What effect does the size of an amino acid on the retention factor?
Anarel [89]

According to proteomic data analysis, the N-terminus residues highly influence the retention of amino acids due to their role in ion-pairing. Every amino acid has a retention coefficient factor depending on the N-terminus residues it contains. Therefore, the longer the amino acid the higher the likelihood of it having high N-terminus residues and consequent high retention co-efficient.

Which of the following processes includes all the others?
Vinvika [58]

Answer:

Passive transport.

Explanation:

The transport of molecules across the plasma membrane can occur by the two process- active transport and passive transport. No amount of energy is required during the active transport.

Passive transport includes the diffusion and osmosis. Both the diffusion and osmosis do not require energy and the molecules move down from the region of higher concentration towards the region of lower concentration. Small molecules, ions and proteins can go through the passive transport.

Thus, the correct answer is option (c).

atroni [7]

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.
