Javier has found a beetle during a field study. he suspects that it might be a new species of beetle that no one has ever documented before. he takes the beetle back to his lab and examines it under a microscope. what does javier need to do so that he can accurately compare his beetle to known species of beetle? a. javier must carefully record and describe all of the characteristics of his beetle. b. javier must carefully record and describe the beetle's response to laser light. c. javier must collect some of the beetle's tissue so it can be cloned. d. javier must compare the beetle's foot speed to that of ant.

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
