<span>a. an element is a substance that cannot be broken down</span>
Answer: They lack nucleus and other organelles important for the synthesis of the enzyme.
Explanation:
The main function of the red blood cells is to supply oxygen throughout the body. The oxygen binds to the hemoglobin and travels throughout the body to ensure the supply of oxygen to various organs and more precisely the cells of the body.
The enzymes that is being synthesized inside the body is produced by the help of the gene and nucleus along with the other organelles involved in it.The mature red blood cells lack nucleus in order to increase the surface area for carrying the oxygen.
As there is no nucleus, mitochondria and golgi apparatus in the cell, there is no enzyme synthesis and broke down in the cell.
Answer:
B)the energy required
Explanation:
The difference between active and passive transport is in the amount of energy they both require.
- Active transport requires energy to move molecules such as ATP and ions against a concentration gradient.
- Passive transport moves molecules from higher concentration region to one with lower concentration without requiring energy.
Energy is the ability to do work. In passive transport, energy is not used. But in active transport, energy is required.
The polysaccharide is the compound that is unlike wax, saturated fat, and the phospholipid. An example of a polysaccharide is starch.
