A student conducted a series of experiments with pure breeding red tomatoes and pure breeding yellow tomatoes.  The pollen from the yellow tomatoes was allowed to pollinate the stigmas of the red tomatoes. The seeds were collected and grown to determine the colour of the fruits of the first generation. All the first generation produced red fruit. The first generation plants were allowed to interbreed and the colour of the second generation fruit was determined. The results were:

red fruit = 360
yellow fruit = 119

(a) Explain why all the first generation produced red fruit.​

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
