Answer:
Although higher levels of testosterone in women cause an increase in muscle mass, this condition is also associated with health problems including, among others, infertility, polycystic ovarian syndrome, hirsutism, sleep apnea, irregular menstrual cycles and obesity, and therefore affecting their athletic performance.
Explanation:
A high level of testosterone in females not only influences their physical appearance, and its imbalance has been associated to health issues that affect women's athletic achievement. Testosterone is a hormone that controls gene expression in multiple organs and one of the most important metabolic regulators of sugar, lipids and proteins, thereby level higher than normal may cause the loss of the organism's homeostasis in women.
 
        
             
        
        
        
Answer:
The correct answer is- Nirenberg and Heinrich, 1961.
Explanation:
Experiments by Marshall Nirenberg and Heinrich Matthaei in 1961, began to decipher genetic codes and state about the 64 triplet codons in the genetic code by using mRNA from DNA to translate into specific amino acids in our biological system.
Their experiment helps to decode or crack the code of DNA by establishing the first codon out of 64 triplet codes which are  UUU codes for phenylalanine. In the future, the same approach is used to find other amino acids.

Answer:
D more active metabolically
Explanation:
As a result of their surface area to volume ratio, smaller living cells are more active metabolically as transport through the cell organelles occur faster
