BIOD 171 Portage Learning Exam 3 Questions With Verified Answers Define the measurements micrometer and nanometer. - answerA micrometer is one-millionth of a meter and a nanometer is one-billionth of a meter. What are the two critical factors that influence your ability to see an object? - answerThe resolution and the contrast. Resolution is the distance between two objects where you can still see them as separate. Contrast is the difference in light between two objects. If you wish to in...

Cytology - the study of cells Robert Hooke - - observed cork could float - discovered a honeycomb-like structure in a cork slice using a primitive compound microscope - only saw cell walls as this was dead tissue - coined the term "cell" for these individual compartments he saw Two types of microscopes: - 1. Light Microscope 2. Electron Microscope Light Microscope - - light is focused on specimen by a glass condenser lens - the image is magnified by an objective lens and an ocular lens...

FINAL EXAM 1. True or False: A virus is considered a microorganism. False. Viruses are not living and as such are not considered microorganisms. Viruses can, however, be classified as microbes, a more general term that includes microorganisms and viruses. 2. What is the smallest biological unit of life? A cell. 3. At a generalized level, all cells are comprised of what? Macromolecules* *A student may also answer: Proteins, Lipids, Nucleic acids and Polysaccharides but they must answer ...

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...
