A sealed bottle containing bacteria cells and nutrients needed for cell growth is exposed to intense heat. It is then cooled. The bottle is not opened. Once the bottle has cooler, scientists note that even after several weeks, no bacteria growth occurs in the bottle. What can correctly be concluded from the experiment ? A. New cells can only form from existing, living cells
B. New cells can only form in the presence of nutrients.
C. New cells can form from nonliving materials
D New cells can only form from nutrients if energy is provided

1.aluminum chloride (alcl3), and sodium hydroxide (naoh) can react to form aluminum hydroxide (al(oh)3) and sodium chloride (nacl).    you have 13.4 g of aluminum chloride and 10.0 g of sodium hydroxide. answer the following questions: •what is the balanced equation for this reaction? •if you use all 13.4 g of aluminum chloride, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •if you use all 10.0 g of sodium hydroxide, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •how many grams of aluminum hydroxide will actually be made?     which reagent is limiting? explain your answer.

0.09 moles of sodium sulfate in 12 ml of solution

If you chip a tooth, most likely you will go to the dentist to have the missing material filled in. currently the material used to fill in teeth is a polymer that is flexible when put in, yet is hardened to the strength of a tooth after irradiation with blue light at a wavelength of 461 nm. what is the energy in joules for a photon of light at this wavelength?
