What are the steps to the scientific method?
What are: Problem (or Observation) Question Hypothesis Experiment (including collecting data) Analyzing Data Conclusion
100
What are the characteristics of living things?
Made of Cells, Reproduce, Respond to Environment, Obtain and Use Energy, Grow and Develop, Adapt to Environment
100
Define "Natural Selection". What are the steps (what is required) for Natural Selection?
Survival of the fittest. Organisms which are best adapted to their environment are more likely to survive and pass on their genetic information (producing offspring who can compete and survive).
100
What happens to energy as it is moving through a food chain? How does this impact the number of trophic levels in an energy pyramid?
Energy decreases. Because energy decreases, there usually aren't consumers higher up in the food chain than the tertiary level.
100
Compare and contrast heterotrophs with autotrophs:
Autotrophs make their own food (obtain their energy on their own, from the sun). Heterotrophs need to eat other organisms to obtain energy and nutrients.
200
What is an independent variable? What is a dependent variable? What is a control variable?
Independent: The variable a scientist manipulates or changes in an experiment. Dependent: The responding variable, which is affected by the independent variable. Typically, what the scientist is measuring.
200
Name the classification of organisms, from the most general to the most specific?
Kingdom, Phylum, Class, Order, Family, Genus, Species
200
What is a homologous structure? What is an analogous structure?
Homologous structures are similar in structure and function and indicate a recent common ancestor between two organisms. Analogous structures may be somewhat similar in structure and function but do not indicate a common or recent ancestor.
200
Other than Natural Selection, what are some other modes of evolution?
What are: geographic isolation, reproductive isolation.. Any more?
200
How is Carbon removed from the abiotic portion of the environment? How is it returned?
Carbon is removed through the process of photosynthesis, and returned to the abiotic portion (atmosphere) through cellular respiration, burning fossil fuels, and burning forests.
300
Compare and contrast a control group with an experimental group:
An experimental group receives the independent variable while the control group does not receive the independent variable.
300
Compare and contrast a prokaryotic cell with a eukaryotic cell:
Both cells. Eukaryote: Membrane bound organelles, Nucleus Prokaryote: Unbound nucleoid, no membrane bound organelles, cell wall Anything else?...
300
What is some of the evidence which supports the theory of evolution?
What are: Fossils, Similarities Between Related Living Organisms, DNA Testing, Bacterial Resistance to Antibiotics
300
Compare the movement of matter through an ecosystem with the movement of energy:
Matter cycles through an ecosystem (carbon, nitrogen, phosphorous, water) while energy moves through an ecosystem and is not cycled.
300
What are some of the levels of biological organization we discussed in class?
What are: biosphere, ecosystem, population, community, organism, cell, atom..

A scientific study showed that the depth at which algae were found in a lake varied from day to day. On very clear days, the algae were found as much as 6 meters below the surface of the water; however, the algae were only 1 meter below the surface on the cloudy days. What are the independent and dependent variables in the scenario above?
Independent Variable: Type of Day (sunny or cloudy) Dependent Variable: Depth at which algae were found in a lake

Draw a food chain with one producer and 3 consumers.
Food chains will vary
400
In an imaginary food chain, if the producers can obtain 5,000KCal from the sun, how much energy is available to the secondary consumer?
What is 50 KCal

Mr. Ohl was trying to increase the fuel efficiency of his car and decided to follow the steps of the scientific method to see if the type of gas he purchased affected his miles per gallon (m.p.g.). He bought gas for one week from Speedway, a second week he purchased gas from B.P. and the third week he purchased gas from Quality Dairy. He only drove to and from work and to the market on the weekends. Identify the following from the experiment: Questions, Controls, Independent Variable, Dependent Variable
Question: Which type of gas gets the best m.p.g.? Controls: How long the car is driven (1 week) Independent Variable: Where the gas is purchased Dependent Variable: M.P.G.

"Felis catus" is the Latin name for the cute, domestic house cat. This is an example of "binomial nomenclature". Is the species or genus capitalized?
What is the Genus.
