Which of the following is altered during a chemical reaction? a. the number of atoms b. the amount of energy conserved c. the chemical bonds between atoms d. the types of elements involved in the reation

Option (C) is the chemical reaction.

Explanation:

A chemical reaction is defined as the reaction which leads to the formation of a new compound or substance due to exchange of valence electrons of the reactants.

For example,

Here, sodium donates its one valence electron to a chlorine atom in order to become stable. Therefore, an ionic bond is formed and a new compound NaCl is formed as a result of this chemical reaction.

Whereas number of atoms and elements involved in a chemical reaction remains the same.

Thus, we can conclude that the chemical bonds between atoms is altered during a chemical reaction.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
