What is species richness?
The number of different species in a community.
200
What are the 3 domains of life?
Archaea, Bacteria, and Eukarya.
200
What type of species interaction benefits one organism and has no effect on the other?
Commensalism
200
The observable traits expressed by an organism is its ______, while the underlying genetic material consisting of alleles is an organism's _______.
Phenotype; Genotype
300
What does the Hardy-Weinberg principle assume about a population?
An infinitely large population and no forces of evolution.
300
The 4 "concepts" for defining species are:
Morphological, biological, ecological, and phylogenetic.
300
What are the 3 fundamental processes of development?
Growth, differentiation, and morphogenesis.
300
What does a negative population growth mean?
The death rate is higher than the birth rate
300
A common ancestor and only some of its descendants is known as a ____ group.
Paraphyletic
400
Is "survival of the fittest" an accurate description of evolution? Why or why not?
No! Evolution does NOT occur unless reproduction occurs, survival of an individual is not what matters.

What are the 3 post-zygotic isolating mechanisms?
Reduced hybrid viability, reduced hybrid fertility, and hybrid breakdown.

What are the evolutionary advantages of segmentation?
- Flexible movement
- More resistant to injuries
- Drive evolutionary diversification
400
What are the characteristics of a Type III survivorship curve?
Few organisms survive to adulthood, large number of offspring, low parental care
