What is a cell? Smallest unit of life that can live and reproduce.
All living things are made up of these cells
What are the steps of the scientific method? Observe, Question, Hypothesis, Prediction, Experiment, Results/Data
How are hypothesis and predictions related? A hypothesis can lead to many different predictions
Inductive Reasoning General statements about a series of observations. Statement ties observations into a them or general rule...Ex] all school walls are beige.
Deductive Reasoning Used in making predictions in experiments. Uses general principle to predict an expected observation.
What are the 3 domains? Bacteria, Archea bacteria, and Eukaryotes
Single-celled, no nuclues, most ancient of all domains Bacteria
Single-celled but closer to eukaryotes Archea bacteria
Contains a nucleus and can be single celled or multi-celled Eukarya
Can do things no other living thing can do. Ex] produce methane, break down wood. Bacteria
(Extreme-ophiles) Live in extreme conditions. Ex] Yellowstone hot pools and frozen solid ice caps. Used in fingerprint DNA Archae
Protista grow into huge kelp in the water. Plants don't grow in salt water. They are? Eukaryote
What are the 6 kingdoms? Protistants, Plants, Fungi, Animals, Eukaryotes, Archaebacteria, and eubacteria
Decomposers that break down dead things and don't use photosynthesis Fungi
Change in structure of DNA. Basis for the variation in heritable traits. Mutation
What are the levels of Organization? Cell, multi-celled organism, population, community, ecosystem, biosphere
What are the levels of taxonomic classification? Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
What makes something alive? cellular organization, order, sensitivity, growth, energy, reproduction, homeostasis, and evolution
All living things are made up of these molecules: Nucleic Acid, proteins, carbohydrates, and lipids
A trait that gives one an advantage in survival or reproduction Adaptive trait
Genetically based change in a line of descent. Populations change, not individuals Evolution
Individuals with the most desirable traits are selected for breeding. Artificial Selection
Heritable traits vary but some are more adaptive than others. This is when the adaptive trait becomes dominant in a species over time. Natural Selection
