By which process are fossil fuels formed?
Delvig [45]
There are three major forms of fossil fuels and these are coal, oil and natural gas. All three were formed many millions of years ago before the time of dinosaurs. Plants and trees died and sank to the bottom of swamps which filled the land. The dead matter formed layers of a spongy material called peat. Over time the peat was covered by sand, clay and other minerals which turned into sedimentary rock. As the layers of rock piled up, their weight squeezed the peat until water came out of it and it eventually turned into coal, oil and natural gas.

Explain why increased ecosystem diversity contribute to increased biodiversity in the biosphere
Leto [7]

Answer: Diversity, referring to the state of having many different organisms cohabitate within an area is a desirable outcome for many ecosystems. The presence of a wide spectrum of different organisms allows for more life to be able to thrive in an ecosystem. For example, an ecosystem with a wide array of shrubs, grasslands and forested areas is able to accommodate more life forms than an ecosystem of just forest. This increased capacity to support life directly improves the capacity of the biosphere to support life as well, diversity leading to growth.

Glucose labeled with 14C in C-3 and C-4 is completely converted to acetyl-CoA via glycolysis and the pyruvate dehydrogenase comp
Morgarella [4.7K]

Answer:

The correct answer is option d.

Explanation:

The production of Acetyl-CoA takes place by the dissociation of both carbohydrates and lipids in the process of glycolysis and beta-oxidation. It then moves into the TCA cycle in the mitochondria and combines with oxaloacetate to give rise to citrate.  

In the given case, no labeling will be found in the acetyl-CoA. The labeled C3 and C4 carbon of glucose signify the carboxyl carbon of pyruvate. In the succeeding reactions of the transformation of pyruvate to acetyl-CoA, the carboxyl carbon gets lost in the form of carbon dioxide. Thus, acetyl-CoA does not comprise any labeled C3 and C4 of glucose.
