What is a major difference between facilitated diffusion and active transport?

Biology
1 answer:
siniylev [52]3 years ago
7 0

Answer:

The correct answer is Active transport moves substances against the concentration gradient.

Explanation:

The principle difference between active transport and facilitated diffusion is that active transport helps in the movement of various substances in the uphill direction which means against the concentration gradient.

    In simple words active transport helps in the movement of substance from the region of low concentration to a region of high concentration.

On the other hand during facilitated diffusion substances move along their concentration gradient which means from the high concentration region to the region of low concentration until the concentration of both sides become same.

Processes such as changes in orbital geometry or volcanic eruptions have clearly affected climate in the past, and these explain
docker41 [41]

Answer:

TRUE

Explanation:

There has been a constant increase in the earth's global surface temperature. This global rise in temperature is due to the increasing number of volcanic eruptions on earth's surface, changes in the orbital geometry as well as due to the introduction of the industrial revolution, that has been taking place on earth for the last 200 years.

The eruption of volcanoes leads to the release of a large number of pyroclastic materials and greenhouse gases and volcanic gases such as CO₂, SO₂, H₂O, H₂S and many other gases, which is harmful to the atmosphere. This leads to an increasing amount of temperature, resulting in the melting of the glaciers in the polar region.

Over this long time, plate motions have rapidly taken place, due to which the volcanoes were formed and erupted near the convergent and the divergent plate boundaries.

Thus, the above-given statement is true.
