Which two natural resources will be most affected as people try to meet the growing demand for food?
Jet001 [13]

Answer:

water and land

Explanation:

I assume this is an open-ended question, so you could make an argument for lots of things, but these are the two most important ones in my opinion. The amount of freshwater on Earth is pretty small, only about 2.5%, and most of that is locked in ice. As the demand for food grows, the demand for water for crops and livestock also grows. This is in addition to the increase in water that is needed for a growing population. Climate change increases this problem because of drought. The second most important resource that will be affected is land. If we need more food, we also need space to grow crops and raise livestock. The available space is also reduced because people need places to live and we need to be able to grow trees for wood to build houses and other buildings. I argue that land and water will be the most in-demand commodities as the population continues to increase.

To study the fate of carbon during glycolysis under aerobic conditions, cultured cells are fed with 14C-glucose labeled in vario
kondor19780726 [428]

Answer:

D. The methyl group of acetyl CoA becomes radio-labeled

Explanation:

During the steps in glycolysis, the carbon at position 1, becomes C-1 in dihydroxyacetone phosphate during the cleavage of fructose-1,6-bisphosphate to dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. Subsequently on isomerization of dihydroxyacetone phosphate to glyceraldehyde-3-phosphate, C-1 of dihydroxyacetone phosphate becomes C-3 of glyceraldehyde-3-phosphate.

Furthermore, in pyruvate, the end product of glycolysis, C-3 is converted to a methyl group which then becomes the methyl group in the acetyl-CoA molecule produced from the oxidative decarboxylation of pyruvate.

Since the radioactive 14-C of radio-labeled glucose occupies position 1, it will become the methyl group of acetyl-CoA.
