Use the figure below to answer the following question. You plan to put in some shades that limit the wavelength of light passing through in a plant grow room to reduce the heat from too much light coming into it. If you could choose one color (i.e. wavelength) that would maximize growth, which would you pick?

Prokaryotes do not need the enzyme ___________________ because their DNA is circular not linear; hence, do not have ________________ on their ends. Your answer should consist of the first blank word with a comma and a space between them. For example: black, white

A “cell” with a selectively permeable membrane contains 0.02 M sucrose, 0.01 M glucose, 0.04 fructose, and 0 M lactose. It is immersed in a  solution consisting of 0.05 M sucrose,  0.03 M glucose, 0.01 M fructose, and 0.03 M lactose. The membrane is permeable to water and to the simple sugars glucose and fructose, but is impermeable to the disaccharides sucrose and lactose.   After waiting for almost a hour after being placed into the beaker, which of the following changes would occur?
