Test Review Chapter 1 Biology

Scientific Method What is the sequence after the problem has been stated? Careful observations Statement of IF….Then Hypothesis Creating Experiment Test hypothesis Collect and organize data Draw conclusions Possibly revise hypothesis and retest

Hypotheses How are they formed? Prior knowledge Logical inferences Imaginative guesses

Controlled Experiment Know it is to isolate and test a single variable.

Theory Well tested explanation using a broad range of observations.

Living Characteristics Growth Use of energy Reproduction Basic unit(s) called a cell Genetic blueprint Homeostasis Evolve Respond to environment

Biology Bio- Life logy- Study of The STUDY OF LIFE: ; The Study of Living things

Homeostasis Process of maintaining a stable internal environment conditions. Regulating body temperature for example by sweating in the heat.
