Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin. Acetylcholine, gastrin, and histamine stimulate the proton pump in parietal cells to release hydrogen ions and decrease pH.

Explanation:
Crossing over doesn't occur only between heterozygous genes, it also doesn't happen only in some chromosomes and it never reduces de variation, otherwise, the crossing over is one of the main causes of variation among species.
Answer:
Carrying capacity for the jellyfish would reduce
Explanation:
Carrying capacity of a biological population in an ecosystem is the maximum number of population size the environment or habitat can conveniently cater for given the available resources such as, food, water supply, space etc.
The survival of the jelly fish largely in the small body of water would be largely dependent on how much food that is available.
The large number of mollusks harvested would reduce the available food in the small body of water, hence, reducing the carrying capacity for jellyfish.
