So my guess is 66 unless there is more to the question
Glutamic acid is a hydrophilic amino acid. At physiological pH, it is negatively charged. Carboxylic acid group ( -COOH ) in its side chain is responsible for both, the hydrophilic nature as well as negative charge of the glutamic acid. Because of its hydrophilic nature it is found on the surface of protein facing aqueous solution i.e. it is an extrinsic amino acid.
Valine on the other hand is a hydrophobic amino acid. It is neutral at physiological pH. Valine has an aliphatic side chain which is responsible for both, it's hydrophobic nature as well as neutral charge. Since it is hydrophobic, it is found inside of protein molecules i.e. it is an intrinsic amino acid.
The amount of energy available from the organisms within a tropic level determine the carrying capacity of the next tropic level

Answer:
Option-C
Explanation:
The M phase of the cell cycle proceeds in the four phases: prophase followed by metaphase then anaphase, and telophase.
These sub-phases can be easily distinguished as the genetic material move in the cell in various form and the changes become characteristic of the subphases.
During metaphase, the chromosomes are aligned at the center of the cell or at the imaginary equatorial plate. Since it is mentioned that the drug shows its effect when the chromosomes are aligned at the equatorial plate therefore he is referring to the metaphase of the cycle.
Thus, metaphase is correct.
