Below is a segment of a strand of normal DNA:
ATA GCA TGA
If the DNA sequences changes to:
AAT AGC ATGA
this would be an example of
an insertion mutation
a homozygous mutation
a deletion mutation
Natural Selection

Insertion

Explanation:

this would be insertion because in the first part another A is added which is the cause for there being an extra part at the end and the new A in the first part

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
