which statement describes abiotic factors in an environment ?
What type of enzyme can activate another enzyme by adding a phosphate from ATP?
Answer:
Here my answer goes.......
Explanation:
In biochemistry, a kinase is an enzyme that catalyzes the transfer of phosphate groups from high-energy, phosphate-donating molecules to specific substrates. This process is known as phosphorylation, where the substrate gains a phosphate group and the high-energy ATP molecule donates a phosphate group.

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.
"Discuss three factors that affect your daily food choices. For each factor with a negative outcome, suggest at least one change you could make in your daily behavior that would turn that negative outcome to a positive outcome.
Answer:
Three factors that affect my daily food choices include:
1. Taste
2. Length of time for preparation
3. Method of preparation.
Explanation:
When making choices for food, I tend to take several factors into consideration. Some of these factors include;
1. The taste of the food: If the food tastes good and is not too spicy I am more inclined to choose such food.
2. Length of time for preparation: Especially on stressful days, I tend to consider the length of time required to prepare a healthy meal. If it takes so much time I am more inclined to eat fast food which is not a good choice.
To change this negative outcome, I hope to plan my affairs for the day and prepare healthy meals beforehand, which could be stored in the refrigerator and reheated when I need it.3. Method of Preparation: Some foods require paying attention to details. For example, food that uses up, a lot of vegetables would require thorough washing to prevent particles in the food. Busy days also get me exhausted with no strength to pay attention to these protocols.
To turn this around, I hope to employ the help of a family member to make the process easier. I also hope to process most of my ingredients and keep them ready for use so that I would not have to do a lot of processing while cooking.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.

A species of spruce tree occupies the same niche at the mouth of a river that a species of pine tree occupies further upstream. One year, several pinecones fall into the river and are carried to the mouth, where they take root and grow amongst the spruce trees. What will be the most likely result of this occurrence
Answer:
The correct option is: "Either the pine trees or the spruce trees will eventually evolve into a new species."
Explanation:
There will be a competition between spruce trees and pine trees for nutrition and other resources from the environment to grow and spread since they are now occupying the same niche. Overtime, one specie will outlive the other by evolving into a specie that gives it an advantage over the other.

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.

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%

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.

. 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

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.

Why do you think these groups have a high risk of osteoporosis
Answer:
lack or low calcium level
Explanation:
when a person has a low calcium intake, these people are susceptible to having osteoporosis as their bodies would be lacking of much needed calcium.
Low calcium intake increases osteoporosis risk. Lifelong calcium deficiency causes osteoporosis. Low calcium consumption causes bone loss, early bone loss, and fractures.
What is osteoporosis?Osteoporosis is a disorder that causes bones to become brittle and more prone to breaking, which increases the risk of fractures. It manifests itself gradually over the course of several years, but the condition is typically not recognized as a problem until a bone breaks as a result of a fall or a sudden impact. A broken wrist is the type of injury that occurs most frequently in people who have osteoporosis.
People who consume inadequate amounts of calcium are at increased risk for developing osteoporosis. The deficiency of calcium over a lifetime is one of the factors that can contribute to the development of osteoporosis. A diet deficient in calcium has been linked to decreased bone density, an accelerated rate of bone loss, and an increased risk of fractures.

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.
