The cold air increases pressure on the basketball, causing it to appear flat. When it warms up that pressure is taken off, so the basketball is at it's normal state.
The product of (wavelength) times (frequency) is always
the same number ... it's the speed of the wave.
So if the speed of the wave doesn't change, the product
of (wavelength) times (frequency) doesn't change.
That means that if the wavelength OR the frequency changes,
the OTHER one has to change by the same factor in the opposite
direction, in order to keep their product unchanged.
If the frequency in INcreased by a factor of 4,
the wavelength must DEcrease by a factor of 4.
If the frequency becomes 4 times as great as it was,
then the wavelength becomes 1/4 as long as it was.
(Please don't say "4 times shorter". That's meaningless and I hate it.)

Photosynthesis, ice melting, cooking an egg, and baking a cake are 5 endothermic reactions going on around me.
Answer:
I believe cells do have different types of openings. I think this way because unlike doors cells can open up to different types of organs in your body like your heart, liver, and lungs.
