Answer: physiological

When we are under constant stress, our body will start expressing it with physiological responses. When the body realizes the presence of the stressor agent, sends signals to the hypothalamus, and it activates the sympathetic and hormonal responses to eliminate the stress.
The digestive tract is a part of the body very commonly affected by stress.

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.

When the protein gramicidin is integrated into a membrane, an H+ channel forms and the membrane becomes very permeable to proton
Aleks [24]

Answer:

Explanation:

because a proton gradient is necessary over the inner mitochondrial membrane during oxidative phosphorylation for ATP production, ATP production will decease if gramicidin is added because the inner mitochondrial membrane will become permeable and the protons will be able to move in and out, there will be no electrochemical gradient left to drive ATP production. Electron transport will not be altered because it is dependent on the availability of NADH and FADH2. proton pumping also will remain the same but it will be useless because the protons can go back and forth
