Suppose that a glutamine residue in the active site of an enzyme was mutated to alanine. As expected, the alanine mutant was ina
likoan [24]

Answer:

A to N

Explanation:

Glutamine is an amino acid with a polar, uncharged side chain. The mutation to alanine, an amino acid with a non-polar side chain, completely affects the enzymatic activity. This makes sense considering the difference in the nature of both amino acids.

To restore the wild-type level of activity the alanine would have to mutate to another polar uncharged amino acid. Among the given options, only Asparagine (N) has a similar chemistry to Glutamine.

Without a cuticle, a plant _____.
kolbaska11 [484]
The answer is A. The cuticle is a protective film that is non cellular covering the outer cell layer (epidermis) of green, aerial parts of plants. Cuticles protect plants against drying (desiccation), UV radiation, and various kinds of physical, chemical and (micro)biological agents. The cuticle also provides some support. Actually the cuticle which protects the underlying tissues has basically the same function as our own skin. In several groups of plants, cuticles are very resistant. Only few groups do not generally have highly resistant cuticles e.g. ferns and lycopods.

lora16 [44]

Answer:

C) Water will move out of the cell.

Explanation:

In microbial growth experiments, when a bacterium is placed in a Petri dish with a solution that contains dissolved salt (NaCl) - a hypertonic solution -, the result will lead to the <u>dehydration and shrinking of the bacterial cell</u>.

This condition will eventually cause the rupture of the cell, resulting in the diffuse of H20 molecules from the plasma membrane, that is, the water moving out of the cell.
