3) What are the magnification abilities of each of the objective lenses? What is the total magnification with each objective?
a) Scanning (small lens ), red ring =
b) Low-power ( medium lens ), yellow ring =
c) High-power ( large lens ), blue ring =
d) Oil immersion ( largest lens ), white ring =

where is the following

explanation:

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
