how ribosomes help cell maintain homeostasis
Answer:
Ribosomes create the thermoreceptors of the body. Another example of a homeostatic condition maintained by proteins is blood-glucose levels. When our blood-sugar levels get too high, specialized cells in the body release a protein hormone called insulin.
Explanation:

Have A Great Day
~Zero~
Answer: Ribosomes play a key role in homeostasis. Without ribosomes, a cell would not make proteins. A cell with no ribosome would simply not function. With no protein reproduction to maintain the cell wall there would be no barrier to keep invasive bodies from damaging the inner workings of the cell, there would be no way to produce the needed proteins for rebuilding and maintaining the cell.

how are utah and mexican praire dogs genes alike
Answer:
In terms of genetic variation, allelic richness (A) estimated through rarefaction resulted in 1.6–3.0 mean alleles per colony, and no private alleles were found. Mean genetic diversity (HE) was 0.525 (SD = 0.11), with values ranging from 0.276 (SD = 0.25) to 0.618 (SD = 0.09).
Explanation:
Utah prairie dog (Cynomys parvidens), and Mexican prairie dog (Cynomys mexicanus)—all of which may be considered rare (Hoogland 2006a). After 200 years of shootings, poisonings, conversion of habitat, and more recently plague, prairie dog numbers are a fraction of what they once were.

Answer:
The Cerebellum's Balancing Act
Explanation:
The cerebellum is at the back of the brain, below the cerebrum. It's a lot smaller than the cerebrum. But it's a very important part of the brain. It controls balance, movement, and coordination (how your muscles work together).
Muscle control and body coordination are controlled by the cerebellum.
The cerebellum is a highly specialized region of the brain located at the back of the skull, beneath the cerebrum. It is usually referred to as the "little brain" due to its appearance and position. Although it constitutes only about 10% of the brain's total volume, the cerebellum contains an enormous number of neurons.
It plays a crucial role in motor control, coordination, and balance. It receives information from various sensory systems. It also receives input from the cerebral cortex, which is involved in planning and initiating movements.

Blue crab is an important resource in my region. It is harvested in Chesapeake Bay. People in my region have been eating blue crabs for hundreds of years. Blue crabs are usually harvested in traps called crab pots. Most crabs are harvested commercially, but recreational crabbing is also important. Crab harvesting in Chesapeake Bay is regulated by the states of Maryland and Virginia, and special licenses are required. Limits are placed on the number of crab pots and the sizes of crabs that can be kept. Even though regulations are in place to protect the crabs, their numbers are declining due to deteriorating water quality in Chesapeake Bay. The crabs require additional protection, but too many restrictions could put people out of work because blue crabs are a popular, traditional food in the region, and thousands of people make a living from crab fishing. The natural resources management of the crabs is inadequate because the crabs continue to be harvested in an unsustainable way.

In an area of East Texas, the most intense competition would most likely occur between white-tailed deer and
A. brown bears
B. squirrels
C. other white-tailed deer
D. coyotes
Given what we know, we can confirm that the most intense competition would most likely occur between white-tailed deer and other white-tailed deer.
Why would white-tailed deer most likely compete with themselves?This has to do with food sources. Of the many animals listed, none of them share a food source with the white-tailed deer. The deer are herbivores that feed primarily on grass and shrubs. The bears and coyotes are carnivores that feed on other animals such as the deer themselves. While squirrels are herbivores but do not compete with the deer for food.
Therefore, given that other deer are the only animals listed that are after the same food source, we can confirm that the most intense competition would most likely occur between white-tailed deer and other white-tailed deer.
