- What type of energy helps drive the passive processes of diffusion, osmosis, and facilitated diffusion? (Pick ALL correct statements involved with this.) In other words what are all the TRUE statements regarding these processes? Select one or more: a. random motion which increases when molecules have low molecular weight b. random motion which decreases when temperature decreases c. random motion which increases when temperature increases d. random motion which increases when molecules concentration increases e. ATP energy f. random motion which increases when molecules have large molecular weight g. random motion which increases when molecules concentration decreasesThe molecule can absorb heat from the environment without changing its chemical structure, as will occur when there is a local temperature increase. The molecule will have a higher energy. If the increase in energy is above KT (i.e., the entire environment has not increased its temperature), the molecule will come to thermal equilibrium with the environment around it, and return to its original energy state. Which one of the following is example to this? Select one: a. The absorbance of radiant energy by Melanin pigment in the skin. b. Conversion of 11-cis form of retinal to the all-trans form of retinal upon exposure to light, with a maximum absorbance at 500 nm. c. Thymine-thymine and thymine-cytosine pyrimidine bridges formation upon exposure of DNA to UV-B radiation. d.

Some of the water that you drink may eventually be converted into sweat and evaporate. If you drink a 20-ounce bottle of water that had been inthe refrigerator at 3.8 °C, how much heat is needed to convert all of that water into sweat and then to vapor?? (Note: Your body temperature is 36.6 °C. For the purpose of solving this problem, assume that the thermal properties of sweat are the same as for water.)
