Question

Bacteria are very tiny living organisms. Trisha wants to study how bacteria respond to light.
Which of the following pieces of equipment will she most likely need to use for her investigation?

a spring scale

a meter stick

a telescope

a microscope

Answer 1

I would guess microscope. Both a spring scale and a meter stick are large a used to measure the dimensions and weight of something. A telescope is used mainly for looking at the sky/stars so microscope is the best answer.

Answer 2

@quesmith microscopes are also used for examining really small (microscopic) organisms.
