What is one similarity between active and passive transport?
group of answer choices

both involve producing new cells

both involve moving substances against their concentration gradient

both involve moving substances across a membrane

both involve using chemical energy

The correct answer is both involve moving substance across the membrane.

Explanation:

Passive transport is one of the most important membrane transport process which helps in transport of polar molecules and gases along their concentration gradient across the plasma membrane.No addition energy is required to carry out passive transport because during passive transport molecules move from high concentration region to the region of low concentration.

Active transport is a specific type of membrane transport process which helps in the passage of ions against their concentration gradient across the plasma membrane.As the ions are moving against their concentration gradient additional chemical energy is required to carry out their uphill transport.

the answer is d p: cell, q: organ, r: organ system, s: tissue
