Answer:
The HIV virus that causes AIDS kills T-cells. T-cells are responsible for fighting off infections. So someone with AIDS has a reduced number of T-cells and are unable to fight off infections that are harmless to other individuals.
explain how the mammalian skin perform it's role as a thermoregulatory
Answer:
The skin contains many blood capillaries and sweat glands ,the sweat glands secrete sweat when it is hot.when the sweat evaporates from the skin it cools the body.thermoregulation by the skin occurs through dilation and constriction of the blood vessels.when the bodies temperature raises,the blood vessels carry heat in the blood to the skin.the blood capillaries dilate become wider so that more heat can be lost to the environment.this is called vasodilation.when the outside temperature is low,the blood capillaries constrict become narrower so that less blood flows to the surface of the skin.therefore less heat is lost to the environment this is called vasoconstriction.
I hope this helps

One of the distinguishing characteristics of nervous tissue is how difficult it is to repair damage to nervous tissue. Explain factors limit neurogenesis in the CNS of adults, why is it so hard to repair a damaged nerve
Answer:
Inhibitory influences from neuroglia, and the absence of growth-stimulating cues.
Explanation:
Neurogenesis in adults is limited by Inhibitory influences from neuroglia, mainly from oligodendrocytes, and the absence of growth-stimulating cues that are present during fetal development. It is so hard to repair a damaged nerve because nerve cell like other cells can't divide and increase in number, they can't renew themselves. Due to no division, the nerve cells does not increase in number and therefore can't repair themselves.

ason Kimble's study of the Archaea in Snowy River in Fort Stanton Cave showed that Archaea play an important role in __________.
Answer:
Ecosystem.
Explanation:
Archaea play an important role in ecosystems with organisms that derive or produce energy from oxidation of methane. Many of Archaea are bacteria which are often a major source of methane in such environments and they can play a role as primary producers. Archaea is important for scientists because it has unique ecological roles and can also generate energy differently i.e. responsible for producing biological methane which no eukaryotes or bacteria can do that.

Answer:
Chitin.
Explanation:
The structure that is not a component of wall of sponges is Chitin. Their body comprise of calcareous or siliceous spicules or protein spongin fibres. Choanocytes are the distinctive cells located in the interior body walls of sponges. Sponges are similar to other animals in many characteristics such as they are multicellular, heterotrophic, lack cell walls and produce sperm cells in order to produce offspring sexually and also different from animals due to lack of tissues and organs.
You have a microorganism you know is both fastidious and which normally lives in human lungs. Which medium might this organism have the highest probability of growing on and why
Answer:
It is likely that this microorganism grows in enriched culture media.
Explanation:
As shown in the question above, the microorganism that lives in the lungs is extremely demanding. This means that this microorganism is very difficult to be cultivated in a culture medium, as it requires specific nutrients and in specific amounts to be able to develop. These microorganisms are called fastidious microorganisms and need an enriched culture medium to develop.
Enriched culture media are those that have a high range of nutrients in their composition. These culture media are highly nutritious and for this reason, they are the ideal environment for demanding microorganisms, as it can efficiently meet the needs of this organism.

What is the correct order of the levels of organization in animals from smallest to largest?
Answer:
Molecules, cells, tissue, organ, organ system, organism, population, community, ecosystem, and biosphere are in the correct order of the organization's levels.
Explanation:
Molecule: Atoms, the smallest unit of chemical elements are built up of molecules. You can find it in any matter, whether it lives or not. The most fundamental structures of biological creatures are molecules. Biochemistry and molecular biology are two biological fields focused on this level.
Cell: A cell is the basic unit of life. Two types of cells exist plant cells with a stiff cell wall consisting of cellulose molecules and animal cells with a flexible cell membrane. Cell biologists examine problems like metabolism and other structure and functional questions within and between cells.
Tissue: Tissue consists of cells working together to accomplish a goal. Some tissues include muscle, connective tissue, and neural tissue. Examples of biologists working at this level are histologists.
Organ: An organ is a tissue system that works at bigger scales together to perform specified work in the body of an animal. Brain, heart, and lungs are examples of organs. Anatomy is an example of a specialty in biology which concerns this level.
Organ system: An organ system is a group of bodies that work together to fulfill certain activities of the body. Air systems are used to inhale oxygen and release carbon dioxide in animals, for example, by the lungs, respiratory tract, and muscles. The function of the corpus when working jointly is studied by physiologists. Although physiologists can work at any level, they commonly address queries about organ systems.
Organism: An organism is an autonomous and recognized person. The organisms might be single-cell or multi-cell organisms consisting of organisms and organ systems, as well as bacteria, amiable, or creatures. An example of a multi-cellular organism is a human being.

Which answer option below describes the best way to increase the accuracy of a
confidence interval calculation?
The accuracy of a confidence interval calculation can be increased from 95% to 99%.
Thus, option C is correct.
What is confidence interval?A confidence interval contain a population parameter in a specified proportion of the time, which can be computed using the given confidence level from a limitless level of individual sample.
The proportion of the range consists of the true value of the factor that will be identical to the confidence level.
In most of the confidence interval examples, the confidence level chosen is 95%. and it can be raise up to 99%.
It cannot estimate the plausible values of the unknown parameter of the population.
Two types of confidence interval observed such as accuracy which is defined based on whether the confidence interval contains the true population parameter or not.
Secondly, the precision defined in terms of the width of a confidence interval.
Hence, option C is correct.

Complete the comparison of the metabolic pathways leading to thymine in DNA and thymine as a modified base in tRNA.
Thymine in DNA occurs as the result of thymidylate synthase creating _______________ , which then undergoes ____________ to ____________, then to __________, and incorporated into DNA by ___________.
Answer:
The question is incomplete, the complete question is as follow:
Thymine in DNA occurs as the result of thymidylate synthase creating _______, which then undergoes _______ to _______, then to _______, and incorporated into D N A by _______. Thymine in tRNA arises ________, by an S-adenosylmethionine-dependent _______ of a ______ residue in RNA.
Answer:
Thymine in DNA occurs as the result of thymidylate synthase creating dTMP, which then undergoes phosphorylation to dTDP, then to dTTP, and incorporated into DNA by DNA polymerase. Thymine in tRNA arises posttranslationally, by an S-adenosylmethionine-dependent methylation of a UMP residue in RNA.
Explanation:
Thymidylate synthase is a key enzyme that catalyzes the synthesis of 2′-deoxythymidine-5′-monophosphate (dTMP) from 2′-deoxyuridine-5′-monophosphate (dUMP). This enzyme catalyzes the addition of a phosphate group (phosphorylation) of dTMP in order to form thymidine 5'-diphosphate (dTDP). Once synthesized, dTMP can be metabolized to deoxythymidine triphosphate (dTTP), which is a precursor for DNA biosynthesis. On the other hand, transfer ribonucleic acid (tRNA) is methylated after the molecule is synthesized. The transfer of the methyl group is catalyzed by an S-adenosylmethionine–dependent methyltransferase that catalyzes the methylation of uridine monophosphate (UMP) using SAM (S-adenosylmethionine) as the methyl donor.

Below is an image of a nucleus before it divides via meiosis. The chromosomes shown in red are from the female parent, and the chromosomes
in blue are from the male parent. Predict the gametes that can be created from this organism and explain the reason these different gametes are
possible.
Answer:
I predict that the gametes will be unique from their parents.
Explanation:
I predict that the chromosomes will pair up, with each pair having a red chromosome and a blue chromosome, then they'll cross over and exchange similar genetic information with each other. I think this because variety is important for any species for survival.

Which is the main light-absorbing pigment for photosynthesis?
O carotene
O chlorophyll
O hemoglobin
O anthocyanin
Answer:
ChlorophyllExplanation:
Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.
Answer:
B) Chlorophyll
Explanation:
The chloroplasts, which contain the green pigment chlorophyll, are where photosynthesis takes place. Chlorophyll is the pigment that gives plants their distinctive color. It works by collecting the energy in the sunlight that strikes the plant. Because grass requires photosnthesis to create glucose, which is required for growth inside the grass, photosynthesis is critical to life on Earth. As a result, creatures that eat the grass get energy, and so on. As a result, photosynthesis is the mechanism through which energy is introduced into an environment.

Whose argument is stronger regarding the SAC curves and the LAC curve? A. The draftsman since the lowest point on each SAC curve will have a horizontal tangent line which only occurs at the lowest point on the LAC. B. Jacob Viner since the SAC curves can be adjusted slightly and still keep their U-shape in a way that makes their lowest points end up on the LAC curve. C. Jacob Viner since the long-run average cost curve must be composed of the lowest points on any individual short-run average cost curve. D. The draftsman since, while it is true that the points of tangency of the SAC curves with the LAC curve are at each SAC curve's minimum, it is impossible to illustrate it accurately.
NB: This is a business question, not biology.
Answer:
SAC (Short-run Average Cost) and LAC (Long-run Average Cost)
The stronger argument regarding the SAC (Short-run Average Cost) curves and the LAC (Long-run Average Cost) curves is:
A. The draftsman since the lowest point on each SAC curve will have a horizontal tangent line which only occurs at the lowest point on the LAC.
Explanation:
The costs of all factors of production become variable in the long run. But in the short-run, some costs are variable, and some are fixed. When the producer starts operating over the long run period, it can then operate without the constraints imposed by the presence of the fixed-cost factors. Therefore, in the long run, the average cost (LAC) is equal to the short-run average cost (SAC) because there is an unconstrained minimum average cost at all output levels.

Answer:
EeWw
Explanation:
This question involves two genes; one coding for earlobes and the other for hairline. According to the question, one parent is homzygous recessive for earlobe but homzygous dominant for hairline i.e. (eeWW) while the other parent is homzygous dominant for unattached earlobes but homzygous recessive for hairline i.e. (EEww).
The cross between the two parents is as follows: eeWW × EEww. The following gamete combination will be produced by each parent:
eeWW - eW, eW, eW, eW
EEww - Ew, Ew, Ew, Ew
Using these gametes in a punnet square, the following proportions of offsprings will likely be produced:
All EeWw offsprings
