A wildlife biologist suggests re-introducing the eastern cougar into southern Alabama, reasoning that besides bears, which can survive off of berries and grubs, there are no large natural predators, and that it would be good for the food chain. It is assumed that the eastern cougar would eat deer, which in turn, graze on tree bark, shrubs, and leaves. The average cougar weighs about 100 pounds, as does the average deer. The average cougar has a range of one square mile. A recent biological study showed that there were about 16 deer per square mile in Alabama, an average about 40,000 pounds of vegetation per square mile, and an average of 9.5 people per square mile in southern Alabama. Despite the biologist's proposal, other biologists vote against re-introducing the cougar. Which of these is a possible VALID reason for this?

The answer is

B

Convection currents raise the less dense hot material from the center to the cool crust and material from the cool (dense) crust settles down to the core to be heated again.

Famine

In the early 14th century, Europe encountered a series of famines, often referred to as the Great Famine. Abundant rains in the spring of 1315 were partly responsible, along with cool warmth. This did not enable the cereals to ripen, which led to crop failures. It also recommended that straw and hay could not be preserved for animals and that salt was not available because the ocean could not evaporate. Moreover, the population had expanded very suddenly prior to 1300, so there was an additional requirement on limited sources.

Answer:

A disease or infection of the inner ear.

Explanation:

The inner ear infection or inner ear disease can be described as inflammation of inner parts or ear, which are responsible for the hearing and balance, such as swimmer's ear (also known as otitis externa).

Swimmer's ear represents an ear infection, characterized by inflammation or irritation of ear canal, swelling and pain in ear canal, moist earwax, and decreased hearing.

Thus, the correct answer is option). 'a disease or infection of the inner ear.'

The two given terms congenital and strangulated are related to the surgical procedure which is known as hernioplasty. Hernioplasty involves the surgery of hernia, in which the organ is repaired by putting a mesh over the weakened portion of it. Hernia can be defined as the medical condition when a part of the internal tissue, or an organ breaks through a hole in the overlying muscles.

Hence, the answer is 'hernioplasty'.

Answer:

These two terms are related to Hernia repair, hernioplasty,  

herniorrhaphy

Explanation:

Hernia repair or hernioplasty or  herniorrhaphy represents the same terminology and it is a form of surgery which is done usually when a hole occurs in a muscle due to the break down of an organ or tissue. In this surgery, the displaced tissue is brought to its appropriate position.

Strangulation of  hernia is done when any part of an organ or tissue stuck inside hernia thereby blocking the blood supply.  

While Congenital hernia surgery is done when a part of  abdominal organ moves below the hernia sac, .  

The correct answer is: population, community, ecosystem.
