The answer is thinner. the air gets thinner :)
Answer:
C. Water will move into the cell through osmosis. The salt and water concentrations will become similar inside and outside the cell.
Explanation:
Osmosis is the movement of water from its higher concentration to the lower concentration through a semi permeable membrane. Here, the cell have higher salt concentration and lower water concentration as compared to its outside. Since cell membrane is semi permeable, salt cannot pass through it. So, water will move into the cell through osmosis to equalize the salt and water concentration on either side of cell membrane.
<span>Anton van Leeuwenhoek learned to grind lenses ( 1668) and develop simple microscopes.
</span>
Leeuwenhoek heated the middle of a small soda glass rod , over a flame. On pulling apart the two ends, the glass rod elongated into thin whiskers .
Heating the end of this whisker resulted in a tiny high quality glass sphere. These glass spheres then became the lens of his microscope, with the smallest sphere providing the greatest magnification.
Leeuwenhoek's designs were very basic. The body of the microscope was a single lens mounted in a tiny hole on a brass plate. The specimen was then mounted on a sharp point that sticks up in front of the lens. It's position and focus could be adjusted by turning the two screws.
The entire instrument was about 3 to 4 inches long and had to be held up close to the eye, requiring good lighting and great patience to use.
