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.
Large animals with eyes on the sides of their heads(such as horses) have blind spots directly in front of them and directly behind them. They also can't see above their head and back, or below their necks. Hope this helps.
It can affect the environment a little because it is explaining what it can do over the time when the evolution grows

I believe the correct answer would be the parathyroid hormone (PTH) and calcitonin. Both of this hormones work in hand in hand in regulating the phosphate and the calcium levels present in the blood. Hope this answers the question.
Answer:
The correct answer is - less efficient signaling.
Explanation:
Second messengers are the molecules that help in transferring the information in the form of intracellular signal that has come from external stimulus.
Second messenger molecules should be short-lived as the concentration of these molecules should be decreased fastly so the cell can be available for other stimuli mediated by the same second messenger.
With increased lifetime, signaling will be less efficient as another stimulus cannot be detected.
Thus, the correct answer is - less efficient signaling.
