Magnification - Answer -ability to enlarge objects Resolving power - Answer -smallest seperation at which two seperate objects can be distinguished Total Magnification - Answer -of the final image is a product of the seperate magnifying powers of the two lenses -Objective power x Ocular power = total magnification Resolution - Answer -the capacity to distinguish or seperate two adjacent objects and depends on the wavelength of light that forms the image along with characteristi...

BIO 235 Microbiology Exam TEST 1() units of measurement - CORRECT ANSWER1 µm = 10-6 m = 10-3 mm 1 nm = 10-9 m = 10-6 mm 1000 nm = 1 µm 0.001 µm = 1 nm total magnification (compound microscopes) - CORRECT ANSWER-the image from the objective lens is magnified again by the ocular lens -total magnification = objective lens x ocular lens resolution - CORRECT ANSWER-the ability of the lenses to distinguish two points. -shorter wavelengths of light provide greater resolution objective l...

2022 AQA GCSE Biology Paper 1. What are the two types of cells? - Answer - ● Eukaryotic (plant and animal) ● Prokaryotic (bacteria) What are the differences between eukaryotic and prokaryotic cells? - Answer - Prokaryotic cells are much smaller than eukaryotic cells. Eukaryotic cells contain membrane bound-organelles and a nucleus containing genetic material, while prokaryotes do not. How is genetic information stored in a prokaryotic cell? - Answer - Found free within the cytoplasm a...
