<u>Answer:</u>
<em>A plasma membrane is the cellular structure that makes it possible for a cell to differ structurally and biochemically from its surroundings. </em>
<u>Explanation:</u>
<em>Plasma membrane</em> is the surrounding of all the cells. The function of plasma membrane in a cell is to regulate the incoming and outgoing elements from the cell.
<em>Phospholipid bilayer</em> is the main composition of plasma membrane. It makes the cell different from each other structurally as well as makes the cell different in <em>chemical composition </em>too.
Answer:
b.Movement of phospholipids in the plasma membrane from one monolayer to the other requires the polar or charged head groupd to enter the hydrophobic interior of the lipid bilayer. This process requires a large positive change in free-energy, thus making this type of movement unlikely without an input of energy
The plasma membrane serves a protective function for the cell and is a selective membrane for particles entry
Answer:
To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells.

Biotic:
Animals: animals are consider biotic because they are living things, they breath, walk, eat, sleep, reproduce, and drink water. and since biotic means living things, the animals are under the biotic category.
Plants: same as animals, but with plants they reproduce asexually meaning it requires only one organism to produce another life. Anything with cells in them are consider a living thing.
bacteria: same as plants and animals, they have cells so they are consider a living thing.
There are other types of biotic factors out there like producers, consumers and decomposes. Here are the ten things of biotic:
1. Bamboo plants (producers)
2. Banana Trees (producers)
3. orchids (producers)
4. Seaweeds (producers)
5. anteater (consumers)
6. Bears (consumers)
7.zooplankton (consumers)
8.bacteria (decomposers)
9. earthworms (decomposers)
10. termites (decomposers)
Those are the ten examples of biotic.
Abiotic:
Some of the examples include temperature, sunlight, soil, gases and atmospheric, these are consider the non-living things but here are 5 examples of abiotic factors in the ecosystem.
1. Altitude
2.pollution
3.soil
4.wind
5. Ph
Hope this helped :)
Have a great day
