What is the ability for an organism to maintain a stable level of internal conditions?
What is homeostasis?
100
What is the basic structure of an atom, what are the charges of these particles, and where are each found?
What is a proton (+) and neutron (0) are in the nucleus, and the electrons (-) are found orbiting the nucleus.
100
What accounts for water's polarity?
What is water is a bent molecule that causes partial positive and negative areas.
100
What is ecology?
What is the study of the interactions between organisms and the living and nonliving components of their environment?
100
What factor accounts for the climate change due to switching wind patterns along the equator?
What is El Niño?
200
What type of organism obtain their energy by making their own food?
What is an autotroph?
200
What type of bond shares its electrons? What type of bond gives up its electrons?
What is a covalent bond and what is a ionic bond?
200
What are two affects that having a bent structure do to water?
What is adhesion (water's ability to attract to unlike substances), and cohesion (water's ability to attract to itself).
200
What are the 5 levels of organization in ecology?
What is biosphere, ecosystem, community, population, and organism?
200
What has accounted for a major decrease in the ozone layer?
What is CFCs?
300
What are the six characteristics of life?
What is all things are composed of cells, all living things are highly organized (both molecular and cellular level), all living things use energy, all living things maintain stable internal conditions, all living things grow, and all living things reproduce?
300
How can we lower the activation energy for a reaction? What if it is in a living organism?
What is using an catalyst? What is an enzyme?
300
What is a functional group and give an example?
What is a group of molecules attached to a larger molecule that influence the properties of the entire molecule. A hydroxyl group influences a compound to be an alcohol.
300
What is the difference between an abiotic and biotic factor? Give an example of each.
What is an abiotic is a non-living component such as oxygen or water and a biotic factor is a living component such as an organism.
300
What refers to the variety of organisms in a given area?
What is biodiversity?
400
A controlled experiment is
What is an experiment that compares a control group with an experimental group. What is usually involves is an independent variable and a dependent variable.
400
What is an aqueous solution and how do we form one?
What is a solution formed by dissolving a solute in a solvent that is water?
400
What is the difference between a condensation reaction and hydrolysis?
What is a condensation reaction attaches monomers together to form polymer by removing a water molecule and hydrolysis breaks a polymer into monomers using a water molecule break the bonds.
400
What is the difference between density dependent and density independent factors and what are examples of each?
What is density-independent factors such as weather reduce the population regardless of the population size. Density dependent factors such as food or nesting sites effect the population based on the size of the population.
400
What is responsible for the warming of Earth?
What is rise in carbon dioxide in the upper atmosphere not allowing heat to escape.
500
The difference between a light microscope and an electron microscope is
What is a light microscope can only see 2-D images since the specimen has to be sliced very thin to allow light to go through it. An electron microscope also one to see a 3D image by bouncing electrons off the specimen.
500
How do hydroxide and hydronium ions affect a solution (pH)?
What is the pH level changes. If the hydroxide ions are higher than the solution has a pH of 8 or higher, if the hydronium ions are higher than the solution has a pH of 6 or lower.
500
What are the four main classes of organic compounds?
What is carbohydrates, lipids, proteins, and nucleic acids?
500
What are the 5 symbioses and how do they differ from one another?
What is predation, parasitism, competition, mutualism, and commensalism?
