Answer:
E. A, B, and C are all correct.
Explanation:
Microevolution is an evolutionary change that is said to occur on a small scale within a population of species over a short period of time. This can be seen in the case of the population of alpine plants. The change is within the population.
Genetic drift, by definition is the change in the allele frequencies, as can be seen in the alpine plants, which is brought about by a bottleneck effect. In order words, bottleneck effect occurs when a population size is reduced drastically as a result of environmental events such as landslide, that can be seen in the case of alpine plants. This genetic drift example randomly selects the surviving individuals in this microevolution.

Answer:
The 2 carbon compound is called Acetyl CoA. Acetyl CoA now enters the citric acid cycle or the Krebs cycle.
Explanation: 2 molecules of pyruvic acid are the products of the enzymatic degradation of one molecule of glucose in a process known as glycolysis. Each molecule of Pyruvic acid (a 3 carbon molecule) is further degraded to a 2 carbon molecule called Acetyl CoA. Each molecule of Acetyl CoA then enters the citric acid cycle where it is used to produce 1 molecule of GTP, 3 molecules of NADH and 1 molecule of FADH2. NADH and FADH2 then enters the electron transport chain where they are used to generate ATP in a series of enzyme catalyzed reactions.
Answer:
Trees reduce the rate of erosion
Explanation:
Trees reduce the rate of erosion by: protecting the soil from the impact of rain. transpiring large amounts of water, which counteracts very wet soil. binding soil to sloping land with their roots
Aristotle based his classification system off of observations of animals, and used physical characteristics to divide animals into two groups
