|
|
|
The final stimulus that convinced Darwin to publish his findings came from ALFRED RUSSELL WALLACE who had come to the same conclusion as Darwin from his own travels.
|

|
|
The ecological footprint is: THE AMOUNT OF PRODUCTIVE LAND REQUIRED TO SUPPORT AN INDIVIDUAL IN A COUNTRY.
|
Choose the phrase that best represents microevolutionary change: CHANGES IN GENE FREQUENCY IN A POPULATION
|
|
|
The hypothesis that suggests evolution occurs in spurts, with a great deal of evolutionary activity followed by a period of slower evolution is: PUNCTUATED EQUILIBRIUM
|
Most types of organisms evolve at about the same rate.
FALSE |
|
|
When only a very few individuals give rise to a new population in a new area of favorable habitat, they might differ in appearance from the other, larger population from which they separated. This effect is called the: FOUNDER EFFECT
|
In human infant, there has long been evolution toward having the highest survival rate at a 6-7 pound birth weight. This is an example of: STABILIZING OR BALANCING SELECTION
|
|
|
Sickle-cell anemia in humans is and example of:

When bacterial cell walls are covered with an outer membrane made up of lipoplysaccharide, they are GRAM NEGATIVE
|
|
|
Under harsh environmental conditions, some bacteria are able to form thick-walled ENDOSPORES to protect them for up to hundreds of years until conditions improve.
|
Prokaryotes that obtain their energy by oxidizing inorganic substances, such aas prokaryotes that oxidize hydrogen sulfide in volcanic vents, are this CHEMOAUTOTROPHS
|
|
|
THERMOACIDOPHILES are archaea that live in hot, acidic springs
|
VIRUSES consist of a corre of segments of DNA or RNA surrounded by a protein coat.
|

Viruses enter animal cell by ENDOCYTOSIS
|
|
|
The HIV enzyme REVERSE TRANSCRIPTASE manufactured a DNA copy of the virus once it is inside the human cell.
|
An infectious particle made from protein that causes animal brain dieseases is called a PRION
|
|
|
Darwin's book was entitled ORIGIN OF SPECIES
|
Major terrestrial assemblages with similarly adapted plants, animals, and microorganisms that occur over wide geographical areas with distinct physical characteristics are reffered to as BIOMES
|
|
|
A population ultimately stabilizes at a certain size, called CARRYING CAPACITY of the particular place where the population lives
|
The highest most inclusive level of our current classification scheme is DOMAIN
|
|
|
In the scientific name, Homo sapiens, "Homo" indicated the GENUS of the organism, while "sapiens" indicated its SPECIES
|
Evolution and ecology are two key-concepts
|
|
|
EVOLUTION: changes that occur in organisms' traits over time
|
ECOLOGY: how organisms live in their environment
|
|
|
The great diversity of lofe on earth is the result of EVOLUTION
|
EVOLUTION can be said to be the consequece of ecology over time
