Answer:

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.

Answer:

c. Amino acids          

Explanation:

             BBB stands for the blood brain barrier. The proper functioning of the brain is meant by the amino acids. Amino acids are most necessary for  production of proteins which are essential for the working of any cell.

           In general antibodies and large polysaccharides like starch are too large and are not able to cross the blood-brain barrier. Whereas urea does not have specialized proteins and therefore they cannot enter the brain.

Hence the correct option is (c).

Lemur [1.5K]

Answer: B

Explanation:

The question wants to know what the expression is directly dependent on.

The sequence of genetic expression goes like this:

  DNA -> RNA -> protein

If we want to know the root cause of expression, we must look at the DNA, not the RNA or protein, because DNA determines the RNA and protein expression.

 

The  Shape of subunits in DNA -> Sequence of bases coded for by the ribosome with RNA -> Arrangement of amino acids in the protein synthesized.

Why not C: Number of chromosomes present isn't a factor, because most humans, barring those with a genetic disorder, have 23.
