organism D population E ecosystem type of organism A Kingdom B Phylum C Order D Family E Species 4 When grouping organisms which classification is most general for a particular 5 During photosynthesis plants take in water and carbon dioxide from the envi ronment and use sunlight to fuel a series of chemical reactions that ultimately build small sugar molecules Which of the core concepts of biology is exemplified by photosynthesis A Evolution B Information flow exchange and storage C Structure and function D Systems E Pathways and transformations of energy and matter 6 All living organisms are composed of cells is an example of what type of scien 7 The human species is called Homo sapiens The first word refers to which taxo 8 Changes in represent the predominant cause for biological evolution tific statement A a hypothesis B a theory C a discovery D a prediction E a fact nomical grouping A Kingdom B Phylum C Order D Genus E Species A homeostasis B growth and development C reproduction D genetic makeup E energy 9 Molecules are made up of A atoms B cells C organs D organisms E populations A genome B proteome C cytoskeleton D evolution E extracellular proteins 10 Which is responsible for encoding the proteins found in a cell 11 The phenomenon through which populations of organisms change over time due to mutation natural selection and genetic exchange is A organization B reproduction Page 2 C biological evolution D growth and development E homeostasis 12 Kai is a biology graduate student who is investigating how different species of bacteria move through their environment The experiment is conducted using fluorescent labels and a special type of microscope to examine motility struc tures that extend out from the membrane Which level of study best describes her investigation A Cell biology B Molecular biology C Anatomy and physiology D Community ecology E Population ecology 13 Collecting data without a specific hypothesis in mind is called A reductionism B hypothesis testing C discovery based science D theoretical E All of the choices are correct 14 About 9 000 years ago people generated a new plant species Zea mays maize corn through the domestication of a grass known as teosinte In comparison to teosinte modern ears of corn are much larger have many more rows of corn grains have softer corn grains and do not shatter break apart to scatter the grains Which of the following most accurately describes the generation of corn A Corn was generated through natural selection because the teosinte grass naturally evolved into corn B Corn was generated through artificial selection because there was a horizon tal transfer of genes from one species to another C Corn was generated through artificial selection because people selected traits in teosinte that they deemed desirable D Corn was generated through natural selection because artificial selection re quires gene editing technologies E Corn was generated through natural selection because natural selection is the only mechanism of evolutionary change 15 Which level of organization includes all of the others in the list A cell B tissue C organ D organism E population Page 3 16 A variety of finch species within the Hawaiian Islands have acquired different types of beaks needed for utilizing specific food resources What is the likely process by which these different species of finches came about A vertical descent with mutation B horizontal gene transfer C an accumulation of harmful genetic mutations 17 In the process of biological evolution new species may evolve through exchange of genes from one species to another This process is called A proteome transfer B horizontal gene transfer C vertical evolution D vertical descent with mutation E genomic sciences 18 A researcher tests the hypothesis that large daily doses of vitamin C help protect against catching the common cold What would be the best experimental and control group to test this hypothesis A Experimental group takes a large dose of vitamin C daily Control group takes nothing B Experimental group people with a cold are administered vitamin C daily Control group people without a cold are not administered vitamin C C Experimental group takes a large dose of vitamin C daily Control group takes a large weekly dose of vitamin C D Experimental group takes a large daily dose of vitamin C Control group takes a daily dose of a sugar pill disguised as vitamin C 19 In multicellular organisms cells of the same type can associate with each other 20 All organisms in the Kingdom can perform photosynthesis to form A atoms B molecules C macromolecules D tissues E populations A Animalia B Protista C Fungi D Plantae E Bacteria Page 4 21 A researcher hypothesizes that sex in crocodiles is determined by the incubation temperature of the egg The hypothesis states that an average nest temperature of 32 33 C results in the birth of male crocodiles while cooler and warmer in cubation temperatures result in female crocodiles Researchers find a group of crocodiles in which an expanded incubation temperature gives rise to male crocodiles This particular group of crocodiles hatch male crocodiles even with incubation temperatures as low as 29 C What type of scientific approach has led to this observation A discovery based science B hypothesis testing C Both discovery based science and hypothesis testing 22 A researcher hypothesizes that crocodile gender is determined by the incubation temperature of the egg The hypothesis states that an average nest tempera ture of 32 33 C results in the birth of male crocodiles while cooler and warmer incubation temperatures result in female crocodiles What is the most likely explanation for how a group of crocodiles acquired the trait in which lower incu bation temperatures give rise to male crocodiles A Horizontal gene transfer from a related species has introduced changes in B Horizontal gene transfer from a related species has introduced changes in C One or more mutations in the genome have been passed through the group D One or more mutations in the proteome have been passed through the
