Answer:
Lysosomes
Explanation:
Lysosomes are the organelles that have many digestive enzymes such as those for digestion of lipids and proteins. Most of the vesicles that bring substances into the cells by phagocytosis or endocytosis fuse with lysosomes. For example, the vesicles formed during receptor-mediated endocytosis fuse with lysosomes so that LDL particles and other substances are digested by the enzymes of lysosomes. The digested products then leave lysosomes so that cells can use them.
Answer:
Higher
Explanation:
Molecules such as oxygen move from a higher concentration to a lower concentration across a semi-permeable membrane. This process is called simple diffusion.
Therefore, for oxygen to leave the alveoli and enter the blood, there would need to be a higher concentration of oxygen inside the alveoli and a lower concentration of oxygen in the blood.
