Mass determines the force of gravity like this:
If an object weight a lot it will affect the mass and gravity pulls on the object lots more when an object has lots of weight/mass.
Example: An airplane. An airplane probably weighs a ton. That is why gravity pushes it down in order for the plane to go down when it is landing or else it would be flying but never coming down. But the gravity pulling down the airplane is still there so the airplane has to be pulling the steer up in order for it to be heading straight.
Glad to help! :)
Protons are subatomic particles, their electric charge is positive, and they are located in the nucleus of the atom.
Benzoic acid is able to dissolve in hot solvents. That means that it would not be filtered out by the buchner funnel since the buchner funnel has holes in it that make it so that the solvent can get through but solids can't (the benzoic acid would be dissolved in the solvent and therefore would leave the funnel with the solvent through the holes).
Note that it is important that the solvent is hot. Benzoic acid will start to precipitate out (re crystallize) as soon as the temperature drops which will make it so that some of the benzoic acid would get caught in the buchner funnel.
I hope this helps. Let me know in the comments if anything was unclear.
Asexual reproduction only requires one parent organism. The daughter cells are copies of the original cell that divided to create the daughter cells. Sexual reproduction requires two parent organisms. The two parent cells combine to form a new unique daughter cell.
