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:
92 chromatids
Explanation:
During phosphate, the nuclear envelope of the cell (which is where the 92 chromatids are contained) begins to break down. The centrioles, which are the only present in animal cells, separate and each moves to an opposite end of the cell
Answer:
D) resource partitioning.
Explanation:
Resource partitioning explains how species that are similar (in this case the two-spot and the three-spot avenger beetles) use their resources together (coexist). They live in the same community and use the same resources, but they don't push one another to extinction through competition. They use the same limiting resource at different time and thus, compete less with one another.
