The cells that decides how thw plant take shape and function is the meristem cells
The answer is true I’m pretty sure
Well during an enzyme catalyzed reaction the enzyme bonds with a specific substrate at the active site. This is called an enzyme-substrate complex. The substrate is converted into a specific product, but the enzyme remains unchanged. Enzymes accelerate reactions by factors of at least a million.Enzymes are not used up in a chemical reaction. Usually, the enzyme will "reset" and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction. Initially, the enzyme has a particular shape. Something happens to the enzyme (usually a shape change, called a conformation change, brought on by the presence of two or more chemical reactants), and the enzyme catalyzes the reaction. After the reaction is catalyzed, the product is released, and the enzyme can "relax." This means it goes back to its normal shape, ready to do it all over again
Hope it helps

Explanation:
Marie Curie died of aplastic anemia in 1934. Aplastic anemia is an autoimmune disease in which the body fails to produce blood cells in sufficient numbers. Blood cells are produced in the bone marrow by stem cells that reside there. Aplastic anaemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets.
Fatigue is a symptom of aplastic anemia as the blood doesn't have the necesarry red blood cells to transport the oxygen to the organs.
Rapid heart rate happens because the body senses the decrease of oxygen's concentration and the hearts beats faster to provide the organs of oxygen.
Pale skin happens because the blood vessels are contracted in order to provide oxygen to the important organs of the body as the brain and heart. It means that less blood reaches the face and it shows as pale skin.
Prolonged bleeding from cuts happens because there aren't enough platalets to produce a blood clot to stop the bleeding.
Dizziness happens because there is not enough oxygen arriving to the brain.
If she is A negative, she can only receive blood from others A negative donors, or O- donors. This is because she has antibodies to B, and to groups that have the protein Rh (+). So she can't receive blood either B nor Rh+.
