Well there really isn't an age limit, sometimes the parents don't want you to date but you can date at any age really, Most people I know started dating when they were 9 to 10 years old. I hope this helps and if you have any more questions, Feel free to ask.
Yes. For example every tree that is cut down you can plant a tree so the tree will grow back.
ANSWER FOR QUESTION 1:
The most common type of E. coli infection that causes illness in people is called E. coli O157, which produces a toxin known as Shiga-toxin. Shiga-toxin producing E. coli is abbreviated as STEC. Symptoms of infection with this germ include watery or bloody diarrhea, fever, abdominal cramps, nausea, and vomiting.
ANSWER FOR QUESTION 2:
Some other germs don’t cause as many illnesses, but when they do, the illnesses are more likely to lead to hospitalization. Those germs include: Anyone can get sick from eating contaminated food. Follow four simple food safety steps —clean, separate, cook, and chill—to lower your chance of food poisoning and to protect yourself and your loved ones.
Answer:
Monomer: 2 - Amino acid
3 -Nucleotide
Polymer: 1 - Cellulose
3 - Nucleic acids
Example: 1 - Carbohydrates
2 - Collagen
Function 1: Carbohydrates are a source of energy in the body.
Function 2: Collagen is the most abundant protein in the human body. It's a long, fibrous structural protein that supports tissues and gives structure to individual cells. Collagen fibers are tough and found in bundles. They providing tensile strength to the tissues containing them.
Function 3: DNA is a protein structure that carries instructions needed for an organism to develop, survive and reproduce. It is a nucleic acid that contains the genetic instructions for the development and function of living things, its main role is the long-term storage of information
Explanation:
Monomers are single molecules that can bond with identical molecules to form polymers.
1. Glucose can combine with other glucose molecules to form starch or cellulose which results in formation of carbohydrates.
Carbohydrates are a source of energy in the body.
2. Amino acids can combine with other amino acids to form a protein chain which results in formation of collagen
Collagen is the most abundant protein in the human body. It's a long, fibrous structural protein that supports tissues and gives structure to individual cells. Collagen fibers are tough and found in bundles. They providing tensile strength to the tissues containing them.
3. Nucleotides can combine to form nucleic acids resulting in formation of enzymes.

Cross-pollination, or when pollen from one plant fertilizes another plant of the same produces outcrossing or outbreeding.
Explanation:
Cross pollination is the transfer of pollen from a plant's stamen to a different plant's stigma of the same species. They produces stronger plants. For example only pollen from a daisy can pollinate another daisy.
They have male and female reproductive units on separate plant. If they are on the same plant he pollen will not fertilize the female reproductive unit on the plant.
This process needs four steps pollination, germination, penetration of the ovule and fertilization. The Zygote divides to form an embryo after fertilization.
