The Expiratory Reserve Volume will decrease when an individual is treading water in a lake.
What is Expiratory Reserve Volume?Expiratory Reserve Volume, ERV, is the additional volume of air which can be forcefully expired with maximum extra effort beyond the volume that can be expired in normal expiration.
ERV normally decreases with exercise.
Therefore, the Expiratory Reserve Volume will decrease when an individual is treading water in a lake.

3. What drives the ATP synthase reactions that produce ATP?
A the redox reaction that changes NADH to NAD*
B the formation of water at the end of the electron transport chain
C the energized electrons from the electron transport chain
D the hydrogen ion concentration gradient across the membrane
Answer:
D the hydrogen ion concentration gradient across the membrane
Explanation:
gradient created by this drives hydrogen back through the membrane, through ATP synthase
Hydrogen ions flow down a concentration gradient from the thylakoid space to the stroma through ATP synthase, releasing energy that can be used to produce ATP from ADP + Pi
ATP synthase is a mitochondrial enzyme localized in the inner membrane, where it catalyzes the synthesis of ATP from ADP and phosphate, driven by a flux of protons across a gradient generated by electron transfer from the proton chemically positive to the negative side.
At the electron transport chain, hydrogen is built up on one side of the electron transport chain and the electrons which are their way down the chain are building up on the other side. The electrons and hydrogen are attracted to each other due to their charges. These for the hydrogen flows though the gradient in the membrane to reach the elections. Once the hydrogens pass though this gradient it produces the ATP from the hydrogen
Once the hydrogens pass though this gradient it produces the ATP from the hydrogen “turning” the protein. At the end the oxygen is placed at the bottom of the electron transport chain to accept the hydrogen which makes water

HELPPP ASAP!! A population of skunks lives in a woodland habitat. The skunks are unable to leave the habitat because of a large mountain. Describe two reasons this population is not at Hardy-Weinberg Equilibrium.
Some of the conditions are there that must be met for a population or an allele to be in Hardy-Weinberg equilibrium equation are:
1. The population of species must be very large.
2. There must be no migration and population must be isolated in a species.
3. There must be no mutations in a population of species.
4. There must be random mating, which means there are no mating preferences.
So, a population will not be according to Hardy-Weinberg Equilibrium if it is small, or there are , which is not raised, but mutations are expected to occur in future. Skunks can also migrate to another region of a woods despite the presence of a large mountain. As a result of possible mutations and migrations, the population is not in Hardy-Weinberg equilibrium.
