Homeostasis is necessary for a cell to survive. What is the definition of homeostasis
Answer:
Homeostasis is the process of maintaining a constant internal environment suitable sustaining life.
Homeostasis continues to maintain ideal environment for enzyme action and all cell functions throughout the body.
Why homeostasis is necessary?It is the preservation of a constant internal environment in the face of changing internal and external conditions. These include blood glucose concentration control in the human body.
A series of control mechanisms at the organ, tissue, or cellular level maintain homeostasis.
Substrate supply, activation or inhibition of individual enzymes and receptors, enzyme synthesis and degradation, and compartmentalization are examples of control mechanisms.
The liver, pancreas, kidneys, and brain (hypothalamus, autonomic nervous system, and endocrine system) all contribute to homeostasis.
The liver is in charge of metabolizing toxic substances and maintaining carbohydrate metabolism with pancreatic signaling.
Thus, homeostasis is necessary for a cell to survive.

a student is investigating cellular transport. what will most likely occur when the student places a cell that is 95% water inside of a solution that is 100% water?
Cellular transport refers to the flow of substances into or out of the cell across the cell membrane.
When the student places a cell that is 95% water inside of a solution that is 100% water, the cell will achieve net movement and if water continues to enter, it swells up and burst.
When a cell is placed in a hypotonic solution, water flows into the cells and the cell gains volume until it achieves equilibrium. But if water continues to flow in afterwards, it swells up and burst.Learn more about cellular transport: https://brainly.com/question/6949569
The relatively large number of new mutations that occur in the human genome in each generation is tolerable because: ______________
a. humans have excellent protein repair mechanisms.
b. compared to other organisms, changes in human proteins have relatively small effects on their cells' structures and functions.
c. humans have excellent DNA repair mechanisms.
d. most of the human genome is noncoding DNA, so few mutations affect human proteins.
e. most of the mutations occur in somatic cells, not germ cells.
Answer:
The believe the correct answer is option E.
The relatively large number of new mutations that occur in the human genome in each generation is tolerable because: most of the human genome is noncoding DNA, so few mutations affect human proteins. Therefore, the correct option is D.
What is a human genome?A human genome refers to the complete set of sequences of the nucleic acids that are present in the humans. The human genome contains a relatively large amount of noncoding DNA, which does not code for proteins and is therefore less subject to selective pressures.
Option A, humans have excellent protein repair mechanisms, and Option C, humans have excellent DNA repair mechanisms, are partially true, but do not fully account for the tolerability of new mutations in the human genome.
Option B and E are also not true, as changes in human proteins have relatively small effects on their cells' structures and functions, is not entirely true. Therefore, the correct option is D.

How do gravity work?
Answer:
Gravity makes the Earth constantly pull us down. ... The force of gravity depends on the mass (weight) of each object. The force with which two objects attract each other is proportional to their mass and decreases rapidly the moment we separate them.
Explanation:

if you have been to a beach for a whole day, then you have seen tides roll in and out. What causes
Earth's high tides?
Answer:
The Moon
Explanation:
High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
Answer:
it's caused by the gravitational forces from the moon.
