1. What is a model organism and why is it important to scientific studies? List two common model organisms, one for prokaryotic studies and one for eukaryotic studies.

What is life? Why are viruses not considered alive? What other things can you think of that are not alive but might be almost alive?

Describe at least 3 things scientists can look at to separate eukarya from bacteria and 3 things scientists can look at to separate bacteria from archaea.

Imperial China during the Ming dynasty (1368-1644 CE) could conceivably have started the Scientific Revolution before Europe; its failure to do so might have resulted (at least in part) from each of the following factors except: foreign trade was dominated by the Imperial Navy, with no profit motive for merchants European sailing vessels of that time were much smaller than Chinese treasure ships Chinese religion was polytheistic, while the central government at that time was strong military expenditures were diverted from ship-building to land-based armed forces Chinese colleges were independently-chartered, not under Imperial control like Europe

Eukaryotes are sometimes termed nature’s master builders. Why is this a more apt description for members of the Eukaryotic branch tree of life than Prokaryotic branches life?

1) Select the concept below that best demonstrates compartmentalization of function in living things. Group of answer choices horizontal gene transfer flatness of flatworms organelles in eukaryotic cells circular chromosome of prokaryotic cells the Miller-Urey experiment gastrovascular cavity the RNA World hypothesis

EBDOSYMBIOTIC THEORY is the evolution theory that includes a larger and one smaller cell. The larger cell act as a host and the smaller cell is called the endosymbiont that is engulfed by the host cell. The larger cell referred to eukaryotic cell and the smaller cell represent prokaryotic cell. While BIOCHEMISTRY, is the study of the chemistry of cells and organisms. Thus, it is concerned with the types of molecules found in biological systems, their structure, and their chemical properties. QUESTION: How ENDOSYMBIOSIS THEORY applies to this subject (BIOCHEMISTRY)?

1. Define and briefly describe the different classes of microorganisms (including the terms Eukaryotes and Prokaryotes): 1. Eukaryotes - a. Algae - b. Fungi - c. Protozoans - 2. Prokaryotes - a. Bacteria - b. Archae - Viruses - 3. 4. Prions - 2. Define the four main types of organic molecules. Be sure to describe their function and give examples of each a. Carbohydrates - b. Proteins - c. Lipids - d. Nucleic acids - 3. What does the term PPE stand for? What are common types of PPE that are worn in the lab or hospital setting? 4. Describe two ways in which microorganisms are used by us or by scientist/industry to improve our everyday lives. This is an applied microbiology question and answers should be directed towards this rather than normal function of microbes in the environment (including our gut microflora). 5. Identify two different types of staining techniques used with light microscopy. Describe the dyes used in these techniques and why they are used.
