Thr answer is c sorry if am wrong
Answer:
Diffusion occurs when there is movement of minerals from an area of higher to lower concentration, till equilibrium is obtained.
Whereas Osmosis is the movement of solvents rather then the solute, from a solution of lower to a solution of higher concentration with the help of semipermeable membrane.
Explanation:
Diffusion is the movement of substances from area of higher concentration to an area of lower concentration of minerals, which mainly results in animal cells. Whether solute or solvent, diffusion occurs for both. Diffusion does not requires any semi permeable membrane. Diffusion occur in all state of matter, that solid, liquid and gas, whereas osmosis occurs only in liquid state. Osmosis requires semipermeable membrane and rate of which is related to concentration of solute dissolution in solvent medium. Only movement of solvent medium takes place. Classical example of osmosis is exhibited by cell membranes of animal cells. On the other hand diffusion is the spreading of perfume or fragrances to the external air.
Answer:
Hypothesis. A Hypothesis is an estimation of what might happen and the student's observation before moving on to investigate.
<span>Three fossil fuels are, natural gas, coal and oil
I guess what could differentiate them is that: </span>Coal is a solid fossil fuel formed over millions of years by decay of land vegetation. When layers are compacted and heated over time, deposits are turned into coal. Whereas Oil is a liquid fossil fuel that is formed from the remains of marine microorganisms deposited on the sea floor and gas like oil, it is formed from the remains of marine microorganisms.<span>
So the difference could be how they are formed</span>
C 1650 Because you have to factor in the difference of BC and AD. you must get 1200 BC to 0 first, and then go to 450, therefore getting 1650
