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?

Answers

The biologists are worried that the cougar will be harmed or harm people's in the cougar's range.
because since it only has one natural predators and not more when it start reproducing there will be no predator to keep the population in check which then later can mess up the whole ecosystem or something. I am not sure though.

Why would the population of rabbits decrease if the population of mice decreased?

Answers

The predators of mice would not have enough to feed on due to competition within its species, and so it might eat rabbits instead, as it can change the species on the food web.
Because the predators would start to prey on other small animals such as rabbits since there are less mice.

Predatory fish that swim in the water column, usually have what kind of coloration?disruptive
counter shading
cryptic
fusiform

Answers

The answer is counter shading.

Countershading is used by the predatory fishes. It is a form of camouflage in which the animal's pigmentation is darker on the upper side and lighter on the lower side of the body. It made the predators detection from the prey but counterbalancing the effects of self-shadowing. 

Difference between autosomes and gametes

Answers

Answer:

An autosome corresponds to a somatic chromosome, which defines structural and functional characteristics in an individual, while the gamete is a cell containing autosomes, useful in sexual reproduction.

Explanation:

The somatic chromosomes are called autosomes, since they contain the genetic information necessary to define the structure and functions of a living being. In humans, there are 23 pairs of chromosomes, of which 22 pairs correspond to autosomes.

The gametes, or sex cells, are in charge of transmitting the genetic information from parents to offspring, and are formed by chromosomes. As gametes are haploid cells, they possess half of the chromosome load, that is, in the human being there are 22 autosomes.

Generally speaking, an autosome is a somatic chromosome, while a gamete is a cell containing autosomes.

Answers

Final answer:

Genetic testing is the scientific factor that has most advanced livestock breeding, as it allows breeders to identify specific genes and traits in animals, helping them make informed breeding decisions.

Explanation:

The scientific factor that has most advanced livestock breeding is genetic testing.

Genetic testing allows breeders to identify specific genes and traits in animals, helping them make informed decisions about which animals to breed.

By selecting animals with desired genetic traits, breeders can improve the quality and productivity of livestock over time.
