1. Why is it helpful that the transmission compound light microscopes we studied in lab are both parfocal and parcentered? Why would it be harder to find a specimen on a slide starting with the 40x objective lens compared to the 4x objective lens? Support your answer with facts about the field of view and the comparison of both objective lenses. If I wanted to observe something, let's a virus that was 50 nm in size which microscope would you recommend me using? Support your answer with facts about the microscope's utility.

Microbial Growth

The development of microbial growth is influenced by various natural conditions (both physical and synthetic) like pH, temperature, saltiness, gas focus (O2, CO2, and H2), nutrients, water action, and assimilation. Knowing the distinctive physical and chemical factors that influence the development and endurance of microbial growth in the climate will assist with reinforcing endeavors outfitted towards their control. These lines lessen or diminish their harmful impacts on humankind, creatures, and the climate.
