What is the main way that active transport differs from diffusion?

Active transport is different from diffusion because it requires energy expenditure, while diffusion requires no energy at all. In diffusion, materials are moving from areas of high concentration across the cell membrane into areas of low concentration. This requires no energy on the part of the cell. In active transport, however, the cell is moving material between two areas of equal concentration, or from an area of low concentration into an area of high concentration. This requires the cell to expend energy.

As powerful as diffusion is, cells sometimes must move materials in the opposite direction—against a concentration difference. This is accomplished by a process known as active transport. As its name implies, active transport requires energy.

please mark as brainliest it would really help because i only need one more to move up a rank <3

konstantin123 [22]

Yes, because each of the four nucleotide bases present in DNA have a corresponding base: adenine bases always pair with thymine bases, and cytosine bases always pair with guanine bases. For example, if one strand of a DNA molecule was CTAGGT, the sequence of the second strand would be, from left to right, GATCCA.

Answer:

The typical state of a neuron is the resting potential, but when electrical signals stimulate it to its threshold, the action potential is immediately observed.

Explanation:

The capacity for rest shows what occurs when a neuron is at rest. A capacity for action takes place when a neuron passes information down an axon, far from the cell body. When depolarization exceeds approximately -55 mV a neuron can activate the capacity for action.

Sodium-potassium valves start moving two potassium ions within the cell as three sodium ions are poured out to keep the negatively charged membrane within the cell; this keeps the resting potential in place.
