Answer:
Oxygen molecules in the tissues of the lung diffuse into the blood because the concentration of oxygen in the lung's tissues is more than the concentration of oxygen in the blood.
Explanation:
Diffusion is the movement of molecules from the region of higher concentration of the molecule to the region of lower concentration of the same molecule. Molecules in diffusion move <em>downward the concentration</em> <em>gradient</em> created by difference in concentration between two regions until an <em>equilibrium (equal concentration in the two regions)</em> is established.
Oxygen molecules diffuse into the tissues of the lung when an organism breathes-in during the process of breathing. The molecules in the now oxygen-rich tissues eventually start diffusing into the blood in the lung because the blood passing through the lung is always de-oxygenated or has lower oxygen concentration compared to the tissues of the lung.
Oxygenated blood moves into the heart, pumps round the body by the heart, gets depleted of oxygen and eventually find its way back to the lung where the process is repeated.
Diffusion of oxygen from the tissues of the lung into the blood will keep happening as long as oxygen keeps getting dissolved into the lung's tissues and an equilibrium is yet to be established between the tissues and the blood.
Answer:
Blood is carried away from the heart by arteries. Blood that is rich in oxygen. Blood that is low in oxygen is returned to the heart by veins. there is more pressure in arteries than in veins.
the answer would be d. a start base triplet

Insect herbivory is likely to affect the competitive relationship between the species in that a plant affected by these insects will have a hard time competing with those who are unbothered by the insects.
<em>Although I could not locate the Graph or options for this question online, I can offer a general assessment to help you answer the question.</em>

Insect herbivory is when insects consume plants or parts of a plant as their main food source. Interestingly, this term also applies to those insects who do not harm the plant, but consume the pollen, etc.
However, focusing on harmful insect herbivory, we can assume that in the presence of these insects a plant will have a hard time staying alive or mating effectively due to the damage caused. Therefore, we can assume that <u>the </u><u>plant </u><u>on the </u><u>left </u><u>will not be able to stay </u><u>competitive</u>.
