What would most likely be a result of skepticism ​
disa [49]

Answer:

The two most frequently made objections to skepticism target these theses. The first is that the skeptic’s commitment to our epistemic limitations is inconsistent. He cannot consistently claim to know, for example, that knowledge is not possible; neither can he consistently claim that we should suspend judgment regarding all matters insofar as this claim is itself a judgment.

Please help!<br> the question(s) are in the pdf :)
Yuliya22 [10]

Answer:

1) b) hypotonic

2) a) hypertonic

3) a) water

4) a) B to A

5) c) osmosis

Explanation:

We have two compartments with water (A) and a solution in which the solvent is water and the solute is starch (B). The solutions are separated by a semipermeable membrane, which means that only the water molecules pass through the membrane.

1) In comparison with B, compartment A has a lesser amount of solute so it is hypotonic.

2) In comparison with A, compartment B has more solute (starch) so it is hypertonic.

3) The solvent is water, which dissolves the solute (starch).

4) Only the water molecules will pass through the membrane, and the molecules always move from the compartment with a higher concentration of solute (B) to the compartment with a lesser concentration of solute (A). So, the water moves from B to A.

5) The process in which the molecules of solvent move from a more concentrated solution to a less concentrated solution through a semi-permeable membrane is called osmosis.
