In ostriches, there are 2 types: ones that run fast and those that run slowly. The fast birds can reach up to 40 miles an hour.

liraira [26]

Answer:

Natural selection will select the type of ostriches that can run up to 40 mph.

Explanation:

According to the theory of natural selection, organisms with favorable traits following their environment are more likely to reproduce. In doing so, they pass on the better traits to their next generation for the survival of their species.

This process allows organisms to adapt to their environment. And the survival of species is assured.

Here, the type of ostriches that run slow probably fall prey to the jackals. To maintain survival, the ostriches reproduce and lay eggs. If out of almost a dozen eggs, one or two are left to hatch than the chances of their survival will greatly be affected if the hatching ostriches are of the slow-running type.

Therefore, natural selection may stay in favor of fast-running ostriches to hatch.

Use the original DNA sequence above to write an example of each of the following types of mutations: insertion, substitution, an

Tanya [424]

For example: GGATACCTAGGTAAT

Insertion: GGATGACCTAGGTAAT

a nucleotide that was not present before is inserted into the original sequence

Substitution: CGATACCTAGGTAAT

the first nucleotide was substituted in for another (C for G)

Frameshift (basically a insertion or deletion, we'll try deletion here): GATACCTAGGTAAT

the first nucleotide was deleted, causing the reading frame to be shifted (instead of GGA as the first codon, we have GAT)
