Ascientist wants to determine the best light wavelength for growing plants. he grows plants in four test groups as shown in the table below. what, if anything, was wrong with the experiment?
a. he should only grow one plant in each group.
b. he should only change the wavelength of light for each group.
c. he should add a control group with a co2 level of zero ppm and a light intensity of zero percent.
d. there is nothing wrong with the experiment.

B He should only change the wavelength of light for each group

Explanation: I just took the test and got it right

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
