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.
A)
This is not alive. It is not moving or responding.
B)
This sample is made of identical units. It is not alive.
This is a multicellular organism made of cells. It is living
D)
This may have been alive once but not now because it is not moving.

Answer 1

Answer:

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.

Answer 2

The answer I think would be D !
