Answer:
C. 10 ATP molecules
Explanation:
In the citric acid cycle is a series of eight reactions steps in which a two-carbon molecule, acetyl-CoA, enters the cycle through citrate and two atoms of carbon are removed as two molecules of carbon dioxide.
The energy generated by the complete oxidation of one molecule of acetyl CoA via the citric acid cycle is conserved in the production of three NADH molecules, one FADH₂ and one ATP molecule. Each NADH molecule transfers two electrons to oxygen in the electron transport chain, forming 2.5 ATP molecules each in the process. Similarly, an FADH2 molecules transfers two electrons to oxygen in the electron transport chain yielding 1.5 ATP molecules.
Total ATP molecules produced:
3 NADH + 1 FADH2 + 1 ATP = (2.5 × 3) + (1.5 × 1) + 1 ATP = 10 ATP molecules
Therefore, 10 ATP molecules are generated by the complete oxidation of one molecule of acetyl CoA via the citric acid cycle.
Answer:
Making more babies that will survive and having an adaption
Explanation:
A, b, and c are all correct.
take for example finches off of the galapagos islands. they vary from island to island, yet are still the same bird. on one island they have bigger, more durable and stronger beaks, because that island has many nuts to crack open and eat. on another island, they have thin ling beaks, ideal for pecking at insects in the grass on tree bark. evolution is literally survival of the ifttest, where those equipped best will live and those without means to fight for life will die off, leaving those most capable of reproduction and passing down genes.
Answer: It's known as the continental drift :)
Explanation: "Pangea's existence was first proposed in 1912 by German meteorologist Alfred Wegener as a part of his theory of continental drift. Its name is derived from the Greek pangaia, meaning “all the Earth.”" (copied from google)
