Biology Final Review 1. life 2a. organization and structure (cellular structure and function): need some sort of structure, cells, tissues, organs etc. to carry on life functions b. growth and development: grow and develop from juvenile to adult- need to get and use “food” energy- (metabolism) c. reproduction (heredity): necessary to sustain survival as a species d. response and adaptation (homeostasis, evolution, & interdependence)organisms must respond and adapt to internal and external changes to survive 3. abiogenesis/spontaneous generation 4. Redi- observed flies going in and out of open jars with rotting meat; maggots appeared later; put lid on jar- no maggots appeared; put mesh screen on jars no maggots appeared—previously people believed rotting meat made maggots, garbage made rats etc. Pasteur- control setup: heated (pasteurized) soup broth in flask with curved neck to kill any bacteria; no dust could enter- one year later still no bacteria experimental setup: heated broth in flask with straight neck to kill bacteria; dust could enter- one day later broth was cloudy with bacteria 5. biogenesis 6. state the problem, make a hypothesis, design an experiment, perform experiment and analyze the results, and make a conclusion (accept or reject hypothesis) 7. observation 8. control (setup) 9. variable 10. an idea that one has, through observations, to explain the occurrence of something before experimenting and testing the idea 11. theory 12. liter (L), graduated cylinder 13. gram (g), triple beam balance 14. meter (m), meter stick 15a. proton, positive, in the nucleus b. neutron, neutral, in the nucleus c. electron, negative, outside nucleus in orbits, energy levels, clouds, shells 16. atom 17. compounds 18. electrons give chemical properties (protons and neutrons physical properties), negative ions (atom with a charge) bond with positive ions; gain electrons gives negative charge, lose electrons gives positive charge 19. covalent- sharing electrons, stronger bond; ionic bond (+ and – charge attract, weaker bond 20. in all of these we are assuming there is no net charge so protons and electrons are equal; number of protons determines atomic number so they are equal; (mass = protons + neutrons) or (mass – protons = neutrons) Li: 3, 7, 3, 4, 3 Mn: 25, 55, 25, 30, 25 Mo: 42, 95, 42, 53, 42 Fe: 26, 56, 26, 30, 26 Co: 27, 59, 27, 32, 27 Reactants are chemicals added together to make something or is a compound broken down into individual parts 21.

Prophase: nucleolus and nuclear membrane disappear, chromatin uncoils to chromatid, mitotic spindle forms, centrioles start moving to opposite poles, chromosomes become visible during pro-metaphase Metaphase: spindle fibers attach to centromeres and pull chromosomes to middle (equator) of cell Anaphase: centromeres are pulled apart and chromosomes go to opposite sides Telophase/Cytokinesis: nuclear envelope reforms, chromosomes begin to ball back cleavage furrow deepens and splits into two daughter cells (in plants cell plate forms between two daughter cells) 63. homologous pairs/sister chromatids 64. centromere 65. prophase I, metaphase I, anaphase I, telophase I (cytokinesis I) prophase II, metaphase II, anaphase II, telophase II (cytokinesis II) 66. variation 67. identical, mitosis Remember in meiosis cells start out with double the chromosomes that divide twice (4 daughter cells) to end up with half as many chromosomes in each cell 68. recombinant/recombined/different, meiosis 69. 46 (23 pairs), diploid; 23, haploid 70. sex-linked 71. autosomes 72. linked genes 73. non-disjunction 74. genetic karyotyping/gene mapping 75. human genome project 76. a purine (A & G) with a pyrimidine (C & T) (A & T and C & G) 77. adenine and thymine & cytosine and guanine 78. double helix/ twisted ladder 79. 5 carbon sugar (deoxyribose)- on backbone/sides of ladder phosphate- on backbone/sides of ladder nitrogenous bases- steps on ladder between backbone 80. 1. enzymes break weak hydrogen bonds between the bases and separates/unzips 2. unpaired nucleotides in nucleus pairs up with complimentary bases 3.

UAGCCCUAGUCAGUCAUG 87. mRNA leaves nucleus to go through cytoplasm to ribosomes; tRNA leaves behind an amino acid (codon- group of 3 bases), more and more link together until a stop codon is reached- at this point the amino acid chain sequence stops and a certain protein is made 88.

Thymine, Uracil 95. mutagens 96. the disruption of the DNA sequence in a gene: frameshift mutation: deletion or addition of nucleotides that disrupt codons; gets copied wrong during translation point mutation: a change in only one nucleotide; affects only one codon- one subs for another but gives same amino acid so less disruption 97. a rearrangement in the genes on a chromosome or a whole chromosome deletion: part of a chromosome is lost duplication: part of chromosome is doubled inversion: part of a chromosome breaks off and attaches to the same chromosome in a different order translocation: part of a chromosome (or the whole chromosome) breaks off and attaches to a different chromosome (non-homologous pair) 98. oncogene 99. carcinogen 100. avoid too much sun, avoid carcinogenic chemicals, hope you have good genes
