Answer:

The event that could not be caused by a population bottleneck is increased population size.

Explanation:

Population bottleneck (genetic bottleneck) is a phenomenon that causes a sharp reduction in population size. It is caused by various factors like environmental disasters such as disease, famines, earthquakes, floods, etc or human activities like hunting, genocide, destruction of habitat, etc. These factors reduce the genetic variation in a population and cause smaller genetic diversity in a smaller population. This causes a change in allele frequency (genetic drift) and it leads to loss of alleles. The effects of genetic drift are stronger in smaller populations than large ones. The small population size increases the chances of inbreeding, accumulation of harmful mutations and genetic homogeneity which leads to inbreeding depression.

An example of a population bottleneck is Cheetahs, which suffers a reduction in genetic diversity during their bottleneck. As a result, they have problems in their reproduction and are highly susceptible to diseases.

The answer is spongy mesophyll.

Explanation:

Between the upper and lower epidermis of a leave, you can find the so called mesophyll tissue which is rich in chloroplasts. There are two types of mesophyll tissue: the palisade and the spongy mesophyll. Whereas the cells of the palisade mesophyll are tightly packed, the cells of the spongy mesophyll are loosely packed.

Which of the following stimuli would cause the liver to produce more glycogen?

Musya8 [376]

Answer: Option B

Explanation:

Glycogen is a hormone which is used to regulate the amount of glucose in the blood. Insulin and glycogen are two hormones that helps in regulation of the blood glucose.

When there several hours of fasting then there is decrease in the level of glucose in the blood then the glycogen is produced to meet the required amount of glucose in the blood.

1. A mutation is capable of reducing the amount of chlorophyll in the leaf. Would this also reduce the rate of photosynthesis?

Alex17521 [72]

Answer:

No.This is because the amount of the chlorophyll; ls not a limiting factor of photosynthesis.

Explanation:

Generally the three factors are regarded as the limiting factors of photosynthesis.These are the CO2 concentration,light intensity,and temperature.Fluctuations in the availability of these factors affects the rate of photosynthesis.

When the rate of a chemical reaction depends on a lot of reactions for its progress.The rate of this reaction is determined or limited by the slowest in the reactions. This series of reactions govern this chemical reactions are the limiting factors. The one that is slowing down the rate of the reaction is said to limit it.

in the case of photosynthesis, a decrease in the amount of CO2,but no change in the amount of other factors would affect the rate of photosynthesis. This is applicable to other factors fluctuation too ,which limits the rate of photosynthesis
