If two parents have dark hair, the child will most likely have dark hair. 
If one has light and the other dark, the child has a 75% chance of having dark hair or a dark-dominated mix because the gene for dark hair is dominant. 
If two parents have light hair, the child will most likely have light hair. 
Of course, it gets a lot more complicated than this, the genes of the child's grandparents and great grandparents could be carried by the parents as well. So if the parents have dark hair but they each have a parent with light hair, the light hair gene will be carried by them and could be passed on to the child. That's how it is with genetic disorders, such as Systic Fibrosis or Sickle Cell Anemia.

Answer:
The correct option is A) will make no difference in the survival of life if there were major changes in the environment.
Explanation:
Due to genetic diversity, variations in species are caused which makes some organisms of a species to be better adapted than other members of the species. These variations cause organisms to survive when differences in the environment occur. Although the allele frequencies might change due to the changes in the environment but the phenomenon of genetic diversity allows life to sustain on earth even when conditions will become unfavourable.  
 
        
             
        
        
        
Answer:
Increase
Explanation:
Visceral fat is a type of storage body fat. It is stored in the abdominal cavity and often surrounds many vital internal organs like stomach and liver. Over the time it forms a layer around these organs and also deposits in arteries which can cause many problems. 
It can lead to insulin resistance which increases the risk for type 2 diabetes. It can also lead to other chronic conditions like heart disease and stroke. Hence, its increased amount is not good for the body. It can be decreased by proper diet, exercise and decreasing stress.
