Answer:
A few of the positive particles aimed at a gold foil.
Answer:
Parentals: PP (purple) and pp (white)
F1: Pp (purple)
Explanation:
When the two parental plants of differing phenotypes (purple or white flowers) cross, the F1 is 100% purple. This result suggests that the parentals were true breeding (homozygous), with purple flowers being the dominant allele.
When the F1 self pollinates, the F2 shows proportions very similar to 3/4 purple and 1/4 white (401/532 ≅ 3/4 and 131/532 ≅ 1/4). The 3:1 phenotypic ratio is typical of the offspring resulting from a cross between two heterozygous individuals.
The results make sense if the genotypes of the different generations are:
Parentals: PP (purple) X pp (white)
F1: Pp (purple)
F2: 1/4 PP, 2/4 Pp, 1/4 pp
Answer:
The pulmonary artery carries deoxygenated blood (blood whose oxygen content is relatively low) from the right ventricle to the lungs. The blood here passes through capillaries to alveoli and becomes oxygenated (as part of the process of respiration).
