This property of water causes water to stick to other substances.
What is adhesion?
100
Substances with a pH of 4 are this.
What is acid?

This term means that there is HIGHER solute (i.e. salt) OUTSIDE the cell than inside the cell. The result is that the solution will "suck" water out of the cell, causing the cell to shrivel.
What is hypertonic?

A substance with a pH of 7 is this.
What is neutral?
200
This is the generic term for anything that is dissolved in something else. (i.e. salt or sugar, which is dissolved in water)
What is solute?

These parts of the experiment remain the same in ALL groups.
In other words, these are things that the experimental group AND the control group receive.
What are constants?

A microorganism which releases water into its environment to regulate its salinity during osmosis is undergoing a process that is similar to a human being who releases moisture on a hot day. This process that helps keep both the microorganism and the human body fluids in balance is known as —
(NOTE: when this is an answer choice on the SOL, it is ALWAYS the right answer)

Roderick had a new pair of Air Jordans and always seems to mess up his shoes within a few weeks months. He heard of a new product called AirWearRepair, which was supposed to keep your shoes looking brand new for up to 4 months. Given his bad luck with his new kicks, Roderick decided to apply the AirWearRepair to only the right shoe of his new Jordans. He wore the new pair of shoes for one month. At the end of the one month, he compared the two shoes to see if the right shoe with AirWearRepair looked any better than the left shoe without AirWearRepair. In this experiment, what is the dependent variable?
What is the condition of the shoes?

During science class, a group of 7th-grade Life Science students listed (below) some properties of water. Looking at this list, which property is NOT accurate?
a. Water is MORE dense (sinks) when it is frozen solid (is ice).
2. Water takes A LOT of energy (and time) to heat up
3. Water is able to dissolve MANY substances
4. Water helps us COOL down when we are HOT

BONUS 500 POINTS: On your board, explain WHY the answer choice you picked is NOT a quality of water.
