Answer:

1.b-low powder objective

2.c-cover slip

Explanation:

-ALWAYS START WITH THE LOW POWER OBJECTIVE! Memorize this. Low power lens gives the widest field of view and makes it easier to find the specimen when you look through the microscope. Finding the specimen at high power, without first centering it in the field of view at low power, is nearly impossible.

-When viewing any slide with a microscope, a small square or circle of thin glass called a coverslip is placed over the specimen. It protects the microscope and prevents the slide from drying out when it's being examined.
