Is it a, b, c, d ???
OLga [1]

Answer:

I believe that it is D.

Explanation:

If ice caps are melting, and polar bears use the ice flows to get their food, then the polar bears can't use the ice to get food. so, the polar bears most likely are expanding their diets to adapt to their surroundings. So, polar bears are probably moving off the sea ice and eating other foods.

Do you think that aliens exist? Whoever best describes it I will give brainiest
Veseljchak [2.6K]

Answer:

yes.

Explanation:

I believe that some form of life exists outside of our planet. the galaxy is gigantic and ever-expanding. there's a very low chance that with every planet out there, there's no other life form. Now, humans have depicted aliens in many ways. green with black eyes, brown like E.T.... some speak English and some speak a language we cannot understand. I'm not sure if the life forms that are out there would be as developed as we imagine, but anything is possible with an ever-expanding universe. I think the closest we'll ever get to finding an "alien" is a couple of cells that are "alive"

Witch step of cellular respiration will not take place in the absence of oxygen
Over [174]

The answer is; glycolysis

This process converts glucose molecule to pyruvate. It is an oxygen-independent pathway, unlike the Krebs cycle. Glycolysis occurs in the cell cytoplasm while the Krebs cycle (aerobic pathway) occurs in the mitochondria. In the presence of oxygen, the product of glycolysis, i.e pyruvate, is fed to the Krebs cycle.  If oxygen is unavailable the pyruvate is converted to lactate.
