Answer:
C. Osmosis
Explanation:
Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane. Osmosis is a very useful for moving materials in and out of the cell.
Solutions are mixtures of solutes and solvents. The main aim of osmosis is for all the mixture part to be uniform and the solvent equally dispersed to all the part of the solution.
Osmosis is controlled to a large extent by concentration gradient.
Diffusion on the otherhand is the movement of molecules of a substance from one position to another.
Facilitated diffusion and active transport are just mechanisms for transport within a cell or a body.
Hemoglobin means blood so its most likely Sickle Cell disease
Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
Answer:
The first flower can self pollinate because it is open, so the wind will pollinate it.
Explanation: Flower b will not self pollinate because it is not open, so it will not pollinate until a bird or moose or any other animal comes and eats it, then poops it out, so the seeds get planted.
It would be 'Cold water sinks, warm water rises, creating a convection current.'
