BIL 150 STUDY GUIDE TEST PAPER
QUESTIONS WITH THOROUGH ANSWER
EXPLANATIONS
●● hypothetico-deductive method
Answer: good science. idealized version of science
●● symbiosis
Answer: a relationship when individuals of two or more species live in
direct and intimate contact with one another. this relationship can change
based on conditions and circumstances
●● mutualism
Answer: type of symbiosis (+,+)
●● commensalism
Answer: type of symbiosis (+,0) (0=no effect)
●● parasitism
Answer: type of symbiosis (+,-)
●● hypothesis
,Answer: causal explanation for an event and used for further
observations and experiments
●● theory
Answer: explanation that is broad scope and supported by a large group
of evidence
●● law
Answer: generalization that scientists have observed for a long time and
never deviated
(only example in biology is mendals law of independent assortment)
●● bad science example
Answer: measles, mumps, rubella vaccine is linked to autism
WHY
-no control group
-small sample size
-$ from anti-vaccine organizations
●● ugly science example
Answer: Nazi Germany
,●● Characteristics of Living Systems
Answer: 1. order
2. reproduction
3. response to environment
4. evolutionary adaption
5. energy utilization
6. homeostasis (internal regulation)
7. growth and development
●● levels of biological organization
Answer: molecule/organelle/cell/tissue/organ/organ
system/organism/population/community/ecosystem/biosphere
●● what level of biological organization do we know most about
Answer: the lower levels
●● molecule
Answer: a particle composed of one or more atoms held together by a
chemical bond. smallest particle of a compound that displays all the
properties of that compound
●● cell
, Answer: the basic unit of life, consisting of outer cell membrane
surrounding cytoplasma and genetic material
●● tissue
Answer: a group of usually small cells that together carry out a specific
function
●● organ
Answer: a structure of an organism (e.g, intestines), usually composed of
several tissue types-organized into a functional unit
●● organ-system
Answer: two or more organs working together in execution of a bodily
function (the digestive track)
●● population
Answer: a group of individuals of the same species, found in the same
time and place, and actually or potentially interbreeding
●● community
Answer: two or more populations of different species living and
interacting in the same area
●● ecosystem
