Question

The bacteria species known as Escherichia coli is capable of using oxygen to produce energy in a process known as respiration. It can also produce energy if no oxygen is available by using a process called fermentation. This ability is BEST described by which of these characteristics of living things?
A) use a common genetic code
B) reproduce and produce offspring
C) respond to stimuli in the environment
D) move actively through the environment

Answer 1

response to stimuli in the environment

Answer 2

The bacteria species known as Escherichia coli is capable of using oxygen to produce energy in a process known as respiration. It can also produce energy if no oxygen is available by using a process called fermentation. This ability of bacteria is its adaptability to respond to external stimuli so the correct option is C.

In the absence of oxygen, E.coli break down pyruvate from glcolysis and convert into Lactic Acid.
