Biology - ANSWER✔✔ You Is the study of the science of life.
It's not just facts and theories. It is also a process. Modem science, including

to the Scientific Method
General methods of critical thinking: Deductive Reasoning - ANSWER✔✔

General methods of critical thinking: Inductive Reasoning - ANSWER✔✔
Reasoning from a series of specific facts or observations to a general principle.
Scientific Method - ANSWER✔✔ a) Observation -- careful reporting of actual
events in the biosphere.
b) Hypothesis -- a TENTATIVE (Subject to change) explanation formulated from
the
observations using inductive reasoning. It attempts to explain the event and is
subject to tests.
c) Experimentation - carefully designed lab work or field work to test the
hypothesis using deductive reasoning. An experiment must consist of an
experimental group and a control group for comparison purposes.
d) conclusion -data from experimentation should either support or contradict the
hypothesis. If a hypothesis is supported by repeated experimental testing, it is now
qualified as a Theory. [If the data contradict the hypothesis, a new hypothesis and
new experimentation work will have to be done].
,Theory - ANSWER✔✔ Is a unifying explanation for a broad range of
observation. Although (THEORIES ARE NOT ABSOLUTE FACTS) in science,
they serve as the solid foundation in the understanding of
natural phenomena.
The Experimental Method - ANSWER✔✔ • Experiments are situations
designed to test a specific hypothesis
• Scientists can manipulate the environment, one variable at a time.
• This helps the scientist to determine what specific variable is involved
(controlled and experimental groups)

continuum of heredity in their species.
, 5 basic properties found in all living things; Heredity - ANSWER✔✔ all living
organisms possess a genetic system
using deoxyribonucleic acid (DNA) to transmit their characteristics from parent to
offspring.

3. Evolution
4. Cooperation
5. Structure determines function ("form fits function"):
6. Homeostasis

function and interact with each other at many levels.
B) Each living organism is composed of :
particles, atoms, molecules, macromolecules
organelles, cells, tissues, organs, organ systems.
C) Among different living organisms, there is another HIERARCHY of
complexity: species population community ecosystem biomes biosphere
Biosphere - ANSWER✔✔ All life on Earth and the nonliving portion of Earth that
support life.
Ecosystem - ANSWER✔✔ A community together with its nonliving surroundings
