The peptidoglycan can of bacteria has been campared with the chain mail worn beneath a medieval knights suit of armor. it provides both protection and flexibility. can you describe other structures in biology that have an analogous function? how are they replaced or modified to accommodate the growth of the inhabitant?
Gram staining is a common technique used to differentiate two large groups of bacteria based on their different cell wall constituents. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls, which retains the crystal violet these cells are stained with. Alternatively, Gram negative bacteria stain red, which is attributed to a thinner peptidoglycan wall, which does not retain the crystal violet during the decoloring process
- s. epidermidis a gram-positve coccus
- E. coli a gram-negative bacillus
- C. xerosis a gram-positive bacillus
How does each organism fulfill a specific niche based on the information provided above?

- A bacterium has the following characteristics: I. It adheres to the human intestinal lining using a feature that protects it from phagocytes , bacteriophages, and dehydration. II. It can survive being boiled. III. It contains no plasmids and relatively little peptidoglycan. Which of the following characteristics allows this bacteria to survive in a human who is taking penicillin pills? A. gram-negative cell wall B. peptidoglycan in the cell wall C. lipopolysaccharides in the cytoplasm D. long polypeptides in the cell wallarrow_forwardBacterial 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 a) In your own words give an introduction to the microbial growth and the effect tempature has. b) In your own words explain the importance of the spectrophotometer in regards to microbial growth. c) In your own words give a hypothesis on how bacteria will react to different temperatures.arrow_forwardIn 1928, British bacteriologist Alexander Fleming made an accidental discovery. He noticed that a fungus had contaminated one of the agar plates he had streaked with a bacterial species to be studied. The fungus prevented the bacteria from growing in the immediate area surrounding the fungus. Upon further investigation, Fleming found that the fungus produced a substance that was the agent responsible for killing the bacteria. He called this substance penicillin. Given this information, which statement best explains why Fleming's discovery is relevant to the general public today? O Fleming's attention to detail diverted his efforts to investigate bacteria and likely robbed humanity of important discoveries that he would have otherwise made. Fleming's sloppiness in the lab serves as a reminder to all researchers that sterile technique is critical to preventing unwanted fungal growth on bacterial plates. Fleming's discovery enabled the development of chemical substances as antibiotics to…arrow_forward

In one case it is a plasmid that is transferred via conjugation, in the other case it is a part of the bacterial chromosome that is transferred via transformation. In which of the two cases is it most likely that the transferred DNA will remain and be able to function in the recipient cells? Explain the biological background to your answer .

Some park attendants said that their dogs took a dive in one of the park’s ponds and after few days they became sick. So, you went to the park and took a sample of the water to analyze it.11) To which one of the kingdoms you are expecting to find representative of that caused the dogs to become sick?12) Name the Phylum13) To which class (or group) of organisms they belong to?arrow_forwardGram-negative bacteria are surrounded by two membrane bilayers separated by a space termed the periplasm. The periplasm is a multipurpose compartment separate from the cytoplasm. The periplasm has a distinct oxidizing environment that allow certain key protein structural features to be formed. Can you identify an amino acid(s) that would be affected by this oxidizing environment? How would it be affected, and what structural features would be sensitive to this environment? Can you discuss the implications of this from a standpoint of recombinant protein expression?arrow_forward
- A scientist isolates a new species of prokaryote. He notes that the specimen is a bacillus with a lipid bilayer and cell wall that stains positive for peptidoglycan. Its circular chromosome replicates from a single origin of replication. Is the specimen most likely an Archaea, a Gram-positive bacterium, or a Gram-negative bacterium? How do you know?arrow_forwardMicrobiologists have announced the discovery of over 30 new species of bacteria that thrive between the teeth and gums of humans. The bacteria could not be grown in the researcher's laboratories, nor were any of them ever observed via and kind of microscopy. If they couldn't culture them or see them, how could the researchers know they discovered a new species? If they couldn't examine the cells for the presence of a nucleus, how did they determine that the organisms were prokaryotes and not eukaryotes?arrow_forwardYou treat a cell with a fluorescently-labelled antibody that recognizes microtubules, and you observe what appears to be a spindle apparatus. Is the cell a prokaryote or a eukaryote? Explain. Some archaebacteria species live in extremely high-salt environments. Cite a specific example of protein modification that has allowed these bacteria to accomplish this.arrow_forward
