Answer:
B
Explanation:
The windward position on a mountain is the side that is bombarded with prevailing winds. These winds are forced upwards into the upper cooler atmosphere by the physical barrier of the mountain. The moisture in the winds condenses forming clouds that precipitate as rain. As the winds descend on the other side of the mountain (leeward side), they have little moisture left. Therefore, the windward side will be rich in vegetation and biodiversity due to higher annual rainfall than the leeward side.
The nucleotide variation is obtained by comparing nucleotide sequence between individuals between individuals of a particular population. If genetic variability is 0 % then the number of alleles would be 1.
<h3>
What is genetic variability?</h3>
Genetic variability is the evolutionary process and development of new species. Genetic variability describes the dissimilarities such as brown eyes, blue eyes that happen naturally when DNA is altered.
Genetic variability varies in population. Genetic variability describes the tendency at which traits in a population may vary.
Gene variation refers to a differences in the genetic makeup of the individual. Genetic variation is a important process of natural selection and biological evolution.
Therefore, The nucleotide variation is obtained by comparing nucleotide sequence between individuals between individuals of a particular population. If genetic variability is 0 % then the number of alleles would be 1.

Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds.
Answer:
That is administered and controlled
Step-by-step explanation:
A variable is the condition or a product that may vary without the influence of any investigator. Such variables can be found abundantly in our daily lives, ranging from air to sunlight. Controlling such variables ensures the limitation of their influence on the outcome of an experiment. In connection to this experiment, the variables that are controlled are the mineral content in the water, the amount of bacteria food, the amount of light and the the constant temperature of 20 degrees C.
If not administered or these variables controlled, the experiment would not clearly explain the impact of caffeine on the heart beat of the water fleas as other variables may have influenced it. Thus variables are controlled to study the singular impact of any agent or effect.
Organisms that use the same resources because there may not be enough for all, so it then becomes a competition of who gets it and who doesn't.
