Which of the following is most likely to be the direct result of lack of genetic diversity in a food crop such as corn?(A) Decre

ased kernel size- kernel size does not affect the corn’s ability to reproduce and grow.(B) Decreased potential yield- the potential yield of corn does not helpcause the corn to become extinct.(C) Decreased dependence on chemical fertilizers- because a decreased dependency on chemical fertilizers would make the corn stronger, and a lack of genetic diversity makes it weaker.(D) Increased susceptibility to plant disease- if corn is more susceptible to plant diseases, then it will be at a risk of extinction.(E) Increased resistance to pests- would make the corn stronger, and a lack of genetic diversity makes it weaker.

Answer:

(D) Increased susceptibility to plant disease- if corn is more susceptible to plant diseases, then it will be at a risk of extinction.

Explanation:

Genetic variation helps a population to develop despite varying environmental conditions as to decrease the risk of extinction. Genetic diversity is used to create improved crop varieties with traits such as yield, pest resistance and environment stress. Lack of genetic diversity in corn will make it susceptible to plant diseases and be at risk of extinction.

In order to carve out valleys, glaciers have to be strong enough to drag rocks and boulders down the mountainside, but what else
Snowcat [4.5K]

Answer:

e. To create valleys, glaciers have to be constantly advancing.

Explanation:

Although glaciers look like massive, solid blocks of ice, they actually move in a very slow manner, which is difficult to detect by the naked eye. The pressure that the glacier receives from the weight of the ice causes it to deform. As these changes occur, the melt water at the bottom of the glacier allows it to slide. It is this movement that allows for the formation of glaciers, as glaciers have to be constantly advancing in order to form valleys.

A high gradient in air temperature and pressure can cause a jet stream, characterized by high-speed winds. Through which marked
solong [7]

Answer:D -it causes high-pressure air mASses to rotate clockwise

Explanation:

Jet stream is a very fast air stream that occurs in the upper troposphere. Jet streams occur around the earth surrounding it and following an undulating course. These air jets were discovered during the air raids in World War II.

Occurring in the upper levels of the troposphere, this current is of great importance to aviation and can be harnessed to provide fuel economy to the aircraft that penetrate them by taking advantage of the momentum provided by their intense winds. There are two types of jet stream: the subtropical jet, with higher altitude being found between latitudes of 20 ° and 30 °; and the lower altitude polar jet, being generally located between the circumpolar region and the average latitudes (40 ° -70 °). Regardless of the type, jet streams form a boundary between a cold air mass and a hot air mass.
