This is the seed dispersal method of the Maple Tree, I call them helicopters. When they fall from the tree their shape allows them to spin, hopefully away from the parent tree. They also make a lovely rhinoceros nose.
Animal that has a segmented body
As you can see, this is an earthworm. Like many worms, this little fella is segmented. If you recall back to our lab last year, when you cut them open there are continuous rings along their sides, about a millimeter apart, the entire way down their body.
Hydrophobic
The molecules of this canola oil are non polar. Because water is polar, they do not mix well and it can be said that oil is hydrophobic.
Hydrophilic
Almond extract is a solution with the solvent being alcohol. Alcohol is a polar molecule, making the solution largely polar. This allows it to easily mix with water; it is hydrophilic.
Ethylene
Ethylene is a gas produced by plants which can stimulate growth, petal loss, and ripening of fruit. It is part of the reason that this nectarine ripened when placed in a bowl of fruit.
