44.An aspiring scientist in a biology class wanted to conduct a study on the affects of cigarette smoke on the web-building ability of spiders. Which of the following statements is an incorrect use of terms pertaining to the scientific method? A.Robert wanted to see if his theorywas true that cigarette smoke will influence web-building in spiders. B. Robert made the observationthat spiders weave webs. C. As a control, Robert had a group of spiders that were never exposed to cigarette smoke. D. Robert examined the webs from both the control group and the test group and the datawas recorded in a table. E. Robert concludedthat there was no significant difference in the ability to weave a web under conditions of cigarette smoke compared to spiders that were not exposed. Robert wanted to see if his hypothesis was true that cigarette smoke will influence web-building in spiders. A theory would need the support of many repeated experiments of this study by a large number of scientists. Bloom's Level: 5.
