Which of the following is a correct difference between active transport and facilitated diffusion?
sweet-ann [11.9K]

Answer:

Active transport requires energy from ATP while facilitated diffusion does not

Explanation:

Active transport and facilitated diffusion with the use of channel and carrier proteins are both ways by which ions, polar and large molecules cross a selectively permeable membrane.

The major difference is that; Active transport transport these particles from a low to high concentration, which is against concentration gradient and hence, energy is required to perform the task

Facilitated diffusion transport from a high to low concentration, which is through a concentration gradient and hence, no energy is required to perform the task.

A tail like structures which allows certain unicellular organisms to move
yaroslaw [1]
The answer is flagella.

Flagella are tail-like structures which allow some unicellular organisms to move. Although their primary function is in locomotion, they can also serve as sensory organelles that are sensitive to chemicals or temperature of the environment. They can be found in all three domains - bacteria, archaea, and eukaryota:
- Bacterial flagella have a rotary motor at the base of each filament turning clockwise or counterclockwise
- Archaeal flagella look like bacterial flagella.
- Eukaryotic flagella are structurally complex cellular projections.
