The graph below illustrates the growth curves for two types of bacteria, A and B, as the pH of their surrounding mediums change.
pH of 0-7 = acidic pH pf 7-14 = alkaline/basic pH 7 = neutral
What is true of Bacteria A?
a
Bacteria A grows best in a medium that is slightly basic.
b
Bacteria A grows best in a medium that is very basic.
c
Bacteria A grows best in a medium that is neutral.
d
Bacteria A grows best in a medium that is slightly acidic.
d
Bacteria A grows best in a medium that is slightly acidic.
Based on the provided information, the correct answer is option d: Bacteria A grows best in a medium that is slightly acidic.
To answer this question, you need to analyze the graph provided. Look for the growth curve of Bacteria A and observe at which pH level it shows the highest growth rate.
If the graph shows a peak growth rate for Bacteria A at a pH level between 7 and 14, it means that Bacteria A grows best in a medium that is alkaline/basic. Therefore, the correct answer would be:
Option b: Bacteria A grows best in a medium that is very basic.
You can arrive at this answer by analyzing the graph and identifying the highest point on the growth curve for Bacteria A, which corresponds to the pH level at which it exhibits the highest growth rate.
