The four nitrogen bases contribute to the variation between humans because the order of nucleotides determines phenotypic features associated with genetic inheritance.
- In DNA, there are four types of nucleotides, each containing one different nitrogen base.
- The four nitrogen bases in DNA nucleotides are Adenine, Guanine, Cytosine, and Thymine.
- The linear order of these nucleotides in genes largely determines the phenotypic features associated with genetic inheritance.
In conclusion, the four nitrogen bases contribute to the variation between humans because the order of nucleotides determines phenotypic features associated with genetic inheritance.

Answer:
The Moon is closer than the Sun to Earth.
Explanation:
Answer:
a. two plant species flowering at different times.
Explanation:
<em>The only option that is not a post-zygotic reproductive isolation mechanism would be option a, when two plant species flower at different times.</em>
Post-zygotic reproductive isolation mechanisms are those mechanisms that act to ensure that the product of fertilization remains invalid. This is as opposed to pre-zygotic isolation mechanisms that act to prevent fertilization and hence, formation of zygotes.
In option b, c, d and e; the zygote has been formed already and all the forces are just acting to ensure that it remains invalid. whereas in option a, there is no fertilization yet.
<u>Two plant species flowering at different times will ensure that there is no cross pollination between the two species. Without pollination, there cannot be a zygote formation.</u>
Hence, the correct option is a.
