Biology

aniked [119]4 years ago
8 0

Answer:

the alveoli are made of thin squamous (type I) alveolar cells which allows for the quick diffusion carbon dioxide and oxygen.

Explanation:

Diffusion of gases takes place between the alveolar cavity and the blood in the capillaries. Oxygen being more concentrated in the alveoli diffuses across the epithelium of the alveoli and the endothelium of the capillaries into the blood. The epithelial walls of the alveoli are moist and thin thus enhancing the diffusion.

Determine the results from a cross of a mother who is heterozygous for tongue rolling with a father who is homozygous recessive
grandymaker [24]
In order to determine the results from a father who is homozygous recessive for the tongue rolling trait, T, and a mother who is heterozygous for the trait, a Punett square can be used to determine both the resulting genotype (allele combination) and phenotype (observable characteristics). The results are 50% Tt and 50% tt. Thus, the cross would result to 1:1 ratio of tongue rolling to non-tongue rolling offsprings.

What is the difference between the ligamentum arteriosum and the ductus arteriosus?
Goshia [24]
In fetal life, the lungs are not expanded, so most of the blood from the right ventricle is shunted from the pulmonary artery to the aorta through the patent ductus arteriosus. With a few breaths the lungs expand, and blood flows from right ventricle to pulmonary artery into the lungs. Withdrawal of circulating prostaglandin from the mother plus bradykinins released from the expanding lung of the infant cause the ductus to close over a few minutes to hours. The closed ductus remains as the ligamentum arteriosum.
