Epidermal dendritic (langerhans) cells function as part of the ______ response.

Biology
1 answer:
nexus9112 [7]3 years ago
5 0
A. Immune

Langerhans cells , also known as accessory cells, are antigen-presenting cells of the skin. It functions by processing antigen material and and present it on the cell surface to the T cells of the immune system. The cells process microbial agents to be fully functional antigen-presenting cells. It is similar to  blood monocytes.

Why do prokaryotes reproduce faster than eukaryotes?
JulijaS [17]
Prokaryotic cells reproduce asexually which makes it easier for them to multiply because all they have to do is split in half where as eukaryotic cells reproduce sexually so they have to find another cell to meet with in order to reproduce.

Memory cells may take the form of B cells. T cytotoxic cells. T helper cells. All of the choices are correct.
topjm [15]

Answer:

Having considered how an appropriate primary immune response is mounted to pathogens in both the peripheral lymphoid system and the mucosa-associated lymphoid tissues, we now turn to immunological memory, which is a feature of both compartments. Perhaps the most important consequence of an adaptive immune response is the establishment of a state of immunological memory. Immunological memory is the ability of the immune system to respond more rapidly and effectively to pathogens that have been encountered previously, and reflects the preexistence of a clonally expanded population of antigen-specific lymphocytes. Memory responses, which are called secondary, tertiary, and so on, depending on the number of exposures to antigen, also differ qualitatively from primary responses. This is particularly clear in the case of the antibody response, where the characteristics of antibodies produced in secondary and subsequent responses are distinct from those produced in the primary response to the same antigen. Memory T-cell responses have been harder to study, but can also be distinguished from the responses of naive or effector T cells. The principal focus of this section will be the altered character of memory responses, although we will also discuss emerging explanations of how immunological memory persists after exposure to antigen. A long-standing debate about whether specific memory is maintained by distinct populations of long-lived memory cells that can persist without residual antigen, or by lymphocytes that are under perpetual stimulation by residual antigen, appears to have been settled in favor of the former hypothesis.

In order to carry out the testcross, you should cross your original pea plant with another pea plant whose phenotype is ________
Makovka662 [10]
<span>My pea plant has an unknown genotype for flowers, whether it has two dominant traits for white flowers (WW) or one dominant and one recessive (Ww) leading to white flowers; therefore I am doing a testcross in order to determine the genotype of my pea plant. The best plant to do this with is one that has a phenotype of purple flowers (ww) - that is, it is homozygous for the recessive trait. If I use a homozygous recessive plant, I know exactly what its genotype is. I don't have to worry about whether it's got one or two dominant alleles; I know that at least half of my alleles are going to be the recessive w. This makes identifying the offspring's genotype very simple. If I find that the offspring have at least some purple flowers among them, I know that my original plant had to be Ww; that is it had to have one dominant and one recessive allele for the flower color gene. If, however, all of the offspring are white flowers, I know that my original pea plant had both dominant alleles (WW).</span>

An enzyme _____. is an organic catalyst is a inorganic catalyst can bind to nearly any molecule is a source of energy for enderg
Sidana [21]

An enzyme is an organic catalyst.

<h3>What is an enzyme?</h3>

Enzymes are proteins that help speed up metabolism or the chemical reactions in our bodies.

They build some substances and break others down.

All living things have enzymes. Our bodies naturally produce enzymes.

But enzymes are also in manufactured products and food.

Examples of specific enzymes:

Amylase: In the saliva, amylase helps change starches into sugars.

Maltase: This also occurs in the saliva, and breaks the sugar maltose into glucose.

Trypsin: These enzymes break proteins down into amino acids in the small intestine.
