Answer:
Glucagon signals the liver to start producing glucose.
Explanation:
Glucagon signals the liver to start producing glucose from the breakdown of amino acids through gluconeogenesis process. When the glucose level decreases in the body due to fasting or starvation, the pancreas release glucagon which provides signals to the liver to produce glucose form non carbohydrates substances present in our body. This production of glucose increases the concentration of glucose in the blood and the body used this glucose for the generation of energy molecules in the form of ATP.
<span>Factors that can increase mutation rates are high and low temperatures, food additives, and UV rays. All of these answers are correct. Mutation rates in genes vary depending on many environmental effects. UV rays, along with varying temperatures, can cause mutations during cell division due to the damage they impart on the cells that are dividing. Dangerous food additives are believed to cause mutations, as seen in animal studies (ie. aspartame causing cancer in rats).</span>
Answer:
<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.
C. There is a lack of nutrients
Modern H. sapiens differ from the archaic form in that moderns have a high, vertical forehead, a mental eminene; and lack occipital bun. Modern homo sapiens have distinguishing features such as they have a short base, a high braincase, back of the skull is rounded and indicates a reduction in the neck muscles, face is reasonably small with a projecting nose bone among other features that makes them different from the other sapiens.
