Which of the following correctly describes the role of rubisco in the calvin cycle? a) rubisco uses atp to regenerate rubp. b) rubisco incorporates co2 from the atmosphere into an organic molecule. c) none of the other answer options is correct. d) rubisco uses nadph to reduce 3-phosphoglycerate to a three-carbon sugar.

The correct answer is B) Rubisco incorporates CO2 from the atmosphere into an organic molecule

RuBP oxygenase-carboxylase or rubisco enzyme is an enzyme that acts during the first stage of the Calvin cycle (light-independent or dark reactions of photosynthesis). Its role is in the process of carbon fixation where rubisco incorporates carbon dioxide into an organic molecule (CO2 combines with a five-carbon acceptor molecule, ribulose-1,5-bisphosphate – RuBP).

Besides of using CO2 as a substrate, rubisco sometimes uses O2.  This is a reaction called photorespiration, which leads to the loss of already-fixed carbon, waste of energy and decrease in sugar synthesis.

meiosis is the first to occur after the nuclei of opposite of opposite mating types fuse

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
