Answer:
Molecule A is a simple sugar or amino acid, while molecule B is a starch or protein.
Explanation:
Molecule A, as a simple sugar or amino acid, consists of small molecules which can readily pass through the cell membrane, while Molecule B, as a starch or protein, consists of large molecules, thus, can't pass across the cell membrane.
This is the reason why the cell membrane is considered to be selectively permeable.
Answer:
Water and Oxygen should be swapped.
Explanation:
The correct order should be:
Oxygen + Glucose --- becomes --- Carbon Dioxide + Water + Energy
Oxygen and Glucose react to become Carbon Dioxide and Water, providing energy in the process.
The chemical equation is:
C6H12O6 + 6O2 = 6CO2 + 6H2O + Energy
For each molecule of Glucose, C6H12O6, it takes 6 Oxygen atoms, or three pairs, to combine with the Glucose. The results are 6 molecules of CO2 and 6 molecules of H2O. The result is that energy is released, transferred.
After 12 hours without eating, Seth is very hungry. It is likely that Seth's blood glucose level is LOW and his blood insulin level is HIGH.
A situation in which the blood glucose level is low is called hypoglycemia. In this situation, the level of glucose in the blood is much more lower than the normal level. This may be caused by a lot of factors. When the blood glucose level is low, the glucagon hormone mobilize the liver to release glycogen which is converted to glucose. The presence of glucose in the blood increase the level of insulin secretion which in turn increased the feeling of hunger in the individual.
First you determine the total mass of the strawberries used
Then determine the mass of the DNA obtained from the strawberries
percentage mass is therefore equal to mass of the DNA obtained divided by total mass strawberries multipy by a 100
