Materials are able to move across a cell membrane through one of two methods: active transport or passive transport. What is the difference between active transport and passive transport?A. Active transport requires the cell to form vesicles, while passive transport requires the use of membrane pumps.

B. Active transport is the only form of transport that requires the use of protein carriers.

C. Active transport requires the cell to expend energy, while passive transport does not.

Answers

Answer 1
Answer:

The difference between active transport and passive transport is that active transport requires the cell to expend energy, while passive transport does not, which is option C.

What are active transport and passive transport?

Cell membranes are selectively permeable barriers that allow certain materials to pass through while blocking others. In order to cross the membrane, materials move through transport processes. There are two main types of transport: active and passive. Passive transport is the movement of materials across the cell membrane without the input of energy. This includes diffusion, osmosis, and facilitated diffusion. These processes are driven by a concentration gradient, which is the difference in concentration of a substance between two areas. Active transport, on the other hand, is the movement of materials across the cell membrane that requires the cell to expend energy.

Hence, the difference between active transport and passive transport is that active transport requires the cell to expend energy, while passive transport does not, which is option C.

Answer 2
Answer: the answer is C, because in active transport molecules are moving against the concentration gradient which is from low pressure to high pressure (pushing against the pressure). whereas in passive transport it is moving with the flow of the concentration gradient which is from High to low (moving with the pressure).

Author's last name, page number where quote appears information MUST follow the quotation if a quotation within a sentence does not name the author of the quotation. Thus option D is correct.

What is quotation ?

A quotation is nothing but the repetition of a sentence, phrase, or passage from speech or text, is the representation of an utterance which means something that a speaker actually said is introduced by a quotative marker.

For example, John said: “I saw Mary today” where  oral speech are signaled by addition to quotative markers. In written form the quotations are signaled by quotation marks.

It is also used to present well-known statement  that are explicitly attributed by citation to their original source; it can be used as a literary device to present someone’s point of view.
