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.
The male parent is ww, and the female parent is rw. If you put these in a pungent square the results are rw, rw, ww, ww. This means 50% of their offspring would have red eyes.
Pair-bonding in a population of prairie voles can be prevented by . B) administering a drug that inhibits the brain receptor for vasopressin in the central nervous system (CNS) of males
<h3>
what is pair bonding?</h3>
Pair bonding is an evolutionary feature that may be important for reproduction as well as individual and species survival.
The proximate processes underlying many types of good social behaviours, such as pair bonding and maternal-infant behaviour, are shared by brain and endocrine systems.
The brain systems that rely on peptides, such as oxytocin, vasopressin, opioids, CRH, and associated hormones, are at the heart of pair bonding.
Neuropeptides also help to integrate the autonomic and endocrine effects of pleasant social encounters with behavioural states that promote social bond creation and maintenance.

<em><u>Question</u></em>: If you wanted to look at cell wall which type of cell would you observe?
<em><u>Answer</u></em> - ℓєαƒ ¢єℓℓ
<em><u>Explanation</u></em>:
Only plant cells have cell wall. Animal cells do not have a cell wall.
I believe the answer lies in the function and adaptive physiology towards the two anatomical different nerves. This correlates to their response and reaction to the present stimuli.
