100x with oil immersion
A 100x oil immersion objective is best for studying bacteria under a microscope as it provides the highest magnification and resolution needed to observe bacterial morphology and structure in detail. Additionally, the use of oil immersion helps to reduce the refraction of light and improve image clarity.
Yes, Alexander Fleming did study bacteria. He is best known for his discovery of the antibiotic properties of penicillin, which revolutionized the field of medicine and earned him a Nobel Prize in Physiology or Medicine in 1945. Fleming's work on bacteria helped pave the way for the development of modern antibiotics.

Bacteria collects nutrients from dead organisms.
Others will not but bacteria will if you don't be careful blood will spill.
Spell study right
Bacteria typically grow best at a pH level around 6.5 to 7.5.
100x objective on the microscope is the most commonly used in microbiology because if you got a higher objective you would just have higher magnification. But you would not be able so see the details.
Just frequently enter your best trained horses in to the competitions that they are best at.
That is a matter of opinion, not objective fact.
by a variety of subjective and objective criteria
