sometimes, during the dna replication process, mistakes are made. these are called
and they are a main cause of diversity among organisms.

1.mutations
2.translations
3.base pair
4.nucleotides

IT'S MUTATION I TOOK THE TEST ITS RIGHT HOPE THIS HELPED :)

Mutation is the correct answer.

Explanation:

A mutation is a change in the nucleotide sequence of a short region of a genome. Mutations can be spontaneous or they can also be inducted. So, if the mistakes are made during the replication process, the mutations are spontaneous. Due to this, number one is the correct action.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
