Suppose you want to culture a species of bacteria in an environment without oxygen. You have 3 species to choose from: an acidophile, a thermophile, and an anaerobic bacterium. Which would you culture in the environment without oxygen and why?
Homework Answers
Answer:
Anaerobic process takes place in the absence of oxygen. Anaerobic bacteria can survive without oxygen presence. These can be unicellular or multicellular. There are three types of anaerobic bacteria – obligate, aerotolerant, and facultative anaerobes.
Thermophile is a type of organism that survives in high temperatures. Other bacteria can’t tolerate such high temperatures. Acidophile or acidophilic organisms live in highly acidic conditions. These two are majorly found in volcanic areas and mining places.
In general, aerobic bacteria are used in microbial culturing (done in the presence of air). If anaerobic bacteria are used in culturing, certain techniques must be followed by the microbiologists.
If one wants to culture a species of bacteria in an environment, without oxygen. Anaerobic bacterium suits the best, as it suits the condition (no oxygen content).

W GIVOTU Muu ovat LED uro. QUESTION 3 Suppose you place yeast cells in two different environmental conditions to observe their growth. Flask A contains nutrient broth that has minimal amounts of glucose and is incubated at 37°C with aeration (like a bubbler in a fishtank). Flask B has the same media, is incubated at 37°C and is kept in an anaerobic environment. The yeast are facultative anaerobes. Which culture had the greater number of cells? Flask...

Name one place on this Earth where you might find ONE species of bacterium that can be categorized to all of the 5 groups:photoautotroph, acidophile, mesophile, halophile, facultative anaerobe). Note again, this is one type of bacteria, not 5 different types. This place can be a huge piece of land/water or the outer space, but it can also be the body/tissue of a living organism. Please note that this bacterium may not actually exist. Use your imagination. Explain why this place...

2) You have identified a new clade of bacteria in marine samples and you want to identify and enumerate this specific taxon. Explain in clear methodological detail the method you would choose to do this and how this method works. 3) You think you have nitrogen fixers in an anaerobic part of your Winogradsky column. You cap the column with 15N2 gas (a non-radioactive N isotope) and want to identify the active N2 fixers in this region of the column...

- Describe a circumstance (e.g. in its’ natural environment) where Staphylococcus species bacteria might benefit from being salt tolerant. - How might the ability to perform hemolysis benefit a hemolytic organism in its’ natural environment? - Imagine that you have a culture containing a single bacterial species. This culture may be one of several possible species. Describe a scenario where you use Mannitol Salt agar, Blood Agar, and EMB plates to identify the unknown bacterial species. That is, how would...

Suppose you would like to determine the number of bacteria in a culture via an aerobic plate count. Explain (with pictures) how you would set up a dilution series (104, 106, 10) using the fewest number of dilution blanks. Draw and label your tubes and plates with each dilution. Show all volumes including transfers, amounts in tubes, and amounts plated 1. You want to set up a 1:10 dilution series, so that you can plate a 10-1, 102, and a...

1) A researcher discovers a new species of bacteria that obtains its energy from other organisms and its carbon from the atmosphere. This species can be categorized based upon its mode of nutrition as a: chemoheterotroph, photoautrotroph, photoheterotroph, or chemoautotroph? 2) A colony of antibiotic-resistant bacteria is mixed with a colony of antibiotic-sensitive bacteria. After a few days grown in the presence of antibiotics, all of the bacteria are resistant to the antibiotic. Which of these is most likely to...

III. You isolate a new species of bacteria that only grows in the Antarctic. A wild type strain of this bacteria can synthesize its own alanine (alat) and its own tryptophan trp' ), both of which are essential amino acids. A mutant strain of the same bacterium cannot synthesize either of those two amino acids (ala trp'). You are interested in the degree of linkage between the ala and the trp genes in this new bacterial species. Fortunately, this species...

1. Explain how culture and environment can impact development. 2. Then, imagine that you have a 3-year-old daughter who is not yet potty trained. Based on what you know and have learned about development, should you be concerned? Why or why not? 3. In 3-4 sentences, explain what the cohort effect is. 4. Then think about this - Why should we not rely on our own personal knowledge to explain human development?
