Mitochondrial DNA mutation occurs at a constant rate throughout history. Thus, each different base in Mitochondrial DNA is able to show just how long ago the 2 species diverged from each other.

From the moment a bite of food enters the mouth, each morsel of nutrition within starts to be broken down for use by the body. So begins the process of metabolism, the series of chemical reactions that transform food into components that can be used for the body's basic processes. Proteins, carbohydrates, and fats move along intersecting sets of metabolic pathways that are unique to each major nutrient. Fundamentally—if all three nutrients are abundant in the diet—carbohydrates and fats will be used primarily for energy while proteins provide the raw materials for making hormones, muscle, and other essential biological equipment. Carbohydrates, on the other hand, can only be stored in limited quantities, so the body is eager to use them for energy. "We think of carbs as the [nutrient] that's used first,"<span>The carbohydrates in food are digested into small pieces—either glucose or a sugar that is easily converted to glucose—that can be absorbed through the small intestine's walls. After a quick stop in the liver, glucose enters the circulatory system, causing blood glucose levels to rise. The body's cells gobble up this mealtime bounty of glucose more readily than fat, </span>
Answer:
Our eyes can trick our brain in some manner. When the eye see an image, our brain assumes that the image being seen is a image which had been seen in the past. Therefore, our brain is tricked into believing that the image which is being seen is of something which has been visualized before whereas in actual it is a new image. Hence, this is the relationship between seeing of the eyes and perceiving of the brain.
