Under what conditions might you expect to find living growin

Under what conditions might you expect to find living growing cells? There is more than one correct choice, select all that apply to receive credit. In seawater at a temperature of -1 degrees C. At temperatures of more than 150 degrees C. At a a pH of 2.0 In a brine composed of 20% NaCl. A temperature of 115 degrees c at a deep sea hydrothermal vent. In the absence of oxygen. In the absence of water.

Solution

Answer:

Below all are the correct choices:

1. In sea water at a temperature of -1°C - In Antarctica where temperatures are extremely low, algae and diatoms have been found (psychrophiles)

2. At a pH of 2.0 - acidophiles are capable of growth and reproduction in extreme conditions where pH is less than

3. In a brine composed of 20% NaCl: Alkaliphiles can grow and reproduce under extreme alkaline conditions

4. At a temperature of 115°C at a deep sea hydrothermal vent - hyperthermophiles can grow and reproduce in such conditions e.g pyrococcus furiosus

5. In the absence of oxygen - anaerobic organisms can grow and reproduce
