In the lab, you isolate a chlorella mutant that is unable to switch xanthophyll pigments into the inactive, non-heat-dissipating
REY [17]

Answer:

No, because xanthophyll dissipates absorbed light as heat, and in low light environments, such dissipation would decrease photosynthesis and therefore growth.

Explanation:

Xanthophyll is one of the accessory pigments present in organisms. Being an accessory pigment, the function of xanthophyll is to dissipate the absorbed visible light. Since it dissipates the visible light, the light cannot be used by Chlorella to drive the light-dependent reactions of photosynthesis.

When a mutant Chlorella is grown in the shady region, the dissipation of light by xanthophyll would further reduce the rate of photosynthesis. This mutation is not an adaptive feature in shady regions where the rate of photosynthesis is already lower due to limited availability of light and therefore, would not be favored by natural selection and would not spread to the future generations.

They are both hormones that regulate blood-sugar levels

Explanation:

Insulin is a hormone that controls the blood glucose level. It released in the blood stream when the glucose level increases after eating food. It is produces by pancreas, insulin helps the glucose to enter the body's cells where it can either be stored for future use or can be used for energy.

Glcogen  is produced by alpha cells of pancreas, it is a peptide hormone. Its main function is to raise the concentration of fatty acids and glucose in the bloodstream. It is one of the main catabolic hormone of the body
