Answer:
Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through. Extensive blood supply - ensuring oxygen rich blood is taken away from the lungs and carbon dioxide rich blood is taken to the lungs.

Answer:
<h2>
The probability of a cross between RRYY x RrYy to generate a yellow and wrinkled seed offspring is 0%.</h2>
Explanation:
Circular and yellow seeds are overwhelming and wrinkled and green seeds are passive. It is vital to keep in mind that resective characteristics are as it were displayed when the sibling has two passive alleles for those characteristic, in the event that the descendant includes a latent allele and a overwhelming allele, the characteristic that will be presented is the overwhelming one. For this reason, able to say that a cross between RRYY x RrYy plants, would not create any descendant with wrinkled and yellow seeds. Typically since, the descendant of a crossing, must show an allele of each parent. One parent as it were has overwhelming alleles (RRYY), so able to say that all descendant will get 1 overwhelming allele for color and a overwhelming allele for seed surface, anticipating the sibling from communicating latent characteristics.
