Question

Carol and Sam were using the microscope in science class. They used a dropper to put some pond water on their microscope slide. This is what they saw. "That is something living," said Sam. "I don't think so," said Carol. What do you think? Explain.

Answer 1

Sam was actually correct. Pond water usually contains microrganisms like bacteria, viruses, and parasites. This is also why people do not drink pond water without getting rid of the impurities.

Answer 2

Step-by-step explanation:

I think Sam is right because pond water can be full of impurities which can include many microorganisms such fungi, bacteria, protozoa, etc. For example, there is high possibility that the pond water sample collected by Sam and Carol would contain traces of blue-green algae which is also a living organism as it uses sunlight to prepare its own food.
