Measurement Review Convert 5 miles to inches
12
Measurement Review Convert 5 miles to inches 5 miles X 5,280 feet X 12 inches =316800
13
Measurement Review Convert 5 miles to inches 5 miles X 5,280 feet X 12 inches =316800 Convert 5 kilometers to millimeters
14
Measurement Review Convert 5 miles to inches 5 miles X 5,280 feet/miles X 12 inches/foot =316800 inches Convert 5 kilometers to millimeters 5 kilograms = 5,000,000 millimeters
15
Measurement Review What do you do if you require a measurement that is less than 1 inch? 1 once?
16
Measurement Review What do you do if you require a measurement that is less than 1 inch? 1 once? Fractions

Tools Centrifuge is used to separate parts of a cell in a technique known as cell fractionation.
32
Tools Centrifuge is used to separate parts of a cell in a technique known as cell fractionation. 1) Cells are broken up by a blender
33
Tools Centrifuge is used to separate parts of a cell in a technique known as cell fractionation. 1) Cells are broken up by a blender 2) Spun at 20,000 times per minute causing organelles to separate based on density and size.
