Portage Learning BIOD 171 Microbiology Lecture Exam Key 1-6 Exams 1. What are the two major types of nucleic acids and their roles? DNA- deoxyribonucleic acid RNA- Ribonucleic acid DNA- Cellular life has DNA and a role that DNA has is long-term storage of information, it holds the characteristics of living organisms. RNA- Is the carrier of information in form of amino acid sequence. It converts the information in the DNA and synthesizes proteins Tru...

BIOD 171 Portage Learning Exam 3 Define the measurements micrometer and nanometer. - ANSWER-A 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? - ANSWER-The 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 increase the amount of light goin..

A nanometer is defined as: - 10-9 A nanometer is defined as one-billionth of a meter True or False: A nanometeris longer than a micrometer - False. A nanometer is 1,000 times smaller than a micrometer. Resolution and contrast are two critical factors that influence your ability to see an object. Explain each. - Resolution refers to the distance between two objects at which the objects still can be seen as separate. Poor or low resolution means two (or more) objects may appear as one. *Cont...

Biology 1406 Lab Exam 1 Questions and Answers Already Passed Why is oil immersion used? To reduce the amount of light rays that are refracted away from the objective lens. It increases numerical aperture and maintains a uniform light speed. increase the resolving power of a microscope. Prevents refraction of light. What parts of the microscope does light travel through? Illuminator-The light source for the microscope.Diaphragm-Controls the amount of light entering the condenser. Co...

A nanometer is defined as: - 10 -9 or one-billionth of a meter True or False: A nanometer is longer than a micrometer - False A nanometer is 1000x smaller than a micrometer Resolution and contrast are two critical factors that influence your ability to see an object. Explain each. - Resolution refers to the distance between two objects at which the objects can still be seen as separate. Poor or low resolution means two or more objects may appear as one. Contrast on the other hand is the d...

micrometer one millionth of a meter, 10^ -6 2. nanometer one billionth of a meter, 10^-9 3. Resolution the distance between two objects at which the objects still can be seen as separate 4. What happens if the resolution is poor? Poor or low resolution means two (or more) objects may appear as one. 5. Contrast the difference in light absorbance between two objects. 6. What happens if there is poor contrast? gives a high background and makes the visualization of multiple objects diff...
