Answer:
TCR
Explanation:
Helper T cells are the CD4T cells that are present in the inactive form. These cells have receptors for antigens on their surface. These antigen receptors are called T-cell receptors (TCRs). The function of TCR is to recognize and bind to specific foreign antigen fragments that are presented in antigen–MHC complexes. Different helper T cells have their unique TCRs to recognize a specific antigen–MHC complex. The CD4 proteins of helper T cells also interact with the MHC antigens and help maintain the TCR–MHC coupling.
Answer:
C
Explanation:
Looking at each embryo at the begining you can tell they are very similar, in fact its almost impossible to tell the difference. this tells us that they have a common ancestor because the orignal cells of the embryos are so similar
Answer:
Lower interest rates.
Explanation:
if a stock market crashes, the interest rates will also be lowered because they have a direct relationship between stock market and interest rates. When the stock market performs very good, the interest rates will be higher while on the other hand, if a stock market crashes, the interest rates will be lower so we can conclude that the interest rates will be lower if stock market crashes.
Answer:
white eyes and hairy body
Explanation:
Based on the scenario being described within the question it can be said that the allele combination that has the greater map distance would be white eyes and hairy body
. This is mainly due to the fact that this combination have four map units between them, when compared to the other same chromosome combinations which, the next runner up would be red eyes and normal body with two-units between them.
