Explanation:
Answer:
Helper T cells are arguably the most important cells in adaptive immunity, as they are required for almost all adaptive immune responses. They not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells.
Explanation:
Helper T cells become activated when they are presented with peptide antigens by MHC class II molecules, which are expressed on the surface of antigen-presenting cells (APCs). Once activated, they divide rapidly and secrete cytokines that regulate or assist the immune response.
Answer:
100%
Explanation:
In this problem, we have one gene (pea color) with two possible alleles (green and yellow).
Green is dominant over yellow, so the possible genotypes and phenotypes are:
- GG or Gg = green pea pods
- gg = yellow pea pods.
If an individual is true breeding it is homozygous for all genes under study.
The cross between true breeding plants is:
<h3>GG x gg</h3><h3 />
The green parent (GG) can only produce <em>G </em>gametes; the yellow parent (gg) can only produce<em> g</em> gametes. 100% of the offspring will have the genotype Gg (green).
D, i believe it says it requires a bigger beak for crushing up seeds.
