Evolution
An organism's ability to survive and reproduce
fitness
Prokaryotes lack a ___.
nucleus
Animals that lack a backbone
Invertebrates
Non-native species that are introduced to new environments, spread far beyond the original point of introduction, and cause damage are called
invasive species
The energy needed by living organisms originally comes from
the sun
The process where humans deliberately breed plants or animals to encourage desirable traits.
artificial selection
The two groups of prokaryotic organisms
bacteria
archaea
Pores in plant leaves that allow oxygen and carbon dioxide to be exchanged
Stomata
The maximum number of individuals a habitat can support
carrying capacity
Chondrichthyans (sharks and rays) have skeletons made primarily of
Cartilage
Type of speciation that occurs when two populations are geographically separated and no gene flow can occur
Name of spherical shaped bacterial cells
coccus (cocci)
The symbiotic relationship between plant roots and fungi is known as
Mycorrhizae
Measures the land and resources required to support consumption and waste
ecological footprint
Organisms that maintain their body temperature internally using metabolism and muscle contractions
Endotherms
Type of natural selection that favors both extreme phenotypes over the intermediate.
Disruptive
Using prokaryotic organisms to remove pollutants from water or soil is called
Bioremediation
Complete metamorphosis includes which stage that incomplete metamorphosis does NOT?
Pupa
The over enrichment of water bodies with nutrients like nitrogen and phosphorus
List the taxonomic levels in order from largest (most inclusive) to smallest (most exclusive).
D K P C O F G S
Type of reproductive isolation resulting in speciation that occurs when two species breed at different times of the day or year.
Temporal isolation
Bacteria sharing genetic material directly with one another is called
Conjugation
Organisms that must regulate their body temperature by absorbing heat from the environment.
Ectotherms
Survivorship curve associated with r-selected individuals that produce many offspring with no parental care
Type III
