Answer:
roots, shoots, fruit, wild celery, and tree bark and pulp
Explanation:
A biologist wants to know whether a plant's growth is affected by the material it's planted in. She plants lima bean seeds in a jar of dirt, a jar of cotton, and a jar of rocks, then provides each jar with equal amounts of water, plant food, and sunlight. In this experiment, the independent variable is the material in which the plant is getting planted.
The independent variables are the variable that are in control of the experimenter. The independent variables do not depend on the other variable for their selection. The changes in a dependent variable is studied by varying the independent variable accordingly.
The right answer is B.
The operator is the segment of DNA to which a chemical signal (a regulatory molecule) binds. It can be either a repressor signal or a transcription activating signal (DNA operator) or translation (RNA operator) of the genes of the operon.
In the case of loperon lactose, the operator is located downstream of the promoter so that it can regulate the trancription. In the case of this experiment, the promoter has been removed from the opterator, and in this case, can no longer regulate the transcription, and therefore the synthesis will be continuous (unregulated).
Another interesting fact is that beta galactosidase will not be transcribed since it will be positioned upstream of the promoter (so the E response is false).
