Answer:
Look below plz :))
Explanation:
1.) In a chemical change, the molecules in the reactants interact to form new substances. In a physical change, like a state change or dissolving, no new substance is formed. Explain that another way to say that no atoms are created or destroyed in a chemical reaction is to say, “Mass is conserved.”
2.) Carbon Dioxide and Water Out: During combustion, the atoms in ethanol and oxygen are rearranged into carbon dioxide and water. The carbon dioxide and water leave the top of the flame.
Estrogen is a hormone in the female reproductive system that can cause the reproductive cycle
Step 1: Pollination
Male gametes are found in pollen, which is carried to female gametes by the wind, water, or wildlife (both insects and animals). Pollen is collected on the stigma of a plant, which is a part of the pistil (the elongated part of a flower extending from the ovary). Pollination is the term for this method.
Step 2: Germination
Pollen tubes begin developing, or germinating, toward the egg cell within minutes. These tubes will provide a pathway for pollen-borne sperm to enter the egg.
Step 3:
The Ovule's Penetration The pollen tubes make their way into the ovule, which houses the female gametes.
Step 4: Fertilization
Pollen tubes carry sperm, which fertilize an egg. An egg and the polar nuclei in the embryonic sac are fertilized in most angiosperms during double fertilization.
