I guess that is:
Within the capillaries of the lungs, gases are exchanged by diffusion; O2 diffuses from the alveolus to the bloodstream and CO2 diffuses from the bloodstream to the alveolus.
The best and most correct answer among the choices provided by your question is the second choice or letter B.
Reptiles don't sit on their eggs like birds do because r<span>eptile eggs are not amniotic and have no shell, so sitting on them would crush them.</span>

Upon crossing BB with bb, we will get a hybrid of Bb.
- Codominance is a phenomena in genetics where two alleles (different forms of the same gene) express themselves equally in an organism. As a result, characteristics linked to each allele are shown at the same time.
- The MN blood group system in humans is an illustration of codominance. M and N alleles control the MN blood type. Red blood cells from people who are homozygous for the M allele carry a surface molecule known as the M antigen. On their red blood cells, those who are homozygous for the N allele contain the N antigen. A heterozygote is a person who carries both antigens.
- (a) Genotype of blue scales fish will be BB.
- (b) Genotype of blue scales fish will be bb.
- (c) Genotype of blue scales fish will be Bb.
So, in this case B and b alleles will express equally.

Answer:
The grasshopper doesn't have to use it circulatory system to carry gases to and from the grasshopper cells because the air that is passed through the trachea system is already close enough to get to the cells.
Explanation:
"In the grasshopper, exchange of oxygen and carbon dioxide occurs in the tracheal system. Hemolymph plays no part in the process. There is not even an oxygen-carrying pigment in insect hemolymph." - www.biology-pages.info
