Answer:
D, think of chemical changes. When iron rusts it is chemically changed. The other answers are a change in form or a property of iron.
They hold DNA( hope this helps)
The reduced coenzymes generated by the citric acid cycle donate electrons in a series of reactions called the electron transport chain. The answers are as;
a) 1. NADH and 7. FADH2
b) 6. O2
c) 3. NAD+, 1. H2O, 4. ATP and 8. FAD
Oxygen is the ultimate electron acceptor, and it combines with hydrogen ions to produce H2O. This process occurs at the conclusion of the electron transport process.
ATP molecules, which are carriers of energy, would be the final outcome of the oxidative phosphorylation process.
(a) NADH and FADH2 donate electrons to the electron transport chain.
(b) O2 is the final electron acceptor.
(c) NAD+, H2O, ATP, and FAD are the final products of the electron transport chain and oxidative phosphorylation.

A researcher was studying mutations in bacteria. He found that certain bacteria had changes in their DNA that allowed them to be resistant to antibiotics. This research is an example of <u>evolutionary genetics.</u> The mutation will lead to <u>all the bacteria becoming resistant to the antibiotic.</u><u> </u>
Genetic evolution :
Evolutionary genetics examines the relationship between genetic variation and evolutionary change. As a result of the recent expansion in the availability of whole genome sequence data, large amounts of genetic data are being produced at an increasing rate, making programming an indispensable tool for researchers.
The spread of antibiotic resistance among pathogenic bacteria is a straightforward and elegant example of adaptation through natural selection. Through mutations that alter the biological targets of antibiotics or by obtaining resistance genes from other bacteria, microorganisms can develop resistance to antibiotics.
