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. ⦁ What is the smallest biological unit of life? A cell. ⦁ 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 with all four to be fully correct. ⦁ Which of the following microorganisms are considered to be Eukarya? Select all that apply. ⦁ Animalia ⦁ Plantae ⦁ Fungi ⦁ Protista A,B,C,D ⦁ True of False: All multicellular microorganisms classified as Animalia are Portage Learning BIOD 171 Final EXAM Questions and Answers 100%Correct/verified Guaranteed Rated A+ 2022/2023 Portage Learning BIOD 171 Final EXAM Questions and Answers 100%Correct/verified Guaranteed Rated A+ 2022/2023 heterotrophic. True ⦁ Microorganisms classified as Plantae obtain most of their energy by converting energy into energy. Light (sunlight); chemical (sugars) ⦁ Define catabolism. Catabolism is the process of breaking down larger molecules into useful energy sources. ⦁ Upon cellular injury, which metabolic process is involved during the growth and repair phases of the cell? The anabolic process would be active as it (by definition) is involved in the building up of small complexes into larger complexes. ⦁ In phosphorylation, the light reactions always occur where? The process of converting light energy into chemical energy (photophosphorylation) always occurs in the membrane. ⦁ True or False: The Calvin cycle must occur in the absence of light. False. The term ‘dark reactions’ (also known as the Calvin Cycle) simply denotes the second stage in photosynthesis—dark reactions do not actually require Portage Learning BIOD 171 Final EXAM Questions and Answers 100%Correct/verified Guaranteed Rated A+ 2022/2023 Portage Learning BIOD 171 Final EXAM Questions and Answers 100%Correct/verified Guaranteed Rated A+ 2022/2023 darkness in order to occur. Assuming a constant (non-adjustable) light source power, identify the part of the microscope you would adjust to limit the amount of light entering the microscope. Select all that apply. ⦁ Objective ⦁ Condenser ⦁ Iris diaphragm ⦁ Eye piece C. The iris controls the amount of light that passes through the sample and into the objective lens. Thus, it can be adjusted (opened or closed) to alter the amount of light. ⦁ What is the total magnification (relative to your eye) of a sample imaged with a 60x objective and a 10x eyepiece? Show your math. 60 x 10 = 600x magnification Portage Learning BIOD 171 Final EXAM Questions and Answers 100%Correct/verified Guaranteed Rated A+ 2022/2023 1. Identify what type of electron microscope was used to capture the following image and explain your choice. The image was captured using a Scanning Electron Microscope (SEM). The above image shows the trademark ‘shell’ image (no subcellular organelles are visible) reminiscent of SEM. Only TEM is capable of visualizing subcellular substrucutres. ⦁ True or False: LB agar is classified as a selective, non-differential media. False. LB agar is the most basic type of agar and like LB media supports the growth of virtually all microbes without restriction. ⦁ What is agar used for in microbiology? Agar is used to create a solid, smooth surface on which microbes can grow. ⦁ True or False. When performing a dilution streak a new (or sterilized) loop is not required for each phase as long as the bacterial culture is pure. Portage Learning BIOD 171 Final EXAM Questions and Answers 100%Correct/verified Guaranteed Rated A+ 2022/2023 False. The number of phases (3 vs. 4) and/or the number of times a loop passes through a previous phase (once vs. multiple times) is acceptable provided what happens? Either deviation is acceptable in practice provided the resulting gradient contains within it the growth of individual colonies—if not, the experiment must be repeated. ⦁ True or False. Pathogenic strains of bacteria tend to grow slower than normal non-pathogenic bacterial strains. False. 1. Match the following symptoms with their respective diseases: ⦁ Folliculitis D ⦁ Scalded- skin syndrome E ⦁ Impetigo A ⦁ Conjuncti vitis ⦁ Childhood skin disease near mouth/ nose ⦁ Infection of thin, transparent scleral tissue ⦁ Infection occurs at time of birth ⦁ Pus-filled lesions on skin or hair B Portage Learning BIOD 171 Final EXAM Questions and Answers 100%Correct/verified Guaranteed Rated A+ 2022/2023 Ophthal mia Neonatoru m C  ⦁ Ruptured pustules; treated with Penicillin 2. True or False. The causative agent of conjunctivitis can be either bacterial or viral. True. ⦁ True or False. There are currently no cures for tetanus. True. ⦁ Identify the medical condition
