Answer:
The correct answer is Zones of tolerance
Explanation:
All living organisms such as fish,plants and animals need water to survive and also the require certain pH level of water in order to be healthy.Its a acid and base balance reaction.Strong acids dissolve into water and its changes water's pH.if water's pH level drops it becomes acidic suppose a fish waste ammonia releases and dissolves in water to form harmless ammonia ions,carbon dioxide ions and hydrogen ions even some limestone also rises pH level and water becomes more basic.To make the tank water alkaline, add some corals and aerate the tank water by fixing an air pump so that excess of carbon dioxide eliminate out and water pH level comes to neutral this is the reason water becomes slightly alkaline and the fishes are able to reproduce.
Answer:
B. Sea stars are the prey of seagulls
Explanation:
Seagulls eat sea stars, meaning that sea stars are their prey (the organism that is eaten).
Predator: an organism that eats (preys on) another organism
Prey: an organism that is eaten by another organism (creatures can be both predator and prey. For example, a rabbit is a predator to grass, while they are prey to foxes)
Host: An organism that is fed on by a parasite. Think of a dog with a tick. The dog is the host, the tick is the parasite.
Incorrect answers (and why):
A. Sea stars do not eat seagulls
C. If a sea star was a predator to a seagull, that would mean that they eat seagulls. They do not.
D. A host is an organism that a parasite preys on. Not only are sea stars not parasites, but they definitely do not prey on seagulls.

The question is incomplete as it lacks the question and has only information regarding the question. however, the correct question is as follows :
How many different genes are contributing to the wingless phenotypes in these mutant fly strains?
Answer:
The correct answer is - Two genes.
Explanation:
In the given question there are two mutation groups based on the given seven results:
1st group :
Mutations 1, complement with 2,4, and 7 and also complement each other, thus, are on the same gene.
2nd group:
Mutations 3, 5, and 6 did not complement each other but complemented with mutations 1, 2, 4, and 7. Thus, these three mutations are present together on a different gene.
