Why is it important for the cell membrane to allow materials to enter and leave the cell

Biology
1 answer:
umka21 [38]3 years ago
5 0
<span>Cell membrane needs to allow and exit the materials that enter the cell because the cell needs nutrients and these nutrients are converted into molecules that aid in many cellular activities like repair, divide and form structures and biomolecules.
Also to excrete wastes and other harmful materials for the cell.
This continues because the cell wants to attain homeostasis.

Homeostasis is the state where the internal and external part of the body maintains and establishes balance and equilibrium. This is achieved through cellular processes in the body, the integumentary system regulates the body temperature, the hypothalamus –hunger and thirst of the individual and other interrelated organ systems that make the body healthy and in the state of equilibrium. Now, when diseases or disorders appear they disrupt the organ systems in the body thus, causing imbalance state –high fever, inability to focus and etc.<span>

konstantin123 [22]

According to the evolutionary theory, over the history of the human species, aggressive males have had the greatest impact on the gene pool. It is natural selection.

<h3>What is evolution?</h3>

The term evolution refers to descendence with modification, which mainly occurs due to natural selection.

Natural selection refers to the differential process of survival and reproduction of the fittest individuals in a population.

Aggressivity may thus represent an adaptive feature (i.e., an adaptive trait) in human evolution.

A neutron star collapses into a black hole because of the force of (fusion,gravity)
stealth61 [152]
Gravity

Neutron stars are the most extreme and fascinating objects known to exist in our universe: Such a star has a mass that is up to twice that of the sun but a radius of only a dozen kilometers: hence it has an enormous density, thousands of billions of times that of the densest element on Earth. An important property of neutron stars, distinguishing them from normal stars, is that their mass cannot grow without bound. Indeed, if a nonrotating star increases its mass, also its density will increase. Normally this will lead to a new equilibrium and the star can live stably in this state for thousands of years. This process, however, cannot repeat indefinitely and the accreting star will reach a mass above which no physical pressure will prevent it from collapsing to a black hole. The critical mass when this happens is called the "maximum mass" and represents an upper limit to the mass that a nonrotating neutron star can be.

However, once the maximum mass is reached, the star also has an alternative to the collapse: it can rotate. A rotating star, in fact, can support a mass larger than if it was nonrotating, simply because the additional centrifugal force can help balance the gravitational force. Also in this case, however, the star cannot be arbitrarily massive because an increase in mass must be accompanied by an increase in the rotation and there is a limit to how fast a star can rotate before breaking apart. Hence, for any neutron star, there is an absolute maximum mass and is given by the largest mass of the fastest-spinning model.

If an animal cell has excess energy, what is most likely to happen to this energy?
Len [333]
I think the correct answer from the choices listed above is the last option. If an animal cell has excess energy, most likely it  will be stored as fat molecules. <span>Anabolic process  is done to synthesize Triglycerides (Fat) to store for a rainy day. Hope this answers the question. Have a nice day.</span>
