BIOL 1406 Final (Lone Star) questions
well answered
properties of life - correct answer ✔✔ Cellular organization, homeostasis, metabolism,
responsiveness, reproduction, heredity, growth
nutrient cycle - correct answer ✔✔ the movement and exchange of organic and inorganic mater
back into the production of living matter. the process is regulated by food web pathways that
decompose matter into mineral nutrients
producers - correct answer ✔✔ autotrophic that is they manufacture their own food by the
process of photosynthesis
consumers - correct answer ✔✔ feed on the producers
classification of the environment - correct answer ✔✔ biosphere, ecosystems, communities,
populations, organisms, organs and organ systems, tissues, cells, organelles, atoms
prokaryotic cell - correct answer ✔✔ simpler cell, usually smaller, and does not have
membrane-enclosed organelles (Bacteria and Archaea domains)
eukaryotic cell - correct answer ✔✔ more complex cell, larger, has membrane-bound organelles
- like a nucleus (Eukarya domain- Plantae kingdom, animalia kingdom, fungi kingdom, and
protista)
natural selection - correct answer ✔✔ the gradual process by which heritable biological traits
become either more or less common in a population as a function of the effect of inherited
, traits on the differential reproductive success of organisms interacting with their environment. It
is a key mechanism of evolution
process of science - correct answer ✔✔ observation, question, hypothesis, prediction,
experiment, results
discovery based science - correct answer ✔✔ results that have been found from actually having
carried out the experiment or investigation
hypothesis based science - correct answer ✔✔ an educated guess by a scientist of what will
happen during an experiment or investigation
element - correct answer ✔✔ each of more than 100 substances that cannot be chemically
interconverted or broken down into simpler substances and are primary constituents of matter
most common elements in the body - correct answer ✔✔ oxygen, carbon, hydrogen, nitrogen
subatomic particle - correct answer ✔✔ a particle smaller than an atom
ion - correct answer ✔✔ an atom with a net electric charge due to the loss or gain of one or
more electrons
isotope - correct answer ✔✔ each of two or more forms of the same element that contain
equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in
relative atomic mass but not in chemical properties
electron shells - correct answer ✔✔ the outside part of an atom around the atomic nucleus.
first shell holds up to 2 electrons, after that the shells can hold up to 8 electrons
