Answer:
C. Water passes into the salt solution, dehydrating bacterial cells and making them harmless.
Explanation:
The salt solution is hypertonic to the bacterial cells and as such, water molecules will move from the bacterial cells into the salt solution, dehydrating the cells and rendering them harmless.
Option A is also true but it is irrelevant to the question asked. Option B and D are wrong.

Boiling and melting are both physical changes so do not involve the formation or breakage of chemical bonds.
Answer:
no
Explanation:
because hypothesis are just what we thing is gonna happen it doesn't have to be true
sorry if im wrong
25 moles of C3H8 will be produced from 75 moles of CO2.
<h3>Mole calculation</h3>
To find the value of moles of a product from the number of moles of a reactant, it is necessary to observe the stoichiometric ratio between them:
Analyzing the reaction, it is possible to see that the stoichiometric ratio is 1:3, so we can perform the following expression:
C3H8 CO2
So, 25 moles of C3H8 will be produced from 75 moles of CO2.
