The answer to this is : B, Their roots.
Answer:
Approximately 20,500 genes
Explanation:
The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.
The skeletal muscles are considered voluntary muscles and are mostly located in all parts of the human body. Therefore, these are the muscles that are attached to the bones and have an origin but are NOT highly branched. The skeletal muscles are the UNBRANCHED ones whereas, it is the cardiac muscles that are considered branched.
