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 <em><u>chances of their survival</u></em> will greatly be affected if the hatching ostriches are of the <em>slow-running type</em>.
Therefore, natural selection may stay in favor of <em>fast-running ostriches</em> to hatch.
for instance in humans, the somatic cells include 46 chromosomes which is the diploid wide variety (2n) and each sperm and egg has 23 chromosomes wherein one of them is the sex chromosome.
