Regarding epitopes for BCRs and/or for TCRs, indicate whether each statement below (a-e) is true. (5 pts) If the statement is only true for epitopes for BCRs--write (B) If the statement is only true for epitopes for TCRs--write (T) If the statement is true for epitopes for both BCRs and TCR--write (BT) If the statement is NOT true for either epitopes for BCRs or TCR--write (N) a. epitopes may consist of non-sequential amino acids b. epitopes are often from the interior of an antigen c. epitopes can be present in immunogens d. epitope binding to the antigen receptor obeys the 12/23 rule e. multiple identical epitopes may be present in a single antigen

a-B

b-N

c-BT

d-BT

e-BT

Explanation:

a. epitopes may consist of non-sequential amino acids >  B (is only true for epitopes for BCRs)

b. epitopes are often from the interior of an antigen > N (IS ONLY TRUE FOR EPITOPES FOR TCR)

c. epitopes can be present in immunogens  > BT (True for both TCR and BCRs )

d. epitope binding to the antigen receptor obeys the 12/23 rule > BT (True for both TCR and BCRs )

e. multiple identical epitopes may be present in a single antigen > BT (True for both TCR and BCRs )

answer; (phospholipid);

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
