Carbohydrates, in particular, glucose, are broken down during cellular respiration to produce ATP, carbon dioxide, and water. This process consists of three stages: glycolysis, the citric acid cycle, and electron transport phosphorylation.
During the process of cellular respiration, carbohydrates—specifically glucose, which is a simple sugar—are broken down to produce energy in the form of ATP (adenosine triphosphate). This is a vital process carried out by all living organisms.
This complex process happens in three distinct stages: glycolysis, the citric acid cycle also referred to as the Krebs cycle, and electron transport phosphorylation also known as oxidative phosphorylation.
First, during glycolysis, one molecule of glucose gets broken down into two molecules of pyruvic acid and there is a net output of two ATP molecules. Next, the two molecules of pyruvic acid go through the citric acid cycle where they are oxidized to form carbon dioxide. Finally, during the electron transport chain, electrons are transferred through a series of proteins leading to the creation of water and producing a large amount of ATP.
Overall, the byproducts of this process are carbon dioxide and water, which are released as waste products.

Other hormones come from the thyroid gland, the parathyroid gland, the pituitary gland near the brain, and the brain itself. These hormones control levels of calcium in the blood, energy levels, and ability to grow. They act the same in boys and in girls. Healthy bones need the correct levels of all of these hormones. There are many reasons these hormones can be too high or low, but fortunately they are all uncommon.
Most of these hormones do not become abnormal because of things we can do. Estrogen and testosterone, however, depend on normal body weight. If teenagers do not get enough nutrition and become too thin, then the hormone levels will be too low. The parathryoid hormone also responds to nutrition. Too little calcium causes parathyroid hormone to increase and that will dissolve some of the bone.

I just took the quiz on edge2020
Answer:
B
Explanation:
Answer:
-2 m/s²
Explanation:
Acceleration is the rate of change of velocity:
a = Δv / Δt
In other words, it's the slope of the line on a velocity-time graph. The line at t=3 also goes through the points (2, 4) and (4, 0).
a = (4 m/s − 0 m/s) / (2 s − 4 s)
a = -2 m/s²
1 whole wave is 1 crest and 1 trough.
20 crests and 20 troughs is 20 whole waves.
20 waves / 0.4 seconds = 50 waves per second.
Frequency = 50 Hz
