OpenStax College Concepts of Biology Supplemental Test Items TEST BANK [concepts of Biology Openstax ] Verified questions and answers OpenStax College Concepts of Biology Supplemental Test Items Test bank questions for [concepts of Biology Openstax] Chapter 01: Introduction to Biology 1. A scientist observes that when she opens the back door of her house to 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 Ite M 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 potential predator. Which of the following Most likely describes her initial observations? (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 sa Me song during those ti Mes. 3. What is the Main purpose of conducting experi Ments? (Outco Me #Ib) (DOK 1) (Paired IteM1) A. proving a theory B. Making initial observations C. disproving a hypothesis* 4. The atte Mpt to disprove a hypothesis is acco Mplished by which of the following tasks? (Outco Me #Ib) (DOK 1) (Paired Ite M 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 experi Mental design? (Outco Me #Ib) (DOK 3) (Paired Ite M 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 Concepts of Biology Supplemental Test Items 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 Missingfro M her experi Mental design? (Outco Me #Ib) (DOK 3) (Paired Ite M 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 Ite M 1) A. The creature possesses purposeful anato Mical structures that differ froM one another. B. The creature’s body is bilaterally syMMetrical.* 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 syMMetrical and consequently satisfies the criteria for defining life in which of the following categories? (Outco Me #Ic) (DOK 2) (Paired Ite M 2) A. none, syMMetry is not a basic characteristic of life* B. order C. growth and develop Ment 9. Which of the following lists correctly presents levels of organization froM siMplest to Mostco Mplex? (Outco Me #Ic) (DOK 2) (Paired Ite M 1) A. organs, organ syste Ms, organelles, organis Ms B. biosphere, atoMs, coMMunities, organis Ms C. Molecules, cells, populations, ecosyste Ms* 10. Which of the following lists correctly presents levels of organization froM Most coMplex tosiMplest? (Outco Me #Ic) (DOK 2) (Paired Ite M 2) A. cell, organelle, atoM, Molecule B. biosphere, coMMunity, organis M, organ syste M* C. Macro Molecule, population, coMMunity, 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 Concepts of Biology Supplemental Test Items B. because they have a control group C. because they are based on Many experi Mentally tested hypotheses*
