The organelle of eukaryotic cells that contains the chromosomes and the central part of every cell.
Nucleus

Diffusion
100
Female gametes and Male gametes
Eggs and Sperm

List the organic molecule groups.
Carbohydrates, Proteins, Lipids, and Nucleic Acids.
200
The "powerhouses" of the cell or the organelle in which respiration takes place in eukaryotes.
Mitochondrion
200
Most complex on the levels of organization chart
Ecosystem
200
What typer of process goes from low -> high?
Osmosis
200
Which term has the definition: the transfer of genetic information from one generation to the next?
Heredity

What is the difference between planktonic, benthic, and nekton organisms?
Planktonic- Those that drift in water.
Benthic- Those that live on the bottom.
Nekton- Those that are strong swimmers.
300
An extensive system of folded membranes present in most eukaryotic cells.
Endoplasmic Reticulum
300
Definition of population
A group of organisms belonging to the same species and living in the same place.
300
What are osmoconformers?
An organism that allows its internal salt concentration to change with the salinity of the surrounding water.
300
What is broadcast spawning?
When species release millions of eggs and sperm into the water, and have no further interaction with their offspring.
300
What is the difference between Poikilotherms, ectotherms, and endotherms?
Poikilotherms- temperatures change with that of the environment.
Ectotherms- "cold-blooded"
Endotherms- "warm-blooded"
400
A complex framework inside cells made of protein fibers.
Cytoskeleton
400
Three main domains in the classification pyramid
Bacteria, Archaea, and Eukarya
400
What is the main difference between saltwater fish and freshwater fish?
Saltwater fish excrete guts through their gills, guts, and urine.
Freshwater fish do not live in a salty environment so they generally do not have to excrete any salts.
400
Female gonads vs. Male gonads
Ovaries vs testes
400
Explain natural selection.
Where the best adapted individuals, those most successful at meeting the challenges of the environment, produce more offspring on average than those that are not so well-adapted.
500
An arrangement of sacs and membranes in many eukaryotic cells that is involved in collecting and transporting molecules.
Golgi Apparatus
500
The evolutionary history of a species or other taxon.
Definition of Phylogeny
500
What is active transport?
The transfer of substances across membranes by a cell against a concentration gradient.
500
Mitosis vs. Meiosis
Mitosis- The cell division in which a cell divides into two daughter cells that are identical to the original cell.
Meiosis- Cell division that results in the formation of gametes.
500
What is binomial nomenclature?
A system of naming species using two names, the first of which refers to the genus.
