Answer:
The correct option is<u> slight increase in salt concentration in the
</u>
<u>environment.</u>
Explanation:
The main function of contractile vacuole in the body of a paramecium is to pump out excess water. But an increase in salt concentration in the environment will let the water move inside the cell by osmosis. Hence, the contractile vacuole will not perform its function and will not be able to regulate osmoregulation.
Other options are incorrect because slight changes in the temperature or pH won't affect the contractile vacuole and it will still be able to perform its function.
Answer:
B
Explanation:
Facilitated diffusion because the transport channel proteins facilitate(help) the particle to enter the cell

Answer:
presence of sugar means that the outside of the fruits is less dilute (more concentrated in sugar than water) than the inside of the fruits
in osmosis (diffusion of water molecules), water molecules have a net movement from a more dilute substance to a less dilute substance
sugar is the less dilute substance, so water is drawn out of the fruits and mixes with the sugar around them
the sugar dissolves in water, creating a sugar solution
this results in fruits with less water inside them, and surrounded by sugar solution
Hope this helps :)))
