3. any trait that confers even a small increase in the probability that its possessor will survive and reproduce will be strongly favored and will spread through the population.
Explanation:
- Natural selection is a nonrandom process by which biological traits become more or less common in a population as a function of the differential reproduction of their bearers of differences in the rate of survival.
- Natural selection can act on any heritable phenotypic trait and operate among any entities that reproduce, show inheritance of their characteristics from one generation to the next, and vary in fitness.
- Natural selection is the machine that drives evolution. It also explains adaptation.
Answer: Blood sugar/blood glucose levels are controlled by negative feedback involving the hormones human insulin and glucagon.
Explanation:
Insulin is produced in the increased , if there is too little glucose in the blood the pancreas is triggered and released more insulin to change glucagon into glucose, this regulates the amount of glucose in the blood. However if there is too much glucose in the blood (after a sugary meal) the pancreas is triggered to use insulin to lower the blood glucose levels, this is called negative feedback. This works by storing glucose as glucagon in the blood, insulin can be objected into the blood stream if a person needs it straight away(eg type 1 diabetes.)

The right answer is mitosis.
Mitosis refers to the chromosomal events of eukaryotic cell division. This is a nonsexual / asexual duplication (unlike meiosis).
It also refers to a very particular stage of the eukaryotic cell cycle, called the "cell cycle", which is the stage of duplication of each chromosome of the mother cell and of their equal distribution in each of the two daughter cells.
Mitosis allows the formation of two daughter cells strictly identical genetically to the mother cell.
