Answer:
The correct options are:
c. phenylalanine
f. tyrosine
Explanation:
The specificity of the pocket of chymotrypsin is for <em>aromatic aminoacids</em> o amino acids with <em>bulky hydrophobic chains</em>. From the list of amino acids, the aromatic amino acids are <em>phenylalanine</em> (with a phenyl group) and <em>tyrosine </em>(with a phenolic group).
From the rest, there are not amino acids with bulky hydrophobic side chains. Arginine has a 3-carbon side chain but it has a polar guanidino group, so it is not a bulky hydrophobic R-group. Alanine is hydrophobic but it is not bulky - it has only a methyl (-CH₃) group as R-group. Aspartate is not hydrophobic neither aromatic. Finally, glycine is very simple, it has only a -H as R-group.

The reticular activating system's main function is regulating arousal and sleep−wake transitions
Answer:
Isotonic
Explanation:
A solution that has same concentration os solutes inside and outside is called isotonic solution.As no concentration gradient is developed to induce the diffusion of large amount of water across the cell membrane rather water molecules freely diffuse in and outside the cell.So there is no gain and loss of water by the cell due to which the cell neither shrinks not swell
Answer:
Control environment is the most important procedures for getting good results.
Explanation:
The control environment for an experiment is the essential part for getting good results. In control environment, there is no or less chances of infestation from the external environment which can cause the results of the data more acceptable. So the scientists prefers laboratory for performing experiment as compared to outer environment. So in my opinion for getting better results, the control environment is the most necessary experimental procedure.
Yes, for getting better results I think there is a step that could have been added to the procedure is to follow the international standard procedures for taking the readings by the experimenter.
