How would you be able to construct a hypothesis regarding the food colouring dye samples?
Like how would you be able to make a scientific guess on which food colouring dye would migrate the furthest? I have researched and I know that different colours mean that the molecules the samples are made up of are different, but I don't know the scientific evidence to back it up, like if a certain colour would have…

COVID/Vaccines / Computational Biology Project
COVID/Vaccines / Computational Biology Project

What I want to do this year is expand on different age groups and possibly create software that would represent what different cells for different age groups look like when they get infected with COVID-19. This project is a three-year project.…

Help! Ovotransferrin impacts bacteria growth
Help! Ovotransferrin impacts bacteria growth
Hi,

Additionally, since I don't have the proper equipment to extract ovotransferrin from egg white, I plan on doing a rescue…

Drug Solubility
Drug Solubility
How would I measure and test the solubility of drugs like pain-relievers? I researched a little on how to do it, but everything requires expensive lab equipment that neither I, or my school have. Is there some other way to test drug solubility that isn't as expensive? Also, how would I measure the solubility?

We say that when a stationary train suddenly starts we tend to get a jerk back wards. As they say, it's due to inertia of rest (as the body needs to be brought in motion from rest)
Now my question is,
I don't get the fact that, how can we say that when the train is in motion, The body too is in motion. I mean, even after a jerk we continue to be in one place until we move by ourselves. I don't see any difference before and after the jerk as the body is still at…
