Answer:
vestigial structure that is C
Step 1: Glycolysis. In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule. In these reactions, ATP is made, and \text{NAD}^+NAD + N, A, D, superscript is converted to {NADH}NADHN, A, D, H.
Step 2:Pyruvate oxidation. Each pyruvate from glycolysis goes into the mitochondrial matrix—the innermost compartment of mitochondria. There, it’s converted into a two-carbon molecule bound to Co-enzyme A, known as acetyl CoA. Carbon dioxide is released and NADH is generated.
Step 3:Citric acid cycle. The acetyl CoA made in the last step combines with a four carbon molecule and goes through a cycle or reaction, ultimately regenerating the four carbon starting molecule.
Answer:
Epithelial cells also line the inside of your throat, intestines, blood vessels, and all your organs. They are a barrier between the inside and outside of your body and are often the first place that is attacked by viruses as they begin their invasion deeper into the body.
Explanation:
Epithelial tissue covers the outside of the body and lines organs, vessels (blood and lymph), and cavities. Epithelial cells form the thin layer of cells known as the endothelium, which is contiguous with the inner tissue lining of organs such as the brain, lungs, skin, and heart.

Which two mineral samples would be most
difficult to distinguish from each other based on
their color, luster, and streak?
diamond
Talc is the softest and diamond is the hardest. Each mineral can scratch only those below it on the scale.
