Term
Rene` Descartes
Definition
FOUR PRECEPTS TO SCIENTIFIC THOUGHT
1.Avoid predjudice and doubt the truth
2. Divide problem into manageable parts
3.Construct solution in ascending order of simplicity.
4.Review to assure completeness and avoid omission.
Term
Albert Einstein
Definition
Theory of relativity referred to the black box which refers to electromagnetic fields.
Term
controlled variable
Definition
The variable in an experiment we do not want to change, scientist wants these to remain constant throughout experiment for accuracy and fairness.
Term
independent variable
Definition
the variable that is changed by the scientist to conduct the experiment
Term
variable
Definition
things that can change or be changed in an experiment
Term
dependent variable
Definition
the variable or change the scientist observes, it is the response from change in the independent variable
Term
Francesco Redi
Definition
disproved spontaneous generation theory.
The decayed flesh and flies in a jar experiment.. trying to prove that maggots were not produced by decaying flesh.
Term
Spontaneous generation
Definition
The thought that living things come from nothing/non living matter
Term
Ordered biological structure
Definition
DNA or RNA structures and characteristics
Term
Energy utilization or Metabolism
Definition
All the chemical processes that take place in the body. Take in energy and use it to perform many kinds of work.
Term
Regulation or Homeostasis
Definition
Temperature- All organisms maintain relatively constant internal conditions that differ from their environment
Term
REPRODUCTION
Definition
Fundamental process of all life. Biological process to produce offspring.
Term
BIOGENESIS
Definition
USUALLY REFERS TO VIRUSES

Process in which life forms arise from similar life forms.
Term
EVOLUTIONARY ADAPTATION
Definition
organisms interact with other organisms and non living things in ways that influence their survival, overtime populations evolve adaptations to their environment for survival.
Term

4.ORGANISM (everything put together, can be single or multi cellular,any living system or living thing)
Term
Organization of Life
**POPULATIONAL LEVEL**
Definition
1.Species (group of organisms similar in appearance that are capable of breeding and producing FERTILE offspring)

2. Populations (group of same SPECIES of same geographic area)

3. Community (group of POPULATIONS in same geographic area)

4. Ecosystem (group of organisms and its non living environment)
