The amount of DNA present in the system of an organism that does not necessarily relate to how complex that certain organism is. There are single-celled microorganism with very few amount of DNA but are very complex with respect to arrangement of certain amino acid component of the DNA strands.
The given blank can be filled with medulla.
The medulla also called the medulla oblongata is the segment of the brainstem that is factually the stem, which elongates from the brain. The medulla is positioned below the pons and above the spinal cord and is a major relay intersection for information conducted to and from the spinal cord and the brain. This section of the brain is a monitoring center for circulation and respiration.
The biogeographic regions that are the most likely to have species that show convergent evolution are Nearctic and Palearctic.
<h3>What are Nearctic and Palearctic?</h3>
The Nearctic and Palearctic are two of the eight (8) biogeographic regions present on the Earth planet.
Palearctic represents (in turn) the most widely extended biogeographic region present on the Earth planet.
Biogeographic regions are specific areas consisting of particular biological (biotic components) features.

The strongest part in an earthquake is the epicenter so it would be option A :)
Answer:
a) the son will not be affected by rickets (0% chance)
b) the daughter will have rickets (100% chance)
Explanation:
Since only the father has rickets and it is a X-linked dominant trait, the mother has two normal X chromosomes. The X chromosome received from the mother by the son will not result in the rickets since the father will have contributed the Y chromosome and that does not have the gene for rickets. In case of the daughter, she will receive the defective X chromosome from her father, which will cause her to have the rickets disease.
Hope that answers the question, have a great day!
