Montgomery College BIO 150 Lecture
Test 1 - Chs. 1-5, 8.4-8.5 Study Guide
Solutions
living organisms have cells, movement, reproduction and growth abilities. -
ANSWER✔✔-compare living organisms with nonliving objects.
viruses have DNA. however, they are not made of cells and cannot extract energy from
the environment. - ANSWER✔✔-explain why viruses are difficult to classify as living or
nonliving.
1. biosphere, 2. ecosystems, 3. communities, 4. populations, 5. organisms, 6.
organs/organ systems, 7. tissues, 8. cells, 9. organelles, 10. molecules - ANSWER✔✔-
outline the major levels of biological organization.
novel properties emerge that are absent from the preceding level. example:
photosynthesis occurs in organized chloroplast but not in a tube of everything in a
chloroplast separated - ANSWER✔✔-discuss the meaning of the phrase 'emergent
properties.' give an example.

,there is unity in the kinship among species that descent from common ancestors. ex: the
extremely different types of eukaryotes still have the same cilia - ANSWER✔✔-discuss
the unity that underlies the diversity of life. give an example.
from conclusions about individuals varying from traits, populations producing more
offspring than their next generation, and species adapting to environments, Darwin
decided that the environment selecting te best to survive was evolution's mechanism for
descent with modification. - ANSWER✔✔-outline Charles Darwin's theory of evolution
by natural selection. include the phrase 'descent with modification.'
1. make observation, 2. ask question, 3. formulate hypothesis, 4. design experiments to
test hypothesis - ANSWER✔✔-outline the steps of the scientific method.
it is the study of the natural and physical world; supernatural and religious questions
are outside the bounds of science - ANSWER✔✔-discuss the limits of science.
is there a God? - ANSWER✔✔-give examples of questions that cannot be answered by
science.
the scientific study of life. - ANSWER✔✔-define: biology
the new properties that arise with each step upward in the hierarchy of life, owing to
the arrangement and interactions of parts as complexity increases. - ANSWER✔✔-
define: emergent properties

, descent with modification; the idea that living species are descendants of ancestral
species that were different from the present-day ones; also defined more narrowly as
the change in the genetic composition of a population from generation to generation. -
ANSWER✔✔-define: evolution
the steady-state physiological condition of the body. - ANSWER✔✔-define: homeostasis
dependent: a variable whose value is measured during an experiment to see if it is
influenced by changes in the independent variable.
independent: a variable whose value is controlled and manually changed during an
experiment to reveal effects on the dependent. - ANSWER✔✔-define: dependent vs.
independent variables
qualitative: categorical measurement expressed by means of a natural language
description.
quantitative: information that can be measured and written down with numbers -
ANSWER✔✔-define: qualitative vs. quantitative data
a testable explanation for a set of observations based on the available data and guided
by inductive reasoning. a hypothesis is narrower in scope than a theory. - ANSWER✔✔-
define: hypothesis
an explanation that is broader in scope than a hypothesis, generates new hypotheses,
and is supported by a large body of evidence. - ANSWER✔✔-define: theory
