Answer:
the study of all living things
Explanation:
Answer: The answer is smaller
Explanation:The illuminated part of the moon is getting bigger. To decrease gradually in size. The illuminated part of the moon is getting smaller.
Answer: Directional selection
Explanation:
In the population genetics, directional selection is the mode of selection during which the extreme phenotype are favored more than the other phenotype.
This causes the allele frequency to shift towards the time in the direction of that particular phenotype.
Here, in the question the acid tolerant plant species is favored over the other phenotype.
Hence, the correct answer is option D
Genetic Drift is a term used to describe part of the evolutionary process. Genetic Drift is a term describing the random environmental factors such as volcanic eruptions, trees falling down, forest fires etc, that affect the gene frequency in the population of a species after the event has taken place. So, we can say that genetic drift in a population can affect the gene pool by either allowing the gene pool to increase of decrease. A typical example is that of the worldwide rhino population. The more the rhinos are poached, the smaller the genetic pool becomes. Eventually this can lead to the extinction of the species.
