Wanda and Marita are drinking bottles of water. Each girl sounds a different musical note by blowing across the top of her bottle. What is a good hypothesis that could lead to new experimentation?

It is more fun to play musical notes with carbonated water than with normal spring water.
If the lid on a bottle is tightly closed, then blowing across the top of the bottle will not make a musical note.
Blowing across the top of a bottle can make a musical note.
If there is less water in the bottle, then the note played is lower because there is more air to move around.

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?
