2 iology 111 Lecture xam 1 Matching: Select the statement (on the right) that responds to the instructions on the left. # Instructions Letter Statements Select the statement on the right that is FLS hromosomes are made of compacted chromatin Nuclear Pores control the passage of chromosomes in and out of the nucleus 14 Most cells in the human body two sets of 23 chromosomes Genes are lengths of N that are located on chromosomes Strands of human N are broken into shorter segments called chromosomes 15 This is a group of interacting individuals of one species iosphere This consists of all life on arth and all the environments that support life. This is the broadest and most inclusive of levels of biological organization This consists of all the interacting populations of organisms occupying an ecosystem. This includes all the living organisms in one particular area as well as the nonliving components that affect life cosystem ommunity Population Organisms Matching: Select the statement (on the right) that responds to the instructions on the left. # Instructions Letter Statements Select the statement on The elements arbon, Hydrogen, Oxygen and Iron make up the right that is TRU the majority of matter in organisms arbon, Iron and Zinc are essential to life and are known as trace elements The elements arbon, Hydrogen, Oxygen and Nitrogen make up the majority of matter in organisms arbon, Hydrogen, Oxygen and Nitrogen are essential to life and are known as trace elements The elements Phosphorous, Zinc, Nitrogen and Iron make up the majority of matter in organisms 20 Page 2 of 7

3 iology 111 Lecture xam 1 In a well-designed scientific experiment, the question should always focus on this aspect xperimental Variable proposed, testable explanation for a scientific question Theory 23 This is the process of testing a hypothesis Hypothesis 24 The conclusion of an experiment must address if this item is either correct or incorrect xperiment 25 This is the third step in the Scientific Method Observation Matching: Select the statement (on the right) that responds to the instructions on the left. # Instructions Letter Statements Select the statement on The attraction between two polar molecules is called an ionic the right that is TRU bond If two atoms form a bond and they have identical electronegativities they will form a covalent bond If two atoms form a bond and they have identical electronegativities they will form a ionic bond If two atoms form a bond and they have very different electronegativities they will form a covalent bond If two atoms form a bond and they have identical electronegativities they will form a hydrogen bond 26 This cellular structure is a critical part of protein synthesis and the structure that assembles or builds proteins Golgi omplex This cellular structure is a critical part of protein synthesis and is a copy of a gene Plasma Membrane ellular structure that is a network of tunnels or tubes and is a Rough ndoplasmic location for protein synthesis in the cell Reticulum ellular structure that adds final modifications to proteins to be exported from the cell mrn ellular structure that is described as selectively permeable Ribosome Page 3 of 7

4 iology 111 Lecture xam 1 32 N and RN are examples of these type of organic compounds ellulose, lactose and glucose are examples of this type of organic compound oconut oil, holesterol and Triglycerides are this type of organic compound Hemoglobin, Hexokinase and Keratin are examples of this type of organic compound oth Lipids and Proteins Lipids Proteins arbohydrates Nucleic cids True or False: Select either True () or False () for each statement or description below 36 Regarding N nucleotide pairing, s always pair with T s TRU 37 hanges in the nucleotide sequence may alter a protein s ability to perform its normal task 38 In comparing plant and animal cells, only plant cells have lysosomes hanges in the amino acid sequence may alter a protein s ability to perform its normal task The cytoskeleton is a system of protein fibers that perform various function within an animal cell FLS 41 This is a polymer made up of amino acid monomers oth Lipids and Proteins 42 This is a polymer made up of nucleotide monomers Lipids 43 This is a polymer made up of monosaccharide monomers Proteins 44 This type of biological molecule is not a polymer arbohydrates Nucleic cids Page 4 of 7

5 iology 111 Lecture xam 1 This is a way for substances to cross the plasma membrane that does not require an additional input of energy (TP) Osmosis This is a way for substances that relies on a concentration gradient to power it, as well as a transport protein Simple iffusion This is a way for substances to cross the plasma membrane that requires an additional input of energy (TP) Facilitated iffusion This is the movement of water down its concentration gradient and requires no additional input of energy (TP) ll of the above This is the mechanism a cell would need to use to build up a high concentration of glucose inside a cell ctive Transport This is a fat that has no double bonds at all Phospholipids This is a type of fat on the right that will solidify much easier at room temperature This is the fat on the right that is the most beneficial to cardiac health Polyunsaturated Fats Trans Fats 53 This is a fat that has both polar and nonpolar regions Saturated Fats 54 This is a fat that has numerous kinks in it Monounsaturated Fats 55 This is the fat on the right that is the least beneficial to cardiac health Page 5 of 7

6 iology 111 Lecture xam 1 56 This is a copy of a gene in plant and animal cells hromosomes 57 This is how N is organized in animal and plant cells, humans have 23 types. 23 from the mother and 23 from the father hromatin 58 These are the monomers that make up N and RN mrn 59 This is a sequence of N that contains the information needed to make a protein Nucleotides 60 This is a combination of N and proteins Gene 61 This is sometimes referred to as Good holesterol HL 62 This is a protein that carries cholesterol into our arteries Heart holesterol is an important part of this structure and helps to keep it in a fluid state The center part of this structure consists of nonpolar (hydrophobic) fatty acids LL Hemoglobin Plasma Membrane 65 This process occurs in organelles called mitochondria Photosynthesis 66 This process occurs in organelles called chloroplasts Transcription 67 This is a process when mrn is created in animal and plant cells This process involves the transformation of energy from one form to another form This is a process when monomers are assembled into proteins for both plant and animal cells Photosynthesis and ellular Respiration ellular Respiration Translation Page 6 of 7
