Explanation:
Unlike asexual reproduction or genetically identical cloning, sexual reproduction involves a sperm and egg and that includes DNA from each parent and since we are humans, we vary and have different traits than another so the baby will inherit some of the parent traits but not all and it makes them unique.

circulate blood throughout the body
Explanation:
That is a function of the circulatory system
Answer:
Water is a covalent compound.
Explanation:
covalent compounds are individual molecules characterized by the sharing of electrons between two or more atoms. Two atoms with similar electronegativity will not exchange an electron from their outermost shell; the atoms instead share electrons so that their valence electron shell is filled.
Example:
Examples of compounds that contain only covalent bonds are methane (CH4), carbon monoxide (CO), Water (H2O) and iodine monobromide (IBr).
Properties:
1. At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas.
2. Covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.
3. Covalent compounds have lower melting and boiling points.
Answer: c. Biofilm
Explanation:
Metabolic cooperation between prokaryotes
allows them to use the resources that they could not use when they are living as single cell. Bio film is the example of the metabolic cooperation.
Bio films are formed by the colonizing of single type of prokaryote such as bacteria and they facilitate the growth of other bacteria on the surface by secreting the substances essential for their growth.
Hence, the correct option is (c) biofilms.
