Which microscope did Anton van Leeuwenhoek use to observe single-celled organisms?
likoan [24]
<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.

Question 5
pantera1 [17]

Answer:

The solubility of a gas in a liquid occurs faster if the liquid is cooled. Hence the correct answer is option B.

Explanation:

The solubility of a gas in a liquid occurs faster than a solid. Solid solute takes much time to be dissolved in a solvent. This is because of the bonding. The bond of the solid is is much stronger when compared to the gaseous state. This is one of the reasons of gaseous dissolving faster than solid.

A gaseous state is defined as a material whose atoms are not closely attached with one another and is free to move in any direction. And when we have to mix gas in a liquid in a faster rate the liquid temperature should be lowered.
