Answer:

7. D

8. D

Explanation:

7. One of the most important functions of iron is the transportation of oxygen to the blood. Iron’s main purpose is to carry oxygen in the hemoglobin of red blood cells throughout your body so your cells can produce energy.

8. A network of tiny capillaries connects the arteries and veins. Though tiny, the capillaries are one of the most important parts of the circulatory system because it’s through them that nutrients and oxygen are delivered to the cells.

Punnett Squares are used by geneticists to determine the likely genotypes of the offspring of two parents.
PilotLPTM [1.2K]
That's correct - it's a square where on one axis, the paternal allele (allele = one of the possible forms of the same gene), and on another the maternal allele is listed. Often, it's also indicated whether an allele is recessive or dominant.

Then, in the table that results, all the possible "combinations" of allele between the paternal and maternal party are created. If you count how often a certain combination appears, it indicates the likelihood of that combination.
See the picture (though it is directly from Wikipedia, please note). The likelihood of BB is 25%, of Bb is 50%, and of bb 25%.
