Basic Biology And Scientific Method Flashcards
Independent variables
Factor you can manipulate
The steps of the scientific method and definition
PHEOC
Problem-identify through observation
Hypothesis-proposed solution or educated guess to problem
Experimentation-test the hypothesis through experiments
Outcome-collect data
Conclusion-draw conclusion based on outcome
Repeat experiment
Dependent variable
Factor that responds to the change and can be measured
Control group
Does not contain any variables
Factors remain unchanged
Experimental groups
Contains variables that are being tested
Covalent bonds
Bonds in which electrons are shared
Ionic bond
Bonds in which electrons are either gained or lost
Asexual reproduction
Reproduction involving only one parent
Sexual reproduction
Reproduction which involves two parents
DNA
The molecule in which the hereditary info is stored
Unicellular
Consists of only one cell
Multicellular
Consists of multiple cells
Characteristics of life
Reproduction-give offspring
Cells-all living things made out of cells
Homeostasis-maintain a stable internal environment
Growth and development-grow and develop overtime
Genes-contain universal genetic code
Adaptation-can change to be accustom to environmental changes
Evolution-change in species over generations
Energy-use or obtain energy
Homeostasis
Organisms maintain balance with the internal and external environments
