You are looking through a light microscope with a 10x eyepiece trying to
determine what type of cells you are seeing. You can only see
individual cells with 100x total magnification. What type of cell is it, and
how much detail would you expect to see?

With 10x magnification of microscope, you can see a group of cells not an individual cell because for seeing individual cell, you have a micro-scope with a magnification of 100x.

Explanation:

Cell is the basic structural and functional unit of living organisms. Cell are very tiny particles which cannot be seen through naked eyes. It can only be seen with the help of microscope. Microscope is an instrument which is used for to see very small particles which cannot be seen through eyes. Magnification is the enlargement of small picture in order to see it clearly.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
