Answer:

1) The Small Intestine. It absorbs most of the nurtients in our food. The circulatory system passes them on to other parts of the body to store or use. Special cells help absorbed nutrients cross the intestinal lining into the bloodstream.

2) The small instestine; although the small intestine is narrower than the large intestine, it is actually the largest section of the digestive system tube, that is measures about 22 feet (or seven meters) on average, or 3 1The /2 times the length of tthe body.

Answer:

50%

Explanation:

Let the allele for red-green color blindness be represented by c.

Normal vision woman whose father is color-blind will be $X^CX^c$

Color-blind male will be $X^cY$

$X^CX^c$ x $X^cY$

Progeny: $X^CX^c, X^CY, X^cX^c, X^cY$ (See the attached image)

Out of the 2 male progeny, 1 is affected for color-blindness while the other is not affected. This gives a 50% probability that a son of the couple will be color-blind.
