Answer:
D). genetic drift
Explanation:
Genetic drift is the change in an allele frequency over a period of time. This event has to be random and a chance event.
For example: In a population of a flowering plant there are two types of flowers, blue and yellow. Due to a fire many yellow flowers are destroyed by chance. Now the resultant population will have more blue flowers and when they reproduce the population will eventually evolve to have more blue flowers. Effect of genetic variation is more pronounced in a small population since its easy to disturb the allele frequency.
<span>Controlled variable is a variable that was made constant in the research. That was because the controlled variables can influence the dependent or independent variable. If the variables is not made constant, it can alter the research result and made it invalid.
In this case, </span>the caffeine and alcohol intake might alter the physical activity or the blood glucose so it should be controlled.
Answer:
The increase in the reproductive success of a species will have the greatest impact on the prey of the animal.
Explanation:
The prey's population will decrease because there are more animals needing it to survive.
Like a wet sponge, soil already saturated from previous rainfall can't absorb much more ... thus more rainfall will become surface runoff.
Answer and Explanation:
The number of mitochondria in an insect's wing will be more than in the insect body. Wings are used for flight and therefore the energy demand is higher. Greater number of mitochondria in the wings increases the energy supply to the cells.
