Multiple Choice
Bacteria that grow in mine drainage at pH 1-2 are probably which of the following?
A
Neutrophiles
B
Alkaliphiles
C
Acidophiles
D
Halophiles
Verified step by step guidance
1
Identify the environmental condition described in the problem: the bacteria grow in mine drainage at a very low pH of 1-2.
Understand the pH scale: pH is a measure of the acidity or basicity of a solution. A pH less than 7 is acidic, a pH of 7 is neutral, and a pH greater than 7 is basic (alkaline).
Recognize the terms: Neutrophiles prefer neutral pH environments, Alkaliphiles thrive in basic environments, and Halophiles are adapted to high salt concentrations.
Define Acidophiles: These are organisms that thrive in highly acidic environments, typically at pH levels below 3.
Conclude that bacteria growing in mine drainage at pH 1-2 are likely Acidophiles, as they are adapted to survive and grow in such acidic conditions.
