|
All of the members of an interbreeding group of organisms in a local area make up a POPULATION
|
|
Sizes of natural populations remain relatively stable over time because DEATH limits population numbers.
|

|
|
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.
|
What occured during the 1700s that resulted in human populations growing at a higher rate? MORE CONTROL OVER THE FOOD SUPPLY, SUPERIOR WEAPONS WERE AVAILABLE TO WARD OFF PREDATORS, MANY DISEASES BEGAN TO BE CONTROLLED

At what rate is the human population growing each year? 1.3%
|
|
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
