Answer:
The answer to your question is: The second option is correct.
Explanation:
Pospholipid bilayer is a thin lipid layer that protects and isolate the cell from the enviroment, also it controls the the entrance of molecules to the cell and ejects wastes. So it is extremely important.
it is not important This could not be the right answer, bilater is very important.
to maintain a proper internal environment I think this is the right answer because among others, membranes mantain a proper internal environment.
to link cells together This option is incorrect, because membranes do not link cells.
ok well first it does two things it changes its shape (denature) and it slows down so its either b or d
They cool off the water or warm it up
The food chain that is shown in the food web could be any of the following:
- tree → deer → mountain lion
- grass → rabbit → mountain lion
- grass → rabbit → hawk
- grass → grasshopper → frog → snake → fox
- grass → grasshopper → snake → hawk
- grass → grasshopper → snake → fox → mountain lion
- tree → caterpillar → robin → fox → mountain lion

A food chain shows a unidirectional feeding relationship among organisms in an ecosystem. The organisms occupy a certain "place" in the food chain called trophic level. Food chains may have several trophic levels which always begin with the producers.
- Producers are organisms which make their own food. Plants are examples of producers.
- The organisms the directly feed on the plants are called the primary consumers. They are either herbivores or omnivores.
- The organisms that feed on the primary consumers directly are called secondary consumers. Those that feed on the secondary consumers are called tertiary consumers and quaternary consumers feed on tertiary consumers. These are either omnivores or carnivores.
- The apex predator is the animal at the top of the food chain. It is preys on the organisms in the lower trophic levels but nothing preys on it.
A food web, on the other hand, is a series of food chains showing the interdependence of organisms in an ecosystem.

<span>In order to determine the sugar molecule associated with the nucleic acid, we must first determine if the nucleic acid is a deoxyribose nucleic acid (DNA) molecule or a ribonucleic acid (RNA) molecule. We can determine this by looking at the bases in the molecule, as DNA has thymine and RNA has uracil. After the type of molecule is determined, the nature of the sugar is given by the name. DNA has deoxyribose and RNA has ribose</span>
