Answer:
Hypertonic
Explanation:
The cells of the critter are shriveling indicating that there is a high solute concentration in its cells. Hypertonicity causes the cells to shrink because water is leaving the cells to the external solution which one can deduce is also hypertonic.
<u>Answer:</u>
Compound light microsocope.
<u>Explanation:</u>
The compound light microscope utilises sets of lens to get bigger view of the object in steps. It is made up of more that two lens and has its own source of light.
So as to find out the amplification while reviewing a picture with a compound light magnifying lens, take the intensity of the target focal point which is at 4x, 10x or 40x and increase it by the intensity of the eyepiece which is regularly 10x.
In this way, a 10x eyepiece utilized with a 40X target focal point, will create an amplification of 400X. The unaided eye would now be able to see the example at an amplification multiple times more noteworthy thus minuscule subtleties are uncovered.
