Answer:
Crossing Over Occurs in Prophase I of Meiosis
It is where a piece of a non-sister chromatid exchange DNA with another Non-Sister to increase genetic diversity
Explanation:
Aldosterone hormone would be released in high quantities
when the electrolyte balance in the body is low. This would enable the sodium
ions to be reabsorbed from the glomerular filtrate by the nephrons’ tubules.
ADH (Anti-duretic hormone), on the other hand, would be released in high amounts
if the electrolyte concentration in the body is high. This would enable the
high re-absorption of water from the glomerular filtrate.
If u meant algae,
Algae form organic food molecules from carbon dioxide and water through the process of photosynthesis, in which they capture energy from sunlight. Similar to land plants, algae are at the base of the food chain, and, given that plants are virtually absent from the oceans, the existence of nearly all marine life—including whales, seals, fishes, turtles, shrimps, lobsters, clams, octopuses, sea stars, and worms—ultimately depends upon algae. In addition to making organic molecules, algae produce oxygen as a by-product of photosynthesis. Algae produce an estimated 30 to 50 percent of the net global oxygen available to humans and other terrestrial animals for respiration.

Answer: The question is not complete, the options are not given.
But the correct answer is.
They are likely symbiotic with the dorminant species.
Explanation:
A keystone species is a species which has disproportionately large effect on the communities it hold together by maintaining the biodiversity of the ecosystem and causing the abundance of other organisms present in the ecosystem. They play a role in the existence of species present in their environment.
The tree types of keystone species are predators, mutualist and ecosystem engineers.
