Apanda has a diet of bamboo leaves over a certain time period. the amount of energy available in the food consumed by the panda was 600 j. of this energy, 220 j was lost as undigested material in the panda's feces. the amount of chemical energy in the food that the panda converted to its own new biomass (using it for growth) was 348 j. using the following equation, calculate the difference between the assimilation of primary production and the net secondary production in this description. (1 point) production efficiency = (net secondary production x 100%) / (assimilation of primary production) 1 32 252 380

Mr. j, age 42, is a construction worker in las vegas. he recently noticed that a mole on his face seemed to be getting larger and darker. at first he did not worry because he was in the sun a lot and assumed the change may have been caused by sunburn. after a month, not only was the mole larger and darker, but it appeared to be “bumpy.” his doctor diagnosed a malignant melanoma skin cancer following biopsy of the nevus. mr. j reports pain in his right shin that does not go away when he puts his feet up or sleeps. discussion questions 1. relate mr. j’s skin changes to the warning signs for malignant melanoma.

3. in the fruit fly, recessive mutation brown, b, causes brown color of the eye and absence of red pigment. recessive mutation p of another independent gene causes purple color of the eye and absence of brown pigment. the cross of a brown-eyed female and purple-eyed male produced wild type eyes. what will be the colors and their ratio in f2?
