Humber Admissions Test practice Questions and Answers with complete solution

Activation energy - Energy needed to get a reaction started Active transport - The movement of materials through a cell membrane using energy; from a low concentration to a high concentration until it reaches disequilibrium. Adenine - The base that pairs with Thymine in DNA, and Uracil in RNA Aerobic cycle - Glycolysis -> Kreb's cycle -> ETC Aerobic respiration - Cellular respiration that requires oxygen Allele - Different forms of a gene Anaphase - Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell anerobic respiration/fermentation - Cellular respiration that does not require oxygen Anions + anions / Cations + cations - These ions repel each other Anions + Cations - These ions attract each other Anions are - negatively charged ions Artificial selection - Selection by humans for breeding of useful traits from the natural variation among different organisms (ie. dog breeds)Atomic number - the number of protons in the nucleus of an atom Atomic size trend - increases from top to bottom within a group; decreases from left to right in a period Atoms - Basic unit of matter Aufbau Principle - the rule that electrons occupy the orbitals of lowest energy first Avogadro's Law - A principle that describes the direct relationship between volume and the number of moles; temperature and volume remain constant Bohr Model - A model resembling planets revolving around the sun in orbits, useful in visualizing the structure of atoms. Boyle's Law - A principle that describes the inverse relationship between the pressure and volume of gas; temperature remains constant Bulk transport - Moves large molecules and particles across plasma membrane through means called phagocytosis or pinocytosis Carbohydrates - Connected to the protein found in the cell membrane, they help with cell communication Cations are - positively charged ions Cellular reproduction - cell division Cellular respiration - The process by which cells use oxygen to produce energy from foodCelsius to Kelvin - K=C+273 Centrioles - Cell organelle that aids in cell division in animal cells only Charles' Law - A principle that describes the direct relationship relationship between the temperature and volume of a gas; pressure remains constant Cholesterol - Provides strength and fluidity to the cell membrane Cilia - Hairlike projections that extend from the plasma membrane and are used for locomotion Codominance - A condition in which both alleles for a gene are fully expressed combination reaction - a chemical change in which two or more substances react to form a single new substance combustion reaction - a chemical reaction that occurs when a substance reacts with oxygen, releasing energy in the form of heat and light
