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 Page 1 of 7

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 elements arbon, Hydrogen, Oxygen and Iron make up 7 A 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 In a well-designed scientific experiment, the question should 8 A xperimental Variable always focus on this aspect 9 A proposed, testable explanation for a scientific question Theory 10 This is the process of testing a hypothesis Hypothesis 11 The conclusion of an experiment must address if this item is either correct or incorrect xperiment 12 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 A 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 13 Page 2 of 7

3 iology 111 Lecture xam 1 This cellular structure is a critical part of protein synthesis and the structure that assembles or builds proteins A 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 mrna ellular structure that is described as selectively permeable Ribosome True or False: Select either True (A) or False () for each statement or description below 19 Most living organisms are made of cells, but some do not require cells A TRU 20 A car does not display any of the properties of life FALS 21 Living systems can transform energy from one type to another 22 Generally, a negative control involves the removal of the independent variable 23 A community has more types of organisms than an ecosystem 24 Theory of evolution by natural selection is the core theme that unifies all of biology. 25 NA and RNA are examples of these type of organic compounds A 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 Acids Page 3 of 7

4 iology 111 Lecture xam 1 True or False: Select either True (A) or False () for each statement or description below 29 Regarding NA nucleotide pairing, A s always pair with T s A TRU 30 hanges in the nucleotide sequence may alter a protein s ability to perform its normal task 31 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 FALS 34 This is a polymer made up of amino acid monomers A oth Lipids and Proteins 35 This is a polymer made up of nucleotide monomers Lipids 36 This is a polymer made up of monosaccharide monomers Proteins 37 This type of biological molecule is not a polymer arbohydrates Nucleic Acids This is a way for substances to cross the plasma membrane that does not require an additional input of energy (ATP) A 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 (ATP) Facilitated iffusion This is the movement of water down its concentration gradient and requires no additional input of energy (ATP) All of the above This is the mechanism a cell would need to use to build up a high concentration of glucose inside a cell Active Transport Page 4 of 7

5 iology 111 Lecture xam 1 43 This is a fat that has no double bonds at all A 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 46 This is a fat that has both polar and nonpolar regions Saturated Fats 47 This is a fat that has numerous kinks in it Monounsaturated Fats 48 This is the fat on the right that is the least beneficial to cardiac health 49 This is a copy of a gene in plant and animal cells A hromosomes 50 This is how NA is organized in animal and plant cells, humans have 23 types. 23 from the mother and 23 from the father hromatin 51 These are the monomers that make up NA and RNA mrna 52 This is a sequence of NA that contains the information needed to make a protein Nucleotides 53 This is a combination of NA and proteins Gene Page 5 of 7

6 iology 111 Lecture xam 1 54 This is sometimes referred to as Good holesterol A HL 55 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 58 This process occurs in organelles called mitochondria A Photosynthesis 59 This process occurs in organelles called chloroplasts Transcription 60 This is a process when mrna 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 63 This particle determines the identity (or type) of an atom A Neutron 64 Particle responsible for the total mass or atomic weight of an atom Atom 65 Particle that is part of an atom and exists in the nucleus of the atom Proton 66 Particle having mass, but no electrical charge lectron 67 This particle is responsible for determining the chemical properties of an atom 68 This particle determines the atomic number for an element Proton and Neutron Page 6 of 7
