Nuclear DNA is present in the nucleus of eukaryotic cells. When working with the DNA samples, the best source of nuclear DNA is hair root that anchors the whole shaft of hair. Hair root possesses cells that are called as keratinocytes.
Answer:
platelets
Explanation:
platelets clot to plug the holes in the blood vessels and stop the bleeding . if the blood doesn't clot it means there is a low amount of platelets
Answer:
it regulates the calcium levels in the blood
Explanation:
Anemia is a medical condition in which there is a decrease int the total amount of red blood cells in the blood and it always results in lowered ability of the blood to carry oxygen. Vitamin B12 is needed to make red blood cells and lack of Vitamin B12 can lead to aneamia. So, the vitamin that is most associated with aneamia condition is VITAMIN B12.
Though I cannot write this essay for you, I can provide some information to get you started on the relationship between ancestry and evolution.
<h3 /><h3>How are ancestry and evolution related?</h3>
Ancestry and evolution share a close relationship in that we can use one to learn about the other. Evolution can be <u>traced </u>using ancestry. By analyzing the genetic information of ancestral species and using information gathered about the environment in which they lived, we can deduce the impact of evolution on said species. One possible example is that penguins used to be capable of flight, but given their mostly aquatic environments, have evolved wings more suited for swimming, and lost the ability to fly as a result.
Therefore, we can say that ancestry and genetic information can be used to support the theory of evolution by examining how two species can be very different but share a common ancestor, and evolution can explain these changes.
