Explain how scientists think about fitness
nikitadnepr [17]

Answer:

Scientists believe that fitness is not only the ability to have physical fitness but it also refers to the adaptations that make an organism survive in its environment.

According to biological studies, biologists believe that the ability of an organism to survive in a particular area and to pass on its characteristics to its offspring is fitness.

The health scientists define fitness as the ability of an individual to be physically fit and to move without pain.

The scientists which study psychology believe that fitness is the well functioning of a person;s body as well as his/her mind.

Describe the four structural roles of the skeletal system.<br> The Human SKELETAL SYSTEM
makkiz [27]

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.
