Production Qualification Testing (PQT).
An investigation into the effectiveness of stain-removing products
I think it would be the conclusion.
The modified choke could be the control
By testing your results, and explain in your conclusion what went wrong
testing the effectiveness of lactase on lactose in varying percentages of milk (2%, skim, etc) or at different temperatures using testing strips from the drugstore.
Because otherwise you would not know what change caused the effect you noticed.
It can be, it depends on your experiment. Independent variables are the variables in an experiment that will not change. If you want to do an experiment that tests how something reacts with water, then starting with a clean controlled water sample for each test would be necessary and an independent variable. Conversely, if you were testing the cleanliness of multiple water sources, then the ideology of clean water would be your dependent variable, which would change upon each testing. WIth your given information I cannot say whether or not you would want water to be either a dependent or an independent variable for your experiment.
The control in a science experiment is the same thing as a constant. It is something that you keep the same the entire experiment. For example if you were testing how various locations affect temperature your constants would be the thermometer you used and the time for measuring the temperature. If you don't have a constant than your experiment results won't be accurate.
. Constant variables are variables which cannot be changed with the experiment. To remember their name is easy just think about Constance. They are important to an experiment because without all three variables there would be no complete experiment. Also the constant variables are important to an experiment because they help complete the result. Without a constant variable you. Would not be testing correctly
An Antonym for vaccine would be Virus
