Answer:
Mutations and crossing over during sexual reproduction
Explanation:
Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Genetic variation can be a result of sexual reproduction during when chromosomes crossover during Meiosis I, which leads to the creation of new combinations of genes.

The Krebs cycle is a series of biochemical steps that lead to the complete oxidation of glucose, resulting in the production of carbon dioxide, water and relatively large amounts of ATP. A link reaction is the reaction needed to move the products of glycolysis into the Krebs cycle.
Hope this helped!
The diffusion of chemicals and gases in and out of cells is an essential activity in human organs. Diffusion of oxygen and carbon dioxide gas occurs in the lungs. Diffusion of water, salts, and waste products occurs in the kidneys. Diffusion of calcium from food into cells occurs in the intestines.
What type of diffusion?
Answer:
A) The outcome of the experiment is that accumulated best in section C. This is because 64 fish were in this section which is the largest amount.
B) one variable that was uncontrolled was that fish were not forced to go into a certain section. They had a chance to accumulate by themselves. If this was controlled, fish wouldn’t be able to adjust by themselves, they would be forced in a section they might not accumulate well in. Another uncontrolled variable would be amount of food you give them. This affects the result because if you don’t feed them, they will die. If you feed them too much, they over eat and die. C) The temperature can affect the physiology because if it is too cold for the fish, they will go to another section until they are warm. If it is too hot for the fish, they will go somewhere cooler.
