Answer: E). Acetate enters the citric acid cycle and joins a four-carbon acceptor molecule to form citrate.
Explanation: Acetyl CoA enters the citric acid cycle and combines with oxaloacete (a four carbon acceptor molecule) to form citrate. Citric acid cycle is a cycle of eight enzyme catalyzed reactions in which acetyl CoA from pyruvate is oxidized to generate ATP/GTP, NADH and FADH2. Decarboxylation occurs in citric acid cycle at two steps catalyzed by isocitrate dehydrogenase and alpha ketoglutarate dehydrogenase complex. Substrate level phosphorylation occurs at the step catalyzed by succinyl CoA synthase in which GTP is produced from addition of a phosphoryl group to ADP.
Answer:
Sowbugs and pillbugs are similar in appearance and their names are sometimes used interchangeably. However, the sowbug has a pair of tail-like appendages which project out from the rear of its body, while the pillbug has no extreme posterior appendages, and can roll up into a tight ball when disturbed.

Answer:
Ocean trenches are formed when the denser oceanic plates sink.
Explanation:
In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.
