2 11 This type of chemical bond shares electrons A Ionic ond 12 A chemical bond that is an attraction between positive and negatively charged atoms 13 This describes the pull or attraction of an atom on its electrons Hydrogen ond ovalent and Ionic onds 14 An attraction between two polar molecules lectronegativity 15 This type of chemical bond exchanges or transfers electrons ovalent ond 16 This is the type of monomer that makes up NA and RNA A hromatin 17 Long strands of NA that exist in the nucleus. Humans have 46 of these in most of their cells hromosome 18 A substance made up of NA and proteins Gene 19 A string or segment of NA that acts as a blueprint to build a protein. Humans have about 23,000 of these Nucleotide 20 This is a protein that carries cholesterol away from our arteries A LL 21 This is sometimes referred to as ad holesterol 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 Hemoglobin HL Plasma Membrane Page 2 of 6
3 True or False: Select either True (A) or False () for each statement or description below A negative control group generally involves the removal of the independent variable for the experiment A TRU A car (automobile) displays some of the properties of life FALS 26 All living things have the ability to respond to their environment 27 Molecules are collections of two or more atoms A hypothesis is a well-substantiated explanation that is much broader in scope than a theory Viruses display a number of the properties of life, but are not considered to be alive True or False: Select either True (A) or False () for each statement or description below arbon, Hydrogen, Oxygen and Nitrogen make up the majority of matter in living organisms A TRU The formation of chemical bonds will stabilize participating atoms FALS 32 An atom that gains an electron will become slightly positive Selectively permeable cell structure that is constructed primarily of a 33 phospholipid bilayer and proteins A ytoplasm Plasma 34 The watery fluid filled interior portion of a cell membrane ellular structure found in all cells that is responsible for the 35 construction or assembly of proteins Ribosomes Structure constructed mainly out of cellulose and only found in plant 36 cells ell Wall Organelle only found in animal cells that breaks down old cellular 37 components Lysosomes This part of a cell is often found associated with the Rough ndoplasmic 38 Reticulum and gives it a bumpy appearance Page 3 of 6
4 omplex carbohydrate produced by plants and used structurally in the building of cell walls A Starch A simple carbohydrate that is also referred to as blood sugar ellulose 41 A chemical released by your pancreas to lower blood sugar Glucose 42 omplex carbohydrate produced by the liver in animals Insulin Glycogen. This set of questions pertains to the Scientific Method This step must focus on the independent variable of an experiment A Question This is a proposed explanation for a scientific question that must be testable xperiment This step must identify if the experimental hypothesis was supported or refuted by the experiment Observation This step in the scientific method is what will test the hypothesis onclusion 47 This is the first step in the scientific method Hypothesis 48 A chemical that, when dissolved in water, removes H+ ions A Acid 49 This would describe a solution with a ph of 7 ase 50 This would describe a solution with a ph of 6 Neutral 51 A chemical that, when dissolved in water, releases H+ ions uffer 52 A type of chemical that minimizes changes in ph None of the Above Page 4 of 6
5 53 This particle determines the atomic number for an element A lectron hanging the amount of this type of particle will result in different isotopes This particle is part of an atom and does not exist in the nucleus of the atom Proton Neutron 56 This particle determines the identity (or type) of an atom Atom 57 This particle is responsible for determining the chemical properties of an atom 58 Particle having mass, but no electrical charge 59 This particle has a positive charge and exists inside the nucleus 60 Atomic particles found in the nucleus of an atom Proton and Neutron True or False: Select either True (A) or False () for each statement or description below The smooth endoplasmic reticulum is the cellular location where lipids are produced A TRU The cytoskeleton is a cellular structure that assists with mechanical support and provides a track for transport vesicles to move along FALS Genetic information inside the nucleus is carried to the cytoplasm by mrna When NA nucleotides pair with other NA nucleotides, G s always pair with s Translation is the process of producing proteins Page 5 of 6
6 This is the fundamental unit of life and is the smallest entity capable of having all of life s properties A Organelle Structure or structures that are part of a cell and perform a specific function Tissue Structure or structures that are an integrated group of similar cells that work together to perform a specific function ell Structure or structures that are part of all living organisms Organ 70 Structure or structures consisting of multiple tissues that cooperate to perform a specific task Species 71 This is a fat that has both polar and nonpolar regions A This is the fat on the right that is the least beneficial to cardiac health This is a type of fat on the right that will solidify much easier at room temperature Polyunsaturated Fats Saturated Fats Monounsaturated Fats 74 This is a fat that has no double bonds at all Phospholipids 75 This is a fat that has numerous kinks in it All of the above This organelle is responsible for the process of photosynthesis in plants A Golgi omplex This organelle is responsible for carrying out any final modifications Rough ndoplasmic for proteins to be released from a cell Reticulum This is the organelle that is the location where proteins that will leave the cell are synthesized mrna This is a cellular structure that is a copy of a gene hloroplast 80 This organelle is responsible for the process of cellular respiration and the production of ATP Mitochondrion Page 6 of 6
