First, we will elaborate the terms that are being used.
Heterozygous:
This means that the organism has a set of alleles which are different from one another. One copy may be for the dominant trait and the other for the recessive one.
Homozygous:
The organism has two copies of the same allele
Dominant:
An allele that will express itself even if only one copy of it is present. These are usually represented by capital letters.
Recessive:
An allele that requires both copies to be expressed. These are usually represented by lower-case letters.
A: Heterozygous
B: homozygous recessive
C: Homozygous dominant
D: Homozygous recessive
E: Homozygous dominant

Answer:
The concentration gradient of oxygen in your lungs wants to flow toward homeostasis and oxygen is bound on red blood cells by hemoglobin, along with the attraction of oxygen to hemoglobin. The concentration gradient from carbon dioxide from the capillary to the lungs. There is more oxygen in your lungs (alveoli) than there is carbon dioxide and everything want to reach homeostasis, or level amounts on both sides.
Explanation:
Correct answer - Tetrahedral, planar or flat.
Why? - When carbon forms single bonds with other atoms, the shape is tetrahedral. When two carbon atoms form a double bond, the shape is planar, or flat. Single bonds, like those found in ethane, are able to rotate.
