<span>Anton van Leeuwenhoek learned to grind lenses ( 1668) and develop simple microscopes.

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.
If mitosis occurs correctly, the division of one cell by mitosis produces two cells.
Follicle stimulating hormone (FSH) and Luteinizing hormone (LH) are Gonadotropins stimulated in the gonads. In females, they are located in the ovaries. They are not needed for life yet important for reproduction. Progesterone which is being secreted in corpus luteum is needed for maintenance of pregnancy thus if a female has a low FSH and LH it will affect the chance of her be pregnant.
With the given results, in order for the nurse to identify
