Hardy and Weinberg’s work determining how allele frequency changes (C)
DNA supercoiling means under or over winding of the DNA strand and basically is to become more condensed and more organized. Supercoiling is very important as it compacts the genetic code and as if that was not enough supercoiling also regulates and oversees the access the the genetic code.
Answer:
1. Support
2. Protection
3. Movement
4. Supply & Storage
Explanation:
1. Support : It provides a framework to support the organs and tissues of the body.
2. Protection: It protects our internal organs. The skull protects the brain; the thorax (sternum, ribs and spine) protects the heart, lungs and other viscera (organs within the thorax).
3. Movement: It provides a framework for muscles to attach. Then when the muscles contract they pull on the bones of the skeleton, which act like levers to create movement.
4. Supply & Storage: The bones that make up the skeleton are a source of both red blood cells (which transport oxygen) and white blood cells (which fight infection), which are formed within the bone marrow.
Answer:
The activity factor was modified. Ambulating indicates that the person is active. Even small activities require energy. So, people who can walk around and aren’t bedridden expend more calories than people who need to be on bedrest all day. Also, when the stress factor was changed to severe infection, the caloric requirement increased. This increase is probably because the immune system requires more energy to fight off the infection
