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.

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)

large molecules of carbohydrates, proteins, lipids

up by the ER
k. vacuole- storage for food, water, and proteins, (rarely for wastes) (all plants
and some animals have them- plants have a large central vacuole)

to middle and end of cells; one pair per cell
m. cell membrane- thin layer of lipid and protein separating cells contents from
outside environment

Mitosis: must be able to recognize diagrams!
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

sides

daughter cells (in plants cell plate forms between two
daughter cells)

C matches with G, and T matches with A)
86. 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

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
