Answer:
<em>What are three measures of life variations?</em>
<em>Species diversity, genetic diversity, ecosystem diversity</em>
Explanation:
<em>Biodiversity</em>
<em>The amount of biological or living diversity per unit area. It includes the concepts of species diversity, habitat diversity and genetic diversity.</em>

The answer to this is most certainly not A or C, so you can rule those out. If you look at DNA, every persons has different nitrogenous bases (<span>adenine (A),guanine (G), thymine (T), and cytosine (C))
This means the answer to your questions is #2, DNA.

The molecules used and produced in the Kreb cycle as depicted by a and b respectively are:
- a. pyruvate
- b. ATP, FADH2, NADH
<h3>What is kreb cycle?</h3>
Kreb cycle, also called tricarboxylic acid cycle, is a series of enzymatic reactions that occurs in all aerobic organisms.
The Kreb cycle involves the oxidative metabolism of acetyl units, and serves as the main source of cellular energy.
Kreb cycle makes use of pyruvate as reactant and produces ATP, NADPH, FADH2 as products.

The correct option is C.
Fermentation is the metabolic process which involves the break down of sugar in the absence of oxygen to produced gases, organic acids or alcohols. Fermentation can only occur in the absence of oxygen. Fermentation generates much less ATP than cellular respiration. There are two types of fermentation, alcoholic and lactic acid fermentation; lactic fermentation does not produce carbon dioxide. During the process of fermentation, NAD+ is always generated from NADH by the transfer of electron to pyruvate or a derivative, thus, fermentation makes NAD+ to keep glycolysis going.
