Which of the following molecules is/are most likely to have selective proteins in the bbb to facilitate its passage into the brain? a. antibodiesb. starchc. amino acidsd. urea

The correct answer is option - C amino acids.

Explanation:

The blood brain barrier or BBB is border that separates extracellular fluid in the central nervous system (CNS) and the blood that is circulating from the brain.

This barrier is allows the passage by facilitate diffusion (passive diffusion) and through the selective proteins of molecules such as glucose, amino acids that are essential for the neural function.

Thus, the correct answer is -  amino acids.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
