John is testing the effect of temperature on the solubility of sugar in water. he plans to determine the mass of sugar dissolved in a saturated solution. he will begin with a known mass of sugar and add sugar to water until the solution is saturated. he will then calculate how much sugar dissolved by subtracting the remaining mass from the initial mass.

In a classic experiment using pea shape, mendel conducted two separate genetic crosses. in the first cross the parent plants were “true breeding” for pea shape; one had round peas ( r )and the other had wrinkled (r). the first cross produced a filial 1 generation of all round peas. in the second cross, mendel bred plants from the filial 1 generation. this cross produced different results. out of approximately 1000 plants, about 75% were round and 25% were wrinkled.
