Question

escherichia coli, or e. coli, is a species of bacteria. entamoeba histolytica, or e. histolytica, is a single - celled amoeba. what do e. coli and e. histolytica have in common? select all that apply
a they depend on sources of energy or food
b they are unable to respond to changes in their environment
c they maintain homeostasis by cell specialization
d they reproduce

Explanation:

• Option A: All living cells, including prokaryotic (E. coli) and eukaryotic single-celled organisms (E. histolytica), need energy/food to carry out metabolic processes.
• Option B: Both organisms are living and can respond to environmental stimuli (e.g., E. coli moves toward nutrients, E. histolytica responds to food sources), so this is false.
• Option C: Cell specialization occurs in multicellular organisms; these are single-celled, so they use their single cell for all homeostasis tasks, making this false.
• Option D: All living organisms reproduce; E. coli reproduces asexually via binary fission, and E. histolytica also reproduces asexually.

Answer:

A. They depend on sources of energy or food
D. They reproduce
