The process of osmosis is the movement of water through a selectively permeable membrane from an area of higher concentration to an area of lower concentration.
If a living cell is placed in 1% sugar solution outside the cell would be hyper-tonic relative to the inside of cell. There would be a gradient between the inside cell and outside environment. Osmosis is the movement from higher to lower concentration, therefore the cell will lose water and it would dehydrate.
D can be eliminated because the temperatures where changed in 3 ways, not two.
A is true, but doesn't apply to the actual experiment "design"
B we don't know for sure, it just looks like a cup/glass.
Best answer for you: C
C is true- it was tested with a single independent variable (one that does not change) on multiple trials (the different temperatures)
Food cooking is an example of an endothermic reaction, because removing the source of heat would cause the reactions to stop
Answer: Option D
<u>Explanation:</u>
Cooking food is an example of endothermic or the heat-absorbing reaction where heat is absorbed by the system from the surrounding. Food is cooked by absorbing heat from the surroundings. Hence the temperature of the surrounding decreases.
Now when the source of heat is removed that would cause the reactions to stop. In an endothermic reaction an external heat is required for the reaction to proceed. Hence when the heat is removed and as the product is not that stable it is liable to stop the reaction.
I think the answer is b or f
