front 1 What is an element? | back 1 A fundamental item that can't be easily broken down further |
front 2 What is a molecule? | back 2 A group of elements bonded together |
front 3 What is a compound? | back 3 Chemical substances made up of two or more elements that are chemically bound together in a fixed ratio |
front 4 What is an independent variable? | back 4 A variable that stands alone and isn't changed by the other variables you are trying to measure |
front 5 What is a dependent variable? | back 5 What you measure in the experiment and what is affected during the experiment |
front 6 What is quantitative data? | back 6 Measures of values or counts and are expressed as numbers |
front 7 What is qualitative data? | back 7 Data representing information and concepts that are not represented by numbers |
front 8 What is objective data? | back 8 Fact-based data that is both measurable and observable |
front 9 What is subjective data? | back 9 Subjective data comes from feelings, experiences, opinions, and thoughts |
front 10 What is a polar molecule? | back 10 Molecules that have a dipole or an uneven distribution of charge across their geometry resulting in one side being positive and the other side negative |
front 11 What causes a molecule to become polar? | back 11 Unequal distribution of the negatively charged electrons in the orbitals of the molecule |
front 12 What role does hydrogen bonding play in the main properties of water? | back 12 Hydrogen bonds between water molecules give water its high boiling point, high heat capacity, and surface tension |
front 13 What are the monomers, main functions, and examples of carbohydrates? | back 13 Monosaccharides/ Carbon 2 Hydrogen and one oxygen molecule, the main source of energy for your body's cells, tissues, and organs, sugars, starches, and fiber. |
front 14 What are the monomers, main functions, and examples of lipids? | back 14 Glycerol and fatty acids, move and storing energy, absorb vitamins and make hormones, steroids, phospholipids |
front 15 What are the monomers, main functions, and examples of amino acids? | back 15 Amino acids are a monomer, they make peptide which makes protein |
front 16 What are the monomers, main functions, and examples of nucleic acids? | back 16 Nucleotides, are the individual units that constitute DNA and RNA. Each nucleotide is composed of three essential components: a phosphate group, a sugar molecule (deoxyribose for DNA and ribose for RNA), and a nitrogenous base. |
front 17 What is a histogram? | back 17 A graph that shows the frequency of numbers |
front 18 Whats the difference between an endothermic and exothermic reaction? | back 18 Endothermic absorbs energy, exothermic releases energy |
front 19 What is the difference between endothermic and exothermic graphs? | back 19 Exothermic graphs start higher |
front 20 What is hydrolysis? | back 20 The chemical breakdown of a compound due to water |
front 21 What is dehydration synthesis? | back 21 Occurs when two molecules or compounds are joined to form a larger molecule following the removal of water |
front 22 Whats the difference between intermolecular and intramolecular? | back 22 Intramolecular forces are those within the molecule that keep the molecule together, for example, the bonds between the atoms. Intermolecular forces are the attractions between molecules, which determine many of the physical properties of a substance. |
front 23 What do carbohydrate biomelcules look like? | back 23 Hexagon |
front 24 What do lipid biomolecules look like? | back 24 Tentacle poll |
front 25 What do nucleic acid biomolecules look like? | back 25 Hexagons with ball rectangles sticking out |
front 26 What do protein biomolecules look like? | back 26 Balls |
front 27 What are the main types and uses of light microscopes? | back 27 Bright field, dark field, phase contrast, differential interference, and fluorescent microscopes, to make small structures and samples visible by providing a magnified image of how they interact with visible light |
front 28 What are the main types and uses of electron microscopes? | back 28 TEM, SEM, REM, |
front 29 What is endosymbiosis? | back 29 When a large cell would absorb a smaller cell like a mitochondria or chlorplast then combine with it. |
front 30 What are the differences between simple and facilitated diffusion? | back 30 In simple diffusion, molecules move without the assistance of membrane proteins, whereas in facilitated diffusion, membrane proteins assist molecules in their movement downward |
front 31 Why does our plasma membrane form into a bilayer structure? | back 31 Because their fatty acid tails are poorly soluble in water, phospholipids spontaneously form bilayers in aqueous solutions, with the hydrophobic tails buried in the interior of the membrane and the polar head groups exposed on both sides, in contact with water |
front 32 What is a meniscus? | back 32 A meniscus is a curve in the surface of a molecular substance (water, of course) when it touches another material |
front 33 What is the difference between hypo and hypertonic? | back 33 A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane. If a cell is placed in a hypotonic solution, there will be a net flow of water into the cell, and the cell will gain volume. |
front 34 What type of fatty acid is solid at room temperature? | back 34 Saturated fats |
front 35 What do bacteria do to overcome adversity? | back 35 They spore |
front 36 True or false: Conjugation is a form of reproduction | back 36 True: It is a form of sexual reproduction between bacteria |
front 37 True or false: All carbohydrates are soluble in water | back 37 True |
front 38 What are isotopes? | back 38 Isotopes are elements that have different numbers of neutrons but the same number of protons |
