Explanation:
The molecule is the smallest unit of the substance that retains its characteristic properties. The macromolecule is such a unit but is considerably larger than the ordinary molecule, which usually has a diameter of less than 10 angstroms (10−6 mm).
it’s c Ik but ya wanna have to do that
Answer:
All the possible alleles for a gene with multiple alleles cannot be expressed by single individual
Explanation:
Gene pool refers to the sum total of all the alleles of all the genes which are present in a population. Human beings are diploid organisms. One individual can have only two possible alleles for a gene. A gene can have two or more than two alleles. Since all the possible alleles for a gene with multiple alleles cannot be expressed by single individual, a gene pool cannot be made of one individual.
Anabolism creates molecules the body needs for functionality and it uses energy in the process. Catabolism, on the other hand, breaks down complex molecules and releases energy which is available for the body to use
Answer:
<h2>
D. oxidation-reduction reaction
</h2>
Explanation:
1. Oxidation-reduction reaction: An oxidation-reduction reaction (also known simply as redox reaction) is one of the type of chemical reaction, it involves a transfer of electrons between two species.
2. In plants light is absorbed by chlorophyll which causes transfer of electron from water, and the final acceptor of electron is oxygen.
3.Plants takes carbohydrates from environment and water from earth, and with the help of sun-light they make carbohydrates and oxygen, so they are called autotrophs.
