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.

All cells are similar in composition and metabolic activities.
Answer: 1/4 (4 out of 16 offsprings express one of the two dominant alleles)
Explanation:
The dominant alleles are A and B
At the end of the cross AaBb x AaBb, 16 offsprings would result. They are as follows: AABB, AABb, AaBB, AaBb
AABb, AAbb, AaBb, AABB,
AaBB, AaBb, aaBB, aaBb,
AaBb, Aabb, aaBb, aabb.
Of all, only 4 offsprings (aaBb, aaBB, AAbb, Aabb) expresses one of the A or B. so 4/16 = 1/4
Crosscutting concepts have application across all domains of science. As such, they are a way of linking the different domains of science. They include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.
