Answer:
The lungs are made of a soft, elastic, spongy tissue.The large numbers of blood capillaries and rich blood supply gives the lungs their pink colour.
The lungs are pink because they are filled with oxygenated blood that has a pinkish hue due to the presence of oxygen-bound hemoglobin.
The lungs are made up of millions of tiny air sacs called alveoli, which are surrounded by blood vessels called capillaries. These capillaries contain oxygenated blood that has been pumped from the heart. When oxygen from the inhaled air enters the alveoli, it diffuses across the thin walls of the alveoli and into the capillaries. At the same time, carbon dioxide, a waste product, diffuses from the capillaries into the alveoli to be exhaled. The exchange of gases between the alveoli and the capillaries is facilitated by the thin walls and the large surface area of the alveoli.
The oxygenated blood in the capillaries gives the lungs a pinkish color. This is because oxygenated blood is bright red in color due to the presence of oxygen-bound hemoglobin, a protein in red blood cells that carries oxygen. As the oxygen-rich blood flows through the capillaries surrounding the alveoli, it imparts a pinkish hue to the lungs.

B. phenotype.
C. genotype.
D. gene pool.
The answer is D) gene pool
When a pea plant with the genotype Rr is crossed with a pea plant with the genotype rr, there is a 50% probability that the offspring will have wrinkled seeds.
The genotype of the pea plant with round seeds is Rr, while the genotype of the pea plant with wrinkled seeds is rr. When these two plants are crossed, the offspring will inherit one allele from each parent. Since the genotype of the round-seeded plant has both a dominant and a recessive allele, and the genotype of the wrinkled-seeded plant has only recessive alleles, there is a 50% probability that the offspring will have wrinkled seeds.
