in corn height within each field could differ between

corn and the varia-
tion in corn height
within each field
could differ be-
tween fields

In pea plants, flowers are either white or purple; the
purple color is produced by pigment called antho-
cyanins. The production of anthocyanins is a two step
process the first is controlled by the C gene and the
second by the P gene both genes must be produced

Seedings were germinated on moist paper towels at 20°C for 48 hours. Oxygen consumption of the two-day-old seedlings
was measured at different temperatures. The data are shown in the graph below.

Describe the exact set-up of the experiment to a Brassica rapa plant for a lighting experiment with natural sunlight and artificial lighting including how many plants you started with, what the seeds were planted in, if anything was added to the environment, etc.
Describe in detail how to measure the Brassica rapa.
Describe the variables that were held constant. Specifically, address the difference between the control groups versus experimental groups and how exactly you applied an independent variable which is the duration of light exposure of the Brassica rapa to the experimental group members. Quantify the independent variable.
