given the ocular magnification on your microscope, if you use the low power objective what is the total magnification?
40x
100x
400x
1000x
question 24
1 point
which of these procedures represents poor technique in microscopy?
carry the microscope with two hands having one hand under the microscope.
always look through the ocular with both eyes.
turn the coarse adjustment and look through the microscope with high power.
ensure that the electrical cord is wrapped around the microscope when finished.

Explanation:

For Question 23: Total microscope magnification is calculated by multiplying ocular lens magnification (typically 10x for standard microscopes) by objective lens magnification. Low power objective is 4x, so $10x \times 4x = 40x$.
For Question 24: Using the coarse adjustment knob on high power risks crashing the lens into the slide, damaging both, which is poor microscopy technique. The other options are correct, safe practices.

Answer:

Question 23: 40x
Question 24: Turn the coarse adjustment and look through the microscope with high power.
