10)

If the bottom of the meniscus in a 10 ml pipet is at 3 ml, how many ml of liquid is in the pipet? Answer: 7 (seven) Explanation: If a 10 ml TD (to dispense) pipet is full, the meniscus of the fluid is at the zero line on the pipet, and the pipet contains 10 ml of fluid. If the bottom of the meniscus is at the 3 ml line, then 3 ml have been dispensed and the pNipUeRt ScIoNnGtaTiBn.sC7OMml of fluid.

11) Rank the values of these metric prefixes from smallest to largest.

? Kilo ? Milli ? Deka ? Deci

Answer: Milli, Deci, Deka, Kilo Explanation: The values of these prefixes are as follows: Milli = 1 ? 10-3 Deci = 1 ? 10-1 Deka = 1 ? 101 Kilo = 1 ? 103 Section: The Metric System Topic: A View of Life; Measurements in Biology Learning Objective: 02.02.

12) The linear space occupied on your lab tray by the pipets that you will use for lab measures 25

cm long and 5 cm wide. What is the correct way to refer to the area occupied by the pipets?

A) 5 cm



B) 5 cm2

C) 125 cm

D) 125 cm2

E) 0.04 cm3

F) 0.04 cm2

Answer: D Explanation: Area is calculated by multiplying two linear measurements. The units of area are units of length squared. 5 cm ? 25 cm = 125 cm2 .
