Answer:
Explanation:
The bloodstream carries glucose-a type of sugar produced from the digestion of carbohydrates and other foods-to provide energy to cells throughout the body. Unused glucose is stored mainly in the liver as glycogen.
Insulin , glucagon, and other hormone levels rise and fall to keep blood sugar in a normal range. Too little or too much of these hormones can cause blood sugar levels to fall too low (hypoglycemia) or rise too high (hyperglycemia).
Normally, blood glucose levels increase after you eat a meal. When blood sugar rises, cells in the pancreas release insulin, causing the body to absorb glucose from the blood and lowering the blood sugar level to normal. When blood sugar drops too low, the level of insulin declines and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels back up to normal
Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.

Answer:
Hydrophobic Properties
Explanation:
Lipids and water do not mix. The contents of cells in the larger proportion is the cytoplasm, this is made up mostly of water. The lipids serve as a barrier; the contents that are distributed in a watery medium will not be able to mix. This is due to the hydro-phobic or water "hating" capacity of lipids.
<span>Which of the following is true of all greenhouse gases?
</span>
C. THEY TRAP ENERGY IN THE ATMOSPHERE.
They are not naturally occurring. They are the result of human activity like using electricity, burning fuel, etc.
They don't exist in fixed quantities and they don't reflect incoming radiation. The volume of greenhouse gases emitted depends on the activity done. It also does not stay in one place, it moves around and combines with other green house gases; trapping heat in the atmosphere and making the Earth warmer.
