Answer:
Substitution
Explanation:
There are 3 types of mutations: deletions, insertions, and substitutions.
A deletion deletes one of the bases (AGTC), which can completely mess up the sequence and create a completely different protein.
An insertion inserts a new base into the strand, which can also completely mess up the sequence and create a completely different protein.
A substitution just changes one of the bases to a different base. This doesn't usually affect what protein is made, but when it does, it only changes one of the amino acids in the sequence, whereas the others change all of the amino acids in the sequence.
If the same protein is still created, then this person only experienced a substitution because it didn't affect the end result of the protein.
I believe it's feeding relationships between different organisms
The correct answer is option (a). Parent material
The soil horizon refers to distinct layers of the soils, which are parallel to one another, but have a different composition from the layer present above and below to it.
The soil horizon can be divided into four different layers. First one is organic layer, which is the topmost layer, below this layer second layer of topsoil is present. Below top soil, subsoil is present. Below subsoil, the bottom most horizon parent material is present.
