Analyzing Populations
The number of individuals divided by the space they occupy.
What is population density?
Examples of these are a thermostat and the regulation of blood sugar, insulin, and glucagon.
What are feedback loops?
Clearly defining the problem to be solved is the first step in this process.
What is the engineering design process?
These are the negatively charged particles in an atom.
What is an electron?
This molecule stores energy for cellular processes.
What is ATP?
This is represented by the point at the top of the logarithmic growth curve when growth slows down.
What is carrying capacity?
In 1988 several large forest fires occurred in Yellowstone National Park. This process occurred after these fires.
What is secondary succession.
This is the application of scientific knowledge for practical purposes.
What is technology?
ATP (adenosine triphosphate) stores energy in the bonds between these groups.
What are phosphate groups?
these are the two products of the Kreb's cycle.
What are ATP and Carbon Dioxide?
Examples of this kind of limiting factor are parasites, food shortages, and decreases in prey.
What is Density-dependent limiting factors?
Water in the soil enters the roots of a plant. The matter in this system has moved from this sphere to the biosphere.
What is the hydrosphere?
Scientists are developing an artificial knee. If the new artificial knee is heavier than previous artificial knees to improve its lifespan, it would be considered this.
What is a tradeoff?
Light-independent reactions do not need light, but they do need this compound.
What is Carbon Dioxide?
A cell that requires a lot of energy might contain large numbers of these structures.
What are mitochondria?
The movement of a single caribou into a herd.
What is immigration?
a community of organisms that develops in a previously populated area after a disaster such as a fire.
What is a climax community?
Scientists use these to test how the process will work under different conditions.
What are models?
This is what atoms connected with covalent bonds share.
What are pairs of electrons?
This element picks up electrons at the end of the electron transport chain.
What is Oxygen?
Bobcats are generally solitary and establish territories of a certain size where they hunt for food. Scientists expect Bobcats to have this type of population dispersion.
What is uniform dispersion?
This is the most important factor in an ecosystem's resilience.
What is biodiversity?
Charlotte made a flow chart to illustrate the process of ATP production in bacteria. Her chart is an example of this kind of model.
What is a conceptual model?
These two compounds are the products of photosynthesis and the reactants of cellular respiration.
What are Oxygen and glucose?
During this process a 4-carbon molecule is recycled, Pyruvate is broken down into a 2-carbon molecule and carbon dioxide, and Citric acid is broken down, creating carbon dioxide as a waste product.
What is the Kreb's cycle?
