Homework Answers
Staphylococcus bacteria are an opportunistic pathogen which can survive under extremes salt, pH, temperature, and desiccation due to following features:
- It has ability to be extremely changed in the unfavorable osmotic pressure conditionsdue to various osmoprotectants like choline, betaine, as well as proline
- The salt tolerance occurs due to its genetic composition of brnQ and arsR (arsenic operon regulator gene). The cardiolipin contents fascilitate it to be salt tolerant
- Also the phospholipid content of the Staphylococcus bacteria enables it to flourish in the condition of the pH, temperature, dessication and osmolarity change.

- 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...

Describe the environmental conditions that extremophiles are able to live in. Extremophiles were microbes that could only live in conditions that prevailed early in Earth's history when environments had high temperatures and pressure and lacked oxygen. Extremophiles includes those microbes that thrive in very high-salt, high-temperatures, low-temperature, high-pressure, low-pH, or high-pH harsh conditions. O Extremophiles can only survive in habitats where there are extreme changes in close proximity, such as hydrothermal vents at the bottom of the ocean, where water...

Exploring Salt Marsh Ecosystems Please answer all questions 1.) What is the difference between spring tides and neap tides in terms of relative tide heights? What regions of the marsh (high, mid, low) are inundated (flooded) with water during the respective high tides (neap vs. spring)? 2.) How does the biodiversity change in different regions of the marsh? How does the frequency and severity of disturbance to each of the regions influence the biodiversity trends you observed? 3.) What natural...
