Answer:
A
Explanation:
There is no much more to say than the letter A describes the process of facilitated diffusion.
The normal diffusion ocurres when the solute passes the membrane through the space of the double layer of phospholipids. Particles that are small and apolar can pass trough the membrane without problems.
For bigger or polar particles we need to use a protein system to help them pass into the cytoplasm. That's what we call Facilitated Difusion.
About the other options:
B) That's the explanation about active transport. That happen for every particle who is going against the gradient of concentration.
C) Again: if we are talking about diffusion, there is no energy needed.
D) The Water Molecules suffer the process os osmotic pressure. Water deslocates to the higher gradient of concentration - contraty what the other particles do.

Most of the increase in global temperatures since 1950 has been caused by human activity.
The United States is the second largest contributor to carbon dioxide (CO2) in our atmosphere
As global temperatures increase, our societies will find it harder to adapt to the changes this brings, and some species are more likely to go extinct
The concentration of carbon dioxide (CO2) in our atmosphere, as of May 2020, is the highest it has been in human history.
NASA data show that average global temperatures in 2019 were 1.8 degrees F (0.98 degrees C) warmer than the 20th century average. In fact, the five warmest years in the 1880–2019 record have all occurred since 2015
Global warming puts coral reefs in danger as the ocean warms, scientist fear that coral reefs will not be able to adapt quickly enough to the resulting changing conditions, and bleaching incidents and diseases will increase
Answer:
Active Transport and Passive Transport are similar because then both have nutrients, oxygen, water, and other essential molecules to the cells along with the elimination of waste products.
I would say d, based on the fact matter cannot be created nor destroyed
Answer:
All of the above
Explanation:
ATP synthase is a transmembrane protein enzyme. It harnesses the potential energy –proton motive force- created by the development of a proton gradient across a membrane (could be across the intermembrane space in chloroplast and mitochondria). As the H+ ions 'drain' back and pass through their channels in the protein enzyme, the synthase is able to phosphorylate ADP and Pi to form ATP.
These ATPs (from photophosporylation) in light-dependent phase, are used in the catabolism of glucose, in the light-indepedent phase.
