If a cell is put into a solution with a higher concentration of solute than is present inside the cell, the solution is the cell will if a cell is put into a solution with a lower concentration of solute than is present inside the cell, the solution is the cell will

The answers are: Hypertonic solution, shrink;  Hypotonic solution, swell

Explanation:

A hypertonic solution is a solution with relatively higher solute concentration. Whereas, hypotonic solution is a solution have relatively lower solute concentration.

When a cell is placed in hypertonic solution, solute concentration inside the cell is less than outside the cell. Thus the water diffuses outside the cell through the cell membrane, due to osmotic pressure. This causes the cell to shrink and wrinkle.

Whereas, when a cell is placed in hypotonic solution, solute concentration inside the cell is more than outside the cell. Thus the water diffuses inside the cell through the cell membrane, due to osmotic pressure. This causes the cell to swell.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
