Biology 1320 Midterm - UPEI Kemp Study
Guide with Complete Solutions
prokaryote - Answer✔️✔️-a single celled organism that has neither a distinct
nucleus with a membrane or other specialized organelles. prokaryotes
include bacteria and cyanobacteria
eukaryotes - Answer✔️✔️-an organism consisting of a cell or cells in which
the genetic material is DNA in the form of chromosomes contained within
a distinct nucleus. Eukaryotes include all living organisms except
eubacteria and archaebacteria
archaebacteria - Answer✔️✔️-microorganisms that are similar to bacteria in
size and simplicity of structure, but radically different in molecular
organization. now believed to constitute an ancient intermediate group
between the bacteria and eukaryotes
eubacteria - Answer✔️✔️-a bacterium of a large group typically having
simple cells with rigid cell walls, and often flagella for movement. the
group comprises of the "true" bacteria and cyanobacteria, as distinct from
archaebacteria. found mainly in intestines of vertebrates and in soil.
Mycoplasms - Answer✔️✔️-any group of small parasitic bacteria that lack
cell walls and sometimes cause disease
hierarchy - Answer✔️✔️-any system of persons or things ranked one above
the other; groups in groups

hierarchical structure - Answer✔️✔️-groups nested within groups
hypothesis - Answer✔️✔️-Science: an explanation that can be tested and
falsified
non-science: an assumption or guess
speculation - Answer✔️✔️-conclusion based on thinking about a subject. in
science, we frame a question, test it, and are ready to abandon it.
theory - Answer✔️✔️-science: broad explanation supported by a huge body
of evidence

non-science: speculation
evolution - Answer✔️✔️-the change in genetic composition of a population
over time
earth and solar system originated... - Answer✔️✔️-~4.6 b.y.a.
early earth conditions (atmosphere and water temp, presence of organisms)
- Answer✔️✔️-atmosphere: water vapour, volcanic gases, methane, CO2,
H2S, N2
water temp: very hot - 40-60˚C
Lab experts produced organic molecules that eventually formed
reproducing molecules in these types of conditions... therefore we
speculate that organic molecules formed, eventually forming reproducing
molecules
fossils - Answer✔️✔️--evidence of past life
-most in sedimentary rock
-older fossils are in older rock layers
-position says one is older than other
dating fossils - radiometric dating - Answer✔️✔️-based on decay time for
radioactive isotopes
origin of earth - clock analogy - Answer✔️✔️-1. origin of earth and solar
system ~4.6 b.y.a
