Answer:
The correct answer is - 6.5 to 7.5 pH.
Explanation:
The proper acidity or alaklinity or pH of an environment affect the growth of the microbes. The most suitable pH value for the most of the microbes are between 6.5 to 7 pH.
Most bacteria influences bacterial growth positively around neutral pHvale which is 6.5 to 7.5. However, some present in acidic nature called acidophiles as they can tolerate pH value of 1.
Thus, the correct answer is - 6.5 to 7.5 pH.
Answer:
b. founder effect
Explanation:
When there is a situation when sufficient number of members of one species are reproductively isolated, and if there is an evolutionary pressure for them to start developing new advantageous traits, then a new species will gradually emerge. In this kind of scenario the genetic diversity will be minimized, as the number of individuals is much smaller, and that will result in only changes that will go in only one direction and they will also occur quicker than if there was a greater genetic diversity. This is called the founder effect, and it is easy to see why this term has been chosen, as the limited number of members of a species that have been reproductively isolated are giving the foundation for the development of a new, separate species.
B cause when there is a drought that means there are no water around, so that means that some of the eggs will dry out.
