Answer:
✏ Arteries are the vessels that carry blood away from the heart to various organs of the body.Since, the blood emerges from the heart under high pressure, the arteries have thick, elastic walls.
The statement that enzymes need to be produced by cells in large quantities because they are consumed by the chemical reactions in which they participate is False.
<h3>
How much quantity of enzyme is needed in a Chemical Reaction?</h3>
- Between 1 and 10,000 substrate molecules can be catalyzed by an enzyme every second.
- Due to the fact that they do not change throughout reactions, enzymes are only found in trace levels in cells. and they have a strong affinity for their substrate.
- By lowering the activation energy and activating more molecules, they act as the catalyst to make the process easier to happen. Because the enzyme must react with the substrate, the concentration of the enzyme is crucial in chemical reactions.
- When enzymes locate their intended substrate, they seize them, undergo a transformation, and then move on to the subsequent substrate molecule.

Answer:
First, third, and fifth are the answers. Glucose is broken down into carbon dioxide and water. Light energy is absorbed by chlorophyll. Energy is used to convert carbon dioxide and water into sugar.
Explanation
Answer:
A. the heterozygote advantage
Explanation:
Heterozygote advantage is the condition where the heterozygous individual has higher relative fitness than both homozygous dominant and homozygous recessive individual. This means that the heterozygote individual has higher chances of surviving than both the homozygous counterparts. Sickle cell anemia is a recessive inherited disorder in which oxygen carrying hemoglobin has an abnormal structure. Hence, the resultant RBCs are not spherical but have crescent sickle shape. The oxygen carrying capacity of such RBCs is drastically reduced but they are unaffected by malarial parasite due to their abnormal structure.
- A person with both the recessive genes for sickle cell would not be able to survive due to insufficient oxygen transport in body.
- A person with both the dominant genes would be free of sickle cell anemia but in case of malaria would not be able to survive as the normal RBCs would be hijacked by the parasite.
- A hetrerozygote would survive both in malaria and sickle cell condition since he has enough normal RBCs for oxygen transport but also has sickle cell RBCs which are unaffected by malarial parasite.
We would know that it was alive if they found bones of it where scientists say it used to live, and if there is no REAL evidence of bones then its a made up animal. I don't know if this helped.... i hope it did.
