biology
Phosphorus is accessed by organisms only in this way.
What is…by absorption from the soil?
4 kingdoms that contain eukaryotic organsms.
What are “protista”, fungi, plantae, and animalia?
The naming system that identifies a domestic cat as Felis catus.
What is binomial nomenclature?
The name is formed from the genus and species.
The reason for various weather patterns around the globe.
What is the uneven heating of the earth by the sun? Rising and cooling air cause areas of high pressure (prevents rainfall) and low pressure (produces rainfall).
What is biomass and how does it change as you move up an energy pyramid?
Biomass is the mass of organisms by amount of tissue. As you move up an energy pyramid, there are less organisms and therefore less biomass.
The name of the evolutionary pattern where organisms evolve rapidly and then have periods of very little change.
What is punctuated equilibrium?
The levels of organization in order from least similar to most similar.
Kingdom, phylum, class, order, family, genus, species
The process by which atmospheric nitrogen becomes usable in the soil.
What is nitrogen fixation?
Describe the quick carbon cycle.
The quick cycle happens when autotrophs absorb carbon from the air through photosynthesis and organisms release it through respiration.
A characteristic that shows a common ancestor by similar anatomical structure.
What are homologous structures?
Explain the endosymbiotic theory.
Bacteria entered prokaryotic cells to become mitochondria and chloroplasts.
List all 9 of the world’s terrestrial biomes.
•Tundra
•Taiga
•Grasslands
•Deciduous Forest
•Savanna
•Chaparral
•Rainforest
•Desert
•Alpine
Density-dependent and density-independent factors are different in this way.
Density-dependent factors are usually biotic and have an increasing effect as population increases. Density-independent factors are usually abiotic and affect all populations, no matter their size.
3 of the 5 conditions required for genetic equilibrium.
No mutations
No immigration/emigration (gene flow)
No natural selection
Random mating (no purposeful selection of partners)
A large population
Iron-59 has a half life of 45 days. 30 g of this isotope is used for a medical test. The amount of iron-59 left after 90 days would be…
What is 7.5 grams?
The two factors included in the calculation of an ecological footprint.
What are…the resources consumed and the waste produced?
The science of classifying organisms.
taxonomy
The 4 types of isolation that can cause speciation.
What are geographical isolation, mechanical isolation, temporal isolation, and behavioral isolation?
Describe how each type of fossil is made: mold, cast, trace, preserved body part.
Mold (imprint in rock shaped like an organism)
Cast (mold filled with minerals that creates a model)
Trace (fossils of tracks, feces, tooth marks that show an organism’s behavior)
Preserved body part (organisms or parts of organisms fully preserved in tree sap, tar or ice)
The main difference between primary and secondary succession.
What is the existence of soil?
No soil= primary; soil exists= secondary
