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 population of ground squirrels lives in underground burrows several miles from an ocean shore. If a hurricane strikes the shor
Travka [436]

Answer:

flooding

Explanation:

The hurricane brings in enormous amounts of rainfall with it, often resulting in flooding. The ground squirrels in this scenario live relatively close to the ocean shore. They live in burrows, spending big portion of their time in them, as well as having their young ones sheltered in them. The heavy rainfall and the flooding of the area will result in filling the burrows with water. The damage for the population of ground squirrels will be enormous, with their young ones all drowning for sure, and the majority of the adults getting drowned as well, or maybe even all of them. Hope this helps!!!!!
