Alarge agricultural chemical company is testing a new experimental pesticide. an unfortunate side effect in plants treated with this new product is a decrease in nadph production in the chloroplasts. (interestingly, reduction of nad+ to nadh in the mitochondria is unaffected.) given this observation, which of the answer choices would you expect to observe in the chloroplasts of these plants?

a. increase in 3.phosphoglycerate levels and a decrease in rubp levels
b. a decrease in 3.phosphoglycerate levels and an increase in rubp levels
c. an increase in glyceraldehyde-3-phosphate levels
d. an increase in 3-phosphoglycerate levels and an increase in rubp levels

Which of the following is the main purpose of a human community?

The tasmanian devil, a marsupial carnivore, is facing extinction due to devil facial tumor disease (dftd) which causes bulging cancerous lumps and lesions to erupt around the face and neck — often causing enough deformation to make seeing or eating difficult. dftd has evolved into a contagious cancer, a trait that is unique among cancers. devil mating behavior involves biting around the head and neck, allowing cells from one individual — especially cells from the crumbly dftd tumors — to be transferred to the wounds or face of a new individual. this marsupial was once found across australia, but sea levels rose, isolating the tasmanian population, while the australian population went extinct. what would be an outcome of genetic isolation that is likely to have impacted the spread of dftd? a) reduced territory puts diseased individuals in greater contact with non-diseased ones. b) inbreeding results in less variation in facial features so the cancer is generally fatal. c) genetic isolation has made it difficult for scientists to develop a vaccine against dftd. d) the lack of genetic variation in the immune system of tasmanian devils minimizes resistance to the disease.
