in what way would the normal pattern of gas exchange between a leaf and the atmosphere be altered by coating both sides of the l

Answer:

Gaseous exchange between leaves and atmosphere would be disturbed due to blocked stomata.

Explanation:

Leaves have stomata on their surfaces. Through stomata, plants take the oxygen in for respiration. Carbon dioxide gas is also released into the atmosphere through stomata. Similarly, plants take the atmospheric CO2 through stomata to perform the process of photosynthesis. The molecular oxygen produced as a by-product during photosynthesis is also released through stomata.

Coating both sides of leaves with petroleum jelly or wax would block stomata. Leaves of the plant with coating would not be able to perform breathing and photosynthesis.

Answer:

Dominant

Explanation:

If both of the parents don't express the trait and the child does, then the pedigree is recessive.  According to Mendel's law, the recessive trait will only show if there are two recessive alleles.  If both of the parents of have the trait and their child does, that means that the parents are heterozygous.

If one of the parents have the trait and the child does or doesn't, then the pedigree is dominant.
