I believe this problem has the following choices:

 

a. It was hard to get the fish to breed and produce offspring for the aquaculturist to raise.

b. Because the fish were stressed in tanks, they required much more food, reducing the profitability of rearing the fish this way.

c. The fish had to be raised in a community with several species of fish in the same tank, and they would attack and eat each other.

d. Marine fish are more aggressive than their freshwater relatives and they tended to fight a lot, often killing some of the other fish in the tank.

 

The correct answer is:

c. The fish had to be raised in a community with several species of fish in the same tank, and they would attack and eat each other.

Chromosomes are like a ball of yarn in the sense that there are multiple components that make up the structure. Genes can be in similitude of the smallest threads in the yarn and when a multitude of genes are put together they make a DNA strand or a long, thick thread of yarn.

The equation shows cellular respiration. During cellular respiration, glucose combines with oxygen to form carbon dioxide, water
Pani-rosa [81]

Answer;

-During the process of cellular respiration, the energy stored in glucose is transferred to ATP.

Explanation;

-During Cellular Respiration, sugar is broken down to CO2 and H2O, and in the process, ATP is made that can then be used for cellular work.

-During this process, the energy stored in glucose is transferred to ATP. Energy is stored in the bonds between the phosphate groups (PO4-) of the ATP molecule.

-Energy is then  liberated from the ATP molecule to do work in the cell by a reaction that removes one of the phosphate-oxygen groups, leaving adenosine diphosphate (ADP). When the ATP converts to ADP, the ATP is said to be spent.
