Question

select the correct answer
a stream of water holds thriving bacteria. if drought conditions caused the stream to dry up, how would the bacteria most likely respond to survive?
a. they would learn how to photosynthesize.
b. they would produce more peptidoglycan.
c. they would secrete more polysaccharides.
d. they would produce endospores

Explanation:

Bacteria in drying environments often form dormant, tough structures called endospores to survive extreme conditions like drought. Photosynthesis is not a trait most stream bacteria can suddenly acquire. Peptidoglycan strengthens cell walls but does not protect against complete desiccation, and extra polysaccharides do not provide the same long-term survival mechanism as endospores.

Answer:

D. They would produce endospores
