Reаd the fоllоwing pаssаge and see the figure belоw. This is question 1 of 2 about this passage and figure. “The popular herbicide atrazine induces a compound that converts testosterone into estrogen. Researchers wanted to know whether the survival of some amphibian species could be at risk due to atrazine’s effects on the number, function, and fertility of males. In Hayes et al. (2002), researchers tested the hypothesis that atrazine reduces testosterone levels in male frogs by exposing one group of 90 male frogs to 25 parts per billion (ppb) atrazine every 3 days for 46 days. A group of 90 control males and a group of 90 control females were treated identically to the atrazine-treated group, except they were not exposed to atrazine. All frogs were housed individually and fed Purina rabbit chow. After 46 days, individual testosterone levels were measured in frogs from each group. The results are below.” QUESTION: What is a controlled variable in this experiment?
Pleаse sit аt а table in a brightly lit rооm with nо materials around you, and no head covering or head/earphones. And you may not read questions out loud. All electronic devices except your computer (being used to take the Bio3 Midterm) must be turned off and placed away from the test taking area. No outside aids or resources are allowed. You are not allowed to use your notes, textbook, or any other resource. You are not allowed to communicate with any other human being (other than the Honorlock proctor) while taking this exam. Please keep your HANDS in view of the camera during pauses while reading questions or thinking!! Prolonged pauses while your hands are not shown will indicate that you are trying to look answers up on a device. This will result in a flag and a ZERO for the exam. You may not share, disseminate, or discuss these questions with any other student in another section of this course who has not taken the exam yet; doing so is considered academic dishonesty and will lead to nullification of exam grades. This assessment may not be posted online or disseminated by any means. There will no tolerance towards academic dishonesty, and cheating can and will lead to automatic failure from the class as well as a report to the Academic Integrity Committee. You must sign the statement below on academic integrity for this exam to be graded. My signature below constitutes my pledge that I have followed Mount Saint Mary's University policy on academic integrity as well as the specific instructions for this exam. I affirm that this exam represents my own work, without the use of any un-permitted aids or resources. I understand that there will be no tolerance towards academic dishonesty and cheating. If the proctoring system (including the recorded video) confirms that I was not following the test taking protocols or was acting in a suspicious manner, the video evidence will lead to an automatic failure for this exam as well as a report to the Academic Integrity Committee. I understand that failing to use the SIDE CAMERA as required will result in a zero. Please enter your name and the date in the response blank to affirm the above:
