Independant Variable

what is manipulated or changed

Dependant Variable

thing which is affected by manipulation or change in independent variable

Positive Control

guaranteed to produce reaction from change in independent variables (so you know how the reaction actually should look like)

Negative Control

set to have no reaction; if it does, data is not valid.

you have to get 200 ul of a reagent; what do you use (micropipette, graduated cylinder, tabletop balance, analytical balance)

micropipette (P-1000)

-use smallest measuring tool

function of analytical balance

measure the mass of an object with a high degree of accuracy and precision. (measure within 0.0001 grams.)

function of tabletop balance

A tabletop balance is a scientific instrument used to measure the mass of an object. (measure till 0.01 g)

Prepare 50 ml of LB agar with a concentration of 45g/L

45g/L→45g/1000ml=C

50ml=V

C*V=M

45g/1000ml*50ml=M

2.25g=M
