Assuming P is purple, p is white. (So purple is dominant over white).
You didn't state the crosses so I will give you some:
1. PPxPP - all PP progeny (purple)
2. pp x pp - all pp progeny (white)
3. PP x pp - all Pp progeny (purple)
I'll put the rest in a picture, because the best way to look at these is via a Punnett Square.
The answer is: Accelerate
The answer is D. An experiment in which the outcome is repeatable.
The lac repressor functions as a tetramer and requires binding of all four sites before it releases because first it assures that the lactose level is high before the operon turns on for further steps.
<h3>
What is Lac Repressor ?</h3>
Lac repressor is a type of protein. It prevents the transcriptional stages of genes which involved in the Lactose utilization. Lac Operon binds to the DNA at a particular site which is known as Operator. Operator is the downstream of the promoter and the upstream of the site of transcription.
Lac repressor is made up of 2 DNA binding subunits which are composed of 2 monomers each and the monomers have particular 4 distinct regions.

An hypothesis is a possible explanation for a set of observations or answer to a scientific question. A supposition or proposed explanation made on the
basis of limited evidence as a starting point for further
investigation.
And practically, an hypothesis is used as the basis for further experiments, where the hypothesis is rigorously tested under varying conditions. The hypothesis that is tested and modified under different conditions may become a general
theory
.The hypothesis that has the least number of variables sufficient to explain the phenomenon is preferred.
