Question
A scientist is going to perform an experiment to see how a new antibiotic affects a strain of bacteria. Which of the following pieces of equipment would be most helpful to the scientist during the experiment? A. a microscope B. a Bunsen burner C. a beaker D. a spring scale
Solution
The most helpful piece of equipment for the scientist during this experiment would be A. a microscope. Here's why:
-
The scientist is studying bacteria, which are microscopic organisms. A microscope would allow the scientist to observe the bacteria closely and see how they react to the antibiotic.
-
A Bunsen burner is used for heating and sterilizing. While it might be used in the preparation of the experiment, it's not as directly relevant to studying the effects of the antibiotic on the bacteria.
-
A beaker could be used to hold the bacteria and the antibiotic, but again, it doesn't allow for direct observation of the bacteria.
-
A spring scale is used for measuring weight or force. It's not relevant to this experiment, as the scientist is not studying the weight or force of the bacteria.
So, the microscope is the most helpful piece of equipment for this experiment.
