A scientist observes that when she opens the back door of her house t o let her cat out, the songs of a certain species of bird abruptly change. She wants to follow up on her observations with an infor Mal experi Ment. Which of the following is the best hypothesis for explaining the birds’ song changes? (Outco Me #Ia) (DOK 2) (Paired IteM 1) A. The bird species switches froM song to warning call whenever it sees a potential predator.* B. The bird species has a variety of songs that it sings, regardless of what is happening in its environ Ment. C. The scientist is Mistaken and the songs do not change. 2. A scientist wants to test the hypothesis that a certain bird species in her back yard changes its songs to warning calls whenever it detects the presence of a pote ntial predator. Which of the following Most likely describes her initial observa tions? (Outco Me #Ia) (DOK 2) (Paired IteM 2) A. The scientist noticed that whenever she opened a door to her house, she heard birds beginning to sing. B. Each tiMe the scientist let her cat outside, the birds abruptly changed their songs.* C. The scientist noticed that the birds only appeared at certain tiMes of the day, always singing the saMe song during those tiMes. 3. What is the Main purpose of conducting experi Ments? (Outco Me #Ib) (DOK 1) (Paired IteM 1) A. proving a theory B. Making initial observations C. disproving a hypothesis* 4. The atteMpt to disprove a hypothesis is acco Mplished by which of the following tasks? (Outco Me #Ib) (DOK 1) (Paired IteM 2) A. conducting experi Ments* B. Making initial observations C. proposing a theory 5. A scientist wishes to test a new antibiotic’s ability to treat stubborn bacterial infections. He tests his hypothesis that the antibiotic works better than existing treat Ments by giving bacterial infections to Mice and treating theM with the antibiotic. He then deter Mines how Many of the Mice recover fro M their infections. What is Missing fro M his exp eriMental design? (Outco Me #Ib) (DOK 3) (Paired IteM 1) A. He is Missing a control group of Mice that received a half dose of the new antibiotic. B. He is Missing a control group of Mice that did not receive the new antibiotic.* OpenStax College Concept s of Biology Supplemental Test Items Chapter 01: Introduction to Biology C. Nothing is Missing —he has done everything he needs to do for this to be a successful experi Ment. 6. A scientist wants to deter Mine whether a new che Mical she isolated can cure a certain disease. To test her hypothesis that the new cheMical cures the disease More effectively than current treat Ments, she infects Mice with the disease and gives the M the new cheMical. She then assesses how Many Mice were cured of the disease. What is Missing froM her experi Mental design? (Outco Me #Ib) (DOK 3) (Pair ed IteM 2) A. She is not Missing anything —her experi Mental design is adequate to test her hypothesis. B. She is Missing a control group of Mice that received a half dose of the new cheMical. C. She is Missing a control group of Mice that did not receive the new cheMical.* 7. A scientist believes that she has found a new life forM. Which of the following conditions is not considered essential in deter Mining whether the putative new life for M is alive? (Outco Me #Ic) (DOK 2) (Paired IteM 1) A. The creature possesses purposef ul anato Mical structures that differ froM one another. B. The creature’s body is bilaterally syMM etrical.* C. The creature seeMs to react to being touched. 8. A scientist discovers a putative new life forM and notes that the creature’s body is bilaterally syMM etric al and consequently satisfies the criteria for defining life in which of the following categories? (Outco Me #Ic) (DOK 2) (Paired IteM 2) A. none, syMM etry is not a basic characteristic of life* B. order C. growth and develop Ment 9. Which of the following lists correct ly presents levels of organization froM siMplest to Most coMplex? (Outco Me #Ic) (DOK 2) (Paired IteM 1) A. organs, organ syste Ms, organelles, organis Ms B. biosphere, atoMs, coMM unities, organis Ms C. Molecules, cells, populations, ecosyste Ms* 10. Which of the following lists correctly presents levels of organization froM Most coMplex to siMplest? (Outco Me #Ic) (DOK 2) (Paired IteM 2) A. cell, organelle, atoM, Molecule B. biosphere, coMM unity, organis M, organ syste M* C. Macro Molecule, population, coMM unity, ecosyste M 11. An “educated guess” as to what causes an observed pheno Menon is known as a: (Outco Me #1) (DOK 1) A. theory B. hypothesis* C. control 12. Why are theories stronger and More reliable than hypotheses? (Outco Me #1) (DOK 2) A. because we believe in theM More OpenStax College Concept s of Biology Supplemental Test Items Chapter 01: Introduction to Biology B. because they have a control group C. because they are based on Many experi Mentally tested hypotheses*
