Explanation / Answer

van Leeuwenhoek living organisms could spontaneously arise from non-living material. Endospores All of the choices are correct. using bacteria to clean up pollutants. that is due to a greater degree of interaction between humans and tick-carrying animals. a decline in vaccination of children in the previous years. All of the choices are correct. are solely due to lifestyle. they are grown quickly, easily, and cheaply. are only found on small select parts of our bodies. only in certain restricted areas. All of the choices are correct boiling hot springs AND the Great Salt Lake. prokaryotes AND archaea. Staphylococcus aureus AND S. aureus are naked (lacking a protein shell) pieces of DNA. in living cells. infectious agents. are only composed of protein. True this infection hasn't been observed in the human population prior to recent (approximately 50 years or sooner) outbreaks. genus and species. All of the above. False found that some molecules can exist as stereoisomers AND separated organic acids using a microscope electron ions All of the choices are correct. is a measure of the hydrogen ion concentration, utilizes a scale from 5 to 8 AND is a linear (not logarithmic) scale? amino acids. electric charge. All of the choices are correct. All of the choices are correct. Uracil All of the choices are correct True the number of protons equals the number of electrons. negatively charged. Hydrogen Water 20 assumes any number of equally functional shapes AND may need help, in the form of chaperones, to assume the correct shape. All of the choices are true. hydrophobic nature. defined by the presence of a membrane bound nucleus. magnify an object fluorescence microscope. All of the choices are correct. have positive charges. Gram stain basic dyes AND safranin. decolorizing too long AND using old cultures cell wall structure. smear, fix, stain may correlate with an organism's ability to cause disease, are typically "negatively" stained AND are stained as a wet mount. CTC coccus AND bacillus All of the choices are true. Water usually enters a cell and produces a tremendous osmotic pressure AND the diffusion ultimately relies on the selectively permeable nature of the cell membrane. regulate movement of molecules which enter and leave the cell. diffusion. All of the choices are true. contains a thin layer of peptidoglycan AND contains an outer membrane containing LPS. growing bacteria AND Gram-positive bacteria. may be used for protection AND may be used to help the bacteria adhere to surfaces is often referred to as run and tumble AND may involve pili. is the ingestion of particles and may be performed by animal cells is a double membrane sac containing DNA and is found in eukaryotes. They are capable of performing protein synthesis high surface area relative to low cell volume AND more rapid growth rates. True True Scanning electron microscope ocular and objective.
