anzhelika [568]

Answer:

DD or Dd

Explanation:

Dimples is the dominant trait (D). Your friend has dimples so that means he or she should have at least one allele of the dominant trait to express that trait. So your friend would either be homozygous dominant (DD) or heterozygous dominant (Dd). Notice that there is a recessive allele in the second. Even with that present, dimples would be still expressed.

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.
