Answer:
The correct answer is - a. NADH
Explanation:
The Krebs cycle is a set of chemical reactions that takes place to generate energy from nutrients such as carbohydrates, fats, and proteins converting to carbon dioxide. by oxidation of acetate.
In the Krebs cycle, each molecule of carbon generates 3 molecules of NADH, one molecule of ATP and 2 molecules of FADH2 in each cycle. Thus, the greatest numbers during one turn of the Krebs cycle is NADH.
He did this by experiment with anthrax. Using a microscope, Koch analysed the blood of cows that had failed of anthrax. He marked rod-shaped bacteria and supposed they caused anthrax.
<h3>What does anthrax do to a human?</h3>
Anthrax induces skin, lung, and bowel disease and can be fatal. Anthrax is analysed using bacterial cultures from infected tissues.
There are 04 kinds of anthrax: cutaneous, inhalation, gastrointestinal, and injection.
Anthrax is cured by antibiotics.
Thus, He kept rod-shaped bacteria and supposed they caused anthrax.

the organisms have varying traits, like different colored eggs because of the natural selection.
<h3>What is the process of natural selection? </h3>
Natural selection is one of the main mechanisms of evolution. In a very simple way, we can say that natural selection is a process in which the fittest organisms are selected, survive in the environment, reproduce and pass their characteristics on to their descendants.
the color change of an egg occurs by natural selection and also by genetic variability. since the environment will select the best ones to survive and mutations will occur. Natural selection will forcefully change the environment causing only a few species to survive.
