umm ill find that for you or do you already know
Explanation:
Answer:
Once the oxygen diffuses across the alveoli, it enters the bloodstream and is transported to the tissues where it is unloaded, and carbon dioxide diffuses out of the blood and into the alveoli to be expelled from the body. Although gas exchange is a continuous process, the oxygen and carbon dioxide are transported by different mechanisms.
Transport of Oxygen in the Blood
Although oxygen dissolves in blood, only a small amount of oxygen is transported this way. Only 1.5 percent of oxygen in the blood is dissolved directly into the blood itself. Most oxygen—98.5 percent—is bound to a protein called hemoglobin and carried to the tissues.
Hemoglobin
Hemoglobin, or Hb, is a protein molecule found in red blood cells (erythrocytes) made of four subunits: two alpha subunits and two beta subunits (Figure 20.19). Each subunit surrounds a central heme group that contains iron and binds one oxygen molecule, allowing each hemoglobin molecule to bind four oxygen molecules. Molecules with more oxygen bound to the heme groups are brighter red. As a result, oxygenated arterial blood where the Hb is carrying four oxygen molecules is bright red, while venous blood that is deoxygenated is darker red.
D. A possible answer to a scientific question
Answer: The offspring will not be genetically identical to the mother because the process of mitosis mixes chromosomes frome the mom and dad.
Answer:
The correct answer would be - parents, offspring, and siblings of the suspect.
Explanation:
DNA percent that relatives share with an individual varies according to the type of relationship they share with the individual person. The average DNA percentage that is shared with the close biological family that is parents (mother or father), offspring (son or daughter) or the siblings (brother or sister) is about 50% which is the maximum and best choice for the DNA match for the determining whether the suspect committed crime or not.
Other relatives share only 25 % or less average DNA percentage share with the individual.
Thus, the correct answer is- parents, offspring, and siblings of the suspect
