Question
Several statements are listed below.
For each statement, determine and justify whether it is a testable hypothesis.
a) “If you turn out all the lights, you will fall asleep much faster.”
( Is it a testable hypothesis? Yes or No )
b) “If the size and shape of the molecules are related to the rate of diffusion as they pass through a membrane, then larger and more linear, polar molecules will flow through at a lower rate.”
( Is it a testable hypothesis? Yes or No )
c) “If I cover the perspective anti-cancer drug with a non-polar coating for easier penetration through the cellular membrane then I can treat cancer with lower quantity of the drug and the drug will be acting more efficiently.”
( Is it a testable hypothesis? Yes or No )
d) “A feather and a hammer will fall with the same acceleration if dropped from the same height on the Moon.”
( Is it a testable hypothesis? Yes or No )
Explanation / Answer
a).“If you turn out all the lights, you will fall asleep much faster.”
Answer No it is not a testable hypothesis.
The amount of sleep and how much faster you are falling asleep cannot be measured by relating it to turning off the lights.
b). “If the size and shape of the molecules are related to the rate of diffusion as they pass through a membrane, then larger and more linear, polar molecules will flow through at a lower rate.
Answer Yes it a testable hypothesis.
The rate of diffusion can be measured and compared for polar ,larger and linear molecules.
c).“If I cover the perspective anti-cancer drug with a non-polar coating for easier penetration through the cellular membrane then I can treat cancer with lower quantity of the drug and the drug will be acting more efficiently.”
Answer No it is not a testable hypothesis.
d) “A feather and a hammer will fall with the same acceleration if dropped from the same height on the Moon.”
Answer Yes it a testable hypothesis.
The acceleration ,the height of fall of both the feather and hammer could be measured.
