Chapter 2, Problem 2A
Microorganisms use hydrogen bonds to attach to surfaces. Many of the cells lose hold of the surface because of the weak nature of these bonds. Contrast the benefits and disadvantages of using covalent bonds as a means of attaching to surfaces.

- A microbiologist has isolated a new strain of bacteria, and is trying to characterize aspects of its growth. Three flasks of the same media have different amounts of NaCl added. Other growth conditions are identical, and the flasks inoculated at the same time. At regular intervals over a 3 hour period, culture samples are taken and turbidity is measured. Here are the absorbance values over time in a table and graphed.

Which description best fits what will happen. 1) The environment is hypertonic to the contents, so the bag will shrink as water leaves the bag. 2)The environment is hypotonic to the contents, so the bag will expand as water enters the bag. 3) The environment is hypertonic to the contents, so the bag will expand as water enters the bag. 4) The environment is hypotonic to the contents, so the bag will shrink as water leaves the bag.arrow_forwardThe principles of osmosis are used in food preservation. Certain foods are stored in strong salt solutions (brine) or in syrups to prevent infection by microbes. a) Explain how the principles of osmosis apply to this situation. b) What effect will these solutions have on the micro-organisms?arrow_forward
- Bacterial growth depends on many environmental factors, including the temperature of the environment. Since microbes can survive in a certain range of temperatures and will thrive at a temperature, understanding these variables allows for control of their growth. This understanding can be used, for example, to preserve certain foods or to treat infections. This lab simulation will use an instrument called a spectrophotometer. This instrument quantitatively measures the amount of light that is absorbed or transmitted by molecules in solution. Microbial populations grow at different rates based on temperature. One way to measure growth is by turbidity measurements. When bacteria multiply in a broth culture they turn the clear solution cloudy, or turbid. a) in your own words explain the proper steps to Inoculate 5°C sterile broth tube using aseptic techniquearrow_forwardWhich of the following treatments would be most useful in removing integral membrane proteins from a membrane sample? change the pH add a detergent add salts add proteasesarrow_forwardIf a scientist drops an animal cell into a solution that contains 10 times more salt than is found inside the cell, which of the following will happen? Hint: drawing a picture may help you. A) The cell will burst since the solution is hypertonic B) The cell will shrink since the solution is hypotonic. C) The cell will burst since the solution is hypotonic. D) The cell will shrink since the solution is hypertonic. E) The cell will not change in size since the solution is isotonic.arrow_forward
