Answer:
During fertilization, two gametes from the parents —with different genetic information— join together to obtain a unique offspring, different from the parental cells that gave rise to it.
Explanation:
Gametes are the cells produced by each individual to transmit their genetic information to their offspring.
The process of producing gametes is called gametogenesis, and it is a reductive division called meisois. During meiotic division, crossing over occurs, allowing the recombination of genes, which results in genetic variability.
What makes the offspring different and unique from the parental generation is that, during fertilization, the genetic characteristics of both parents are mixed when two gametes are joined.

Answer: The Adenosine triphosphate is the molecule that provides energy to all the living structures like plants, animals and human beings. Energy is required for all the vital processes of the body.
The ATP molecule consists of three components. The sugar lies at the centre (ribose sugar that is found in the RNA).
Both sides of the sugar is attached by two different components. One side of the sugar is attached by the base(adenine) and the other side of the sugar is attached by the phosphate group.
This phosphate molecule is the most important part for the activity of ATP.
