Answer:
True
Explanation:
Diffusion is a passive process (no energy required) in which the substance such as liquid and gases moves from an area of high concentration to an area of low concentration.
During respiration, carbon dioxide diffuses from the blood into the alveoli and oxygen diffuses from alveoli to blood across the respiratory membrane. The partial pressure of oxygen is low in the blood of the pulmonary capillaries and high in the alveoli. so diffusion allow movement of oxygen across the respiratory membrane from the alveoli into the blood.
Hence, the given statement is true.

To me we wouldn't know as much as we do. There is so much they don't want us to know about space. Just watch the moon at night and you can get a better answer.
Answer:
D. decrease the amount of erosion along the hillside
Explanation:
When logging operations are conducted on a hillside near a river, the operations will decrease the amount of erosion along the hillside because the tree's root hold soil particles and does not allow them to erosion. We can see in many region that there is presence of vegetation on the bank of river or stream in order to prevent erosion of soil so that's why we can say that logging operations causes decrease erosion along hillside.
Urine forms as some of the blood plasma spills out, some of these spilled plasma components are taken back up into the blood, and other material is selectively sent out to be added to the urine. In other words, there are three main things happening to form urine.
glomerular filtration (blood plasma spills out) bullet tubular reabsorption (some items are selectively reabsorbed into the blood) bullet tubular secretion (some blood plasma items are selectively sent out into the tubules)
