In order to understand the question let's retrace the path of blood in the right side of the heart. From the superior and inferior vena cava, the blood is recieved body, and is deoxygenated. From there the atrium pushed blood into the right ventricle. The right ventricle and left ventricle contract during systole pushing blood into two vessels. The vessel your concerned about, needs to be oxygenated, so it is presumed the blood is pumped into the pulmonary artery.
Your answer is the "pulmonary artery".
D is false. Decomposers are a separate level in of itself, so as far as “decomposers play a role at all trophic levels” go, the answer choice would be invalid, and thus forth is the correct answer. All other answers seem to be valid.
Depednign on what the cell is trying to transport there could be a variety of ways for the cell to transfer materials.
If the item is small and np then it can go through the lipid bilayer.
Simple diffusion and facilitated diffusion are passive transport meaning the cell does not need energy to transfer the membrane
and active diffision means they need to spend energy.
you need transmembrane protiens to move things inside the cell
