. What would you like to do?
A repeated tested, large scientific idea that ties together information from several different sources
A tentative explanation about a phenomenon
Scientific idea that ties together information from several different sources
The Theory of Evolution
States that all organisms descend from a single, common ancestor
The evolutionary history of a group of species
What could you use to determine relationships between organisms
How many RNA nucleotide bases code for an amino acid?
3 RNA bases, which all together are called codons
When DNA gets converted to RNA
Trophic Levels (In Order)
- Stops of the ecosystem:
- 1. Primary Producers
- 2. Primary Consumers (Herbivores)
- 3. Secondary Consumers (Carnivores)
- 4. Tertiary Consumers (The "top" Carnivores)
- Man-made substances
- Excessive quantities of natural substances that contaminate the environment
Produce their own energy through photosynthesis
Obtains energy by feeding on other organisms
The process of increasing rates of plant growth and decay due to the addition of excess nutrients into an aquatic system
The use of plants to clean up the environmental pollution
Is carbon dioxide in the atmosphere natural and is it required for beneficial greenhouse effect?
Yes, it is natural to have carbon dioxide in the atmosphere and is required for the beneficial greenhouse effect
A community of biological organisms plus the non living components with which the organisms interact
Excessive amounts of carbon dioxide added to the atmosphere can lead to excess heat being trapped and a rise in the temperature
What is the difference between the ocean dwelling stickleback fish and the pond dwelling stickleback fish?
- Some pond dwellers have no pelvic spine or armor plates
- pond dwellers have shorter dorsal and pelvic spines
Conditions that have to be present for natural selection to occur?
- Various structures in different species having the same appearance, structure, or function but have evolved separately
- Do not share common ancester
Similarities that exist between organisms due to common ancestry
The pelvic spines of the stickleback fish are homologous to ?
the hind limbs of a tetrapod (4 legged organism)
Enzyme that is responsible for transcription
- The process by which one species splits into 2 distinct species
- 2 populations evolve over time as separate entities with physical and behavioral differences
- 2 Types: reproductive isolation & genetic divergence
(Predictor Variable) the factor that is deliberately changed or manipulated
(Response Variable) the factor that changes as result of the changes made in the independent variable
Baseline value for dependent variable
The purpose of what section of a primary source scientific paper is to analyze and interpret the results of your experiment through figures and graphs?
What are the primary sources of info?
Papers written by scientists that describe original research that they have conducted (Scientific Papers)
What section of a scientific paper summarizes the experiment?
Correct order for a scientific paper
abstract. intro. methods. results. discussion. acknowledgements. literature cited
A good hypothesis is?
Testable and falsifiable
Order of the steps for the scientific method?
Observations. Questions. Hypothesis. Prediction. Experiment. Data. Conclusion
Conditions that are the same for all levels of treatment in an experiment
Allows the experiment to account for random variation in test samples
A measure of how much the data deviate (vary) from the mean
