A) Net movement in osmosis is from areas of higher water concentration to areas of lower water concentration. Net movement in diffusion occurs from areas of higher solute concentration to areas of lower solute concentration.
This happens so that both solution have roughly the same concentration
Answer: Antibodies are proteins that are found in the body on the surface of red blood cells and in the blood plasma ,they are very sensitive to foreign bodies and bad viruses and bacteria,when they notice the presence of anything that poses harm or a threat to the body system,they track it down and fight/destroy it.
Antibodies also play crucial role in hemostasis(stoppage of bleeding) in the sense that when the body is wounded or when someone gets a cut antibodies that are found in the plasma and some substances found in the platelets are released to play a role in sending signal to the blood clotting factors in the blood to be released to arrest the bleeding and prevent the person from bleeding out their entire blood.
When we go to the beach one of the most exiting activities that we do is of course collect the best looking seashells. Now I have never seen seashells in another place other than the beach.
My point in this entery that I have just mentioned is that where there is seeashells there is body of water. What those fossils mean is that that particular place whhere those seashells were once found means that maybe a very long whille back that place was onetime a body of water. Some natural dissaster came and that place doughtet and the water moved to some place else.
My pleasure to help, over and out ;)
