Ascientist was observing a population of sea cucumbers in coastal waters. over a 10-day period, she collected the following information about the distribution of the individuals within a 10-meter square plot: distribution of sea cucumbers within a 10-meter square plot time of day average distance between individuals (cm) midnight 7.0 4 a. m. 7.8 8 a. m. 43.7 noon 172.0 4 p. m. 349.5 8 p. m. 58.9 midnight 7.0 use the data above as a basis as you answer the following questions: (a) identify three biotic or abiotic factors that could cause the sea cucumbers to vary their distance from each other throughout the day. (b) using one of the factors listed in part (a) as an independent variable, write a hypothesis that proposes how this variable could cause the sea cucumbers to vary their distance from each other. (c) design a procedure for a controlled experiment to test your hypothesis. (d) describe the results that would support your proposed hypothesis and the results that would refute your hypothesis.

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.

What is the best conclusion based on this data? the hypothesis was not supported because the data indicated that fertilizing plants does not improve plant growth. the hypothesis was supported; to get the best growth, use 5 milliliters of fertilizer per plant. the hypothesis was not supported; the data indicated that too much fertilizer can inhibit plant growth. the hypothesis was supported; to get the best growth, use 15 milliliters of fertilizer per plant.
