What are the two different components of an environment, and how do you distinguish them?
abiotic and biotic Biotic components are living components, while abiotic components are nonliving components.
100
These are segments of DNA.
genes
100
What are the three basic plant organs?
roots, stems, and leaves
100
What is gradualism?
idea that profound change can take place through cumulative effect of slow but continuous processes
100
What are found in the cell?
organelles
200
This behavior is rare in organisms, and reduces an individual organism's fitness, but increases the fitness of other individuals in a population.
altruistic behavior
200
Methods include budding, binary fission, and mitotic cell divison.
asexual reproduction
200
What regulates rate of transpiration?
stomata
200
What are homologous structures?
similar stuctures but different functions
200
What is the plasma membrane?
phospholipid bilayer used by the cell to "sort" materials coming in and going out
300
What are the three types of dispersion?
random, uniform, and clumped
300
Explain what a somatic cell is.
any cell other than a gamete
300
What are xerophytes?
plants adaptes to arid climates
300
What is needed for Hardy-Weinberg Equilibrium?
large population, no gene flow, no mutations, random mating, and no natural selection
300
What organelles are used to produce energy for the cell?
mitochondria and chloroplasts
400
Factors that regulate populations; including competition for resources, territoriality, health, predations, toxic wastes, and intrinsic factors.
density-dependent factors
400
Prophase -> Metaphase -> Anaphase-> Telophase

500
Includes parasitism, mutualism, and commensalism.
symbiotic relationships
500
Each pair of alleles segregates independently of other pairs of alleles during gamete formation.
law of independent assortment
500
What are epiphytes?
plants that sustains itself but grows on another plant
500
What are the different modes of selection?
directional, disruptive, and stabilizing
500
What purpose do lysosomes have?
digesting materials in the cell, and breakin down damaged organelles
