7 essential functions of life - Correct Answer-order, sensitivity to stimuli, reproduction, adaption, growth and development, regulation, homeostasis. organization of life - Correct Answer-organelles, cells, tissues, organs, organ systems, organisms, populations, community, ecosystem, biosphere phylogenic tree - Correct Answer-a diagram showing the evolutionary relationships among biological species based on similarities and differences in genetic or physical traits or both carl linnaeus - Correct Answer-hierarchical taxonomy: species, genus, family, order, class, phylum, kingdom, domain Eukarya, Archaea, and Bacteria - Correct Answer-The three domains of life, eukarya: organisms that have cells with nuclei (plants, animals, fungi) archaea: single celled organisms without nuclei that are extremophiles living in harsh environments. bacteria: single celled organisms without nuclei inductive reasoning - Correct Answer-from a number of observations, a general conclusion/premise is drawn deductive reasoning - Correct Answer-from a general premise, results are predicted genome - Correct Answer-a cells complete compliment of DNA somatic cells - Correct Answer-human body cells, with 46 chromosomes (23 from mom, and 23 from dad) homologous chromosomes - Correct Answer-the same length, have genes for the same trait in the same location as the other in the pair (the location is called the locus) diploid cell - Correct Answer-somatic cells that have a full set of chromosome pairs (2n) haploid cell - Correct Answer-sex cells (gametes) with only one chromosomes from each pair (23) (n) mitosis - Correct Answer-cell replication, produces two diploid cells meiosis - Correct Answer-creates four haploid sex cells

1st law of thermodynamics - Correct Answer-the total amount of energy in the universe is constant and conserved 2nd law of thermodynamics - Correct Answer-all energy transfers and transformations are never competely efficient heat energy - Correct Answer-energy transferred from one system to another that is not work entropy - Correct Answer-the measure of randomness or disorder within a system (high entropy = high disorder, low energy) kinetic energy - Correct Answer-associated with objects in motion eukaryotic and prokaryotic cells both have - Correct Answer-a plasma membrane binary fission - Correct Answer-asexual reproduction of bacteria the difference between eating a marshmallow and burning a marshmallow is - Correct Answer-how fast and efficiently the energy is converted autotrophs - Correct Answer-an organism that can produce its own food heterotrophs - Correct Answer-organisms incapable of photosynthesis, must consume other organisms photosynthesis would occur faster in a plant with green leaves if it is exposed to what color light - Correct Answer-blue light photosynthesis occurs in the - Correct Answer-mesophyll, in chloroplasts, which is full of stroma and thylakoids calvin cycle - Correct Answer-light independent reaction that takes place in the stroma and is the assembly of sugar molecules and the capture of carbon dioxide, turn ATP back into ADP to be converted again by the sun in eukaryotes, which event leads to a diploid cell - Correct Answer-fertilization enzyme - Correct Answer-catalyzes a specific cellular reaction, has a specific shape which indicates the type of reaction it catalyzes, and is a protein made of amino acids cellular respiration - Correct Answer-is the process by which mitochondria breaks down food molecules to produce ATP entropy - Correct Answer-means that more than 70% of of usable energy is lost going up the food chain

wavelength and energy - Correct Answer-longer wavelength, less energy (infer-red) shorter wavelength, more energy (ultra-violet) how do desert plants balance the need for CO2 with the need to avoid water loss in hot temperatures? - Correct Answer-to conserve water, they close stomata during the way when it is hottest. the plant collects CO2 at night and stores it for the daytime to complete photosynthesis why do plants look green? - Correct Answer-because of the chlorophyll reflects green, but when chlorophyll is reabsorbed, leaves turn yellow and red in the fall to make an image better on the microscope... - Correct Answer-adjust the fine focus, course focus, and ocular lens (10x) and objective lens (80x or 40x, etc) bright field vs. dark field vs. phase contrast - Correct Answer-bright field shows dark specimens on a bright field, dark field shows light specimens on a dark field, and phase contrast is used in clear, unstained specimens
