Answer:
Hemoglobin.pulmonary artery.
Explanation:
1. about hemoglobin.Hemoglobin is the protein inside red blood cells. It carries oxygen.
2. about pulmonary artery.The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.
3. There exist a concentration difference of carbon dioxide and oxygen inside the alveoli and capillaries due to which the diffusion of the two gases takes place. The carbon dioxide moves from the blood to the alveoli sac and the oxygen moves from the sacs to the blood.

Explanation:
Your weight is the force of gravity pulling you towards earth. A push or pull is a force. Gravity pulls everything down towards Earth. Friction slows things down like a ball rolling. If there was no friction a ball would roll forever. When you push on a door you contact it while using a force, contact force.

Answer: Exons, Introns
Explanation:
The answer is Exons, Introns
When the base sequence of related genes from different species are compared, they base sequence of exons are highly conserved because the exons represent the coding region of the DNA or RNA that code for specific amino acids and because DNA replication, transcription and translation are of high integrity genes sequence are highly conserved.
Because Introns are non coding region and may be affected by mutation easily, the sequences of nucleotides in introns are much less conserved when compared to related genes.
