Answer:
A cell is placed in a highly concentrated salt solution. What will most likely happen to the cell if left in the solution? The cell will shrink in size, losing water due to osmosis.
There is no such thing as pure water, when you buy bottled water you think you're buying pure water but it's the same water.
I'm not going into the scientific facts here but the truth is 'pure' water does not exist because that means the water will have NOTHING in it which means they will have to remove the natural minerals and then the water will interact with any organic materials the water encounters, including air and plastic.
<em>But the water is clean and healthy to drink. Just not pure.</em>
The first colorimeter is precise, but it is not accurate. It seems to have a zero error of -5.
We can conclude its precision because the readings are closely grouped, but its lack of accuracy is due to its variation from the actual value. Moreover, the variation is consistently of 5 points lower than the actual value, so its zero error may be -5.
The second colorimeter may be referred to as being accurate.
