<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.
Answer:
Biogenesis
Explanation:
Biogenesis has permitted rapid advances in our understanding of structural macromolecules from living cells. Biogenesis theory was first coined by Rudolph Virchow and countered the claim of organisms being in existence according to the Big Bang Theory technique. Biogenesis involves the study of how organisms evolved from smaller ones to become complex.
Biokinetics deals with ways to maintain a healthy body through physical activities. Bio thermodynamics deals with the flow of energy in a biological system while Bioinformatics deals with the use of computer and technology in data analysis.
That is phsycogenic i know from personal experience
DNA ligases close nicks in the phosphodiester backbone of DNA. Biologically, DNA ligases are essential for the joining of Okazaki fragments during replication, and for completing short-patch DNAsynthesis occurring in DNA repair process. There are two classes of DNA ligases.
