Answer:
An egg placed in salt water will float!
Explanation:
In normal tap water, an egg will sink because it's density is greater than the density of water. But, when salt is added to the water, it's density becomes greater than the egg's density. The term used to describe this is "buoyancy."
Answer:
C. The upper part of the water column represents areas of high sunlight penetration.
Explanation:
I just took the test and checked my answers.
Global winds are winds that appear in belts that go all around the world. Like local winds, global winds are driven by unequal heating of the atmosphere. Since global winds blow west to east, it helps humans travel west to east.
<h3>How global winds influence climate?</h3>
Global wind belts and calm regions have an effect on, is that the berg winds blow from the east and die out as they are available close to the equator.
The westerlies blow from the west and move storms across u. s. The easterlies blow from the east and they cause stormy weather to occur once cold air forms this belt meets heat air of the westerlies.
Thus, this could be the answer.

Let me know if i'm wrong.:)
Answer:
a. Acetyl CoA carboxylase
Explanation:
Much of the fatty acids used by the body is supplied by the diet, excessive amounts of carbohydrates and protein obtained from the diet can be converted to fatty acids and stored as triglycerides. Fatty acid synthesis occurs mainly in the liver and mammary glands, and to a lesser extent in adipose tissue and kidney, the process incorporates acetyl CoA carbons into the forming fatty acid chain using ATP and NADPH.
The acetyl portion of acetyl CoA is transported to cytosol as citrate, produced by condensation of oxaloacetate and acetyl CoA, the first reaction of the citric acid cycle, this occurs when the concentration of mitochondrial citrate is high, observed when there is a high concentration of ATP and isocitrate dehydrogenase is inhibited. The increase of citrate and ATP favors the synthesis of fatty acids, since this pathway needs both. Acetyl CoA should be converted to malonyl CoA. Carboxylation is catalyzed by acetyl CoA carboxylase and requires ATP, this reaction is the regulated step in fatty acid synthesis: it is inactivated by products, malonyl CoA and palmitoyl CoA, and activated by citrate, another regulatory mechanism is reversible phosphorylation of enzyme, which makes it inactive due to the presence of adrenaline / glucagon
