gaseous state, such as water vapor. This occurs when energy (in the form of heat) is absorbed by the water, causing the water molecules to move faster and break free from their bonds to form a gas. After water evaporates, it can undergo condensation, which is the process by which water vapor changes back into liquid water.
Hence, in the water cycle, liquid changes to gas by evaporation, which is Option C.

Answer:
This question lack options, options are:
A. Mutation
B. Evolution
C. Heredity
D. Reproduction
The correct answer is B.
Explanation:
Evolution is essentially a process of genetic change over time, that is, it is the result of accumulated changes in the composition of the gene pool. Variation is the raw material of evolution. Without genetic variation, evolution is not possible. The ultimate source of all genetic variation is mutation. A mutation is a stable and inheritable change in genetic material. Mutations alter the DNA sequence and therefore introduce new variants. Many of these variants are usually eliminated, but occasionally some of these variants can be successful and incorporated into all individuals of the species. Mutation is a factor that increases genetic diversity. This is how evolution explains the origin of various life forms as a result of changes in their genetic load. The inheritance of these variations through offspring of parents who carry the variation, although the genetic endowment of a single organism is the same throughout life, the genetic makeup of a species, understood as a whole (genetic background), changes throughout from many periods of life. Mutations and variability, the product of natural DNA recombination, provide diversity in the genetic material of a species.

Explain how these changes would impact BPG binding to deoxyhemoglobin along with the impact it would have on oxygen transport with hemoglobin
Answer:
It affects the oxygenation of the tissues in a negative way, that is, causing tissue hypoxias.
Explanation:
What will happen is that BPG, having a different relationship with deoxyhemoglobin, hemoglobin will not give oxygen to organs or tissues during glycolysis at times when the sympathetic nervous system is activated or even in the maintenance of physiological tissue vitality, therefore it will trigger a drop in the partial pressure of the gas both in the blood and in the tissues since they will be retained in the hemoglobin structure without being able to release it.

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.

1/4 = 4/16 purple
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.

Explanation:
The onion root tip is the growing part of the onion and many cells in it undergo mitosis. In the lab, it is prepared in a way that the cells become flat on the microscope slide so that you can observed them well.
In the cell cycle, most of the onions root tip cells are in interphase, they spend most of their life in interphase. In interphase, there is no observable changes in the celks, the cells keep on growing and the nucleus is been duplicated. This is because most of the onion root cells spend most of their time reproducing and growing in the interphase stage. During the interphase, the cells can still be seen in dark spots because the nucleus is still present and prophase has not started yet.
