<em>The correct option is C) Mitochondrial DNA can be traced for generations.</em>
Explanation:
The mitochondria are the organelles of the animal cell which contain their own genome. This genome also has the ability to produce proteins. The mitochondrial DNA passes from the mother to the children and remains identical. We can say that the mother and the children will possess the same mitochondrial DNA. In this manner, the mitochondrial DNA can be traced for generations as it remains the same for generations.
Answer: The structure and curvature of the Earth results in beams of sunlight glancing off the equator and reaching other areas of the Earth. This means that the areas at the equator receive more energy as the sun's rays hit them directly. :)
If the Earths polar Ice melts the ocean levels will increase because of the increased amount of water. Some peninsulas and islands would decrease because they would sink from the risen water.
