unit 1: scientific notation constructed response assignment
number properties. explanations, according to the scientific notation constructed response assignment rubric. completely respond to all parts below. when you have finished, submit your completed assignment to the unit 1: scientific notation constructed response assignment folder in your math oms course.

the diameter of the average cell in the human body is 1 x 10-5 meters. the diameter of a grain of sand is about 2 x 10-4 meters. the diameter of a human hair is about 0.25 meters.

part a (2 points): what is the diameter of a human hair written in scientific notation?

part b (2 points): how many times longer is the diameter of a grain of sand than the diameter of the average cell in the human body? show your work.

part c (2 points): given that 1 meter = 1 x 109 nanometers, what is the diameter of the average cell in the human body, in nanometers? show your work.

part d (2 points): the smallest known bacteria are from the genus mycoplasma and can measure as small as 300 nanometers in diameter. given that 1 meter = 1 x 109 nanometers, what is the diameter of the smallest bacteria, in meters? give your answer in scientific notation and show your work.

part e (2 points): very small numbers are often written in exponential form using scientific notation to make them easier to multiply or divide. explain how to apply the laws of exponents when multiplying and dividing numbers written in scientific notation
