AP Bio Natural Selection

natural selection

• is the cause of evolution

• gives organisms less fitness

• is the result of random mating

• caused by human interference

a niche

• is an organism's place in the environment

• when humans cause new breeds of plants and animals

• a measure of an organism's ability to survive and reproduce

• survival of the least fit

mutations are

• the biggest cause of genetic variation

• are a creation of the environment

• are always detramental

• reduce an organism's fitness

competition in biology is

• two organisms fighting over the same resources

• a thing when two men fight over the same rack in the weight room

• any sporting event where there are winners and losers

• love

which is not an example of biotic factor

• air quality

• predators

• prey

• water borne pathogens

stable environments

• dont cause mutations

• cause mutations

• encourage evolution

• discourage evolution

Volcanic eruptions, mass floods, earthquakes can cause

• over preparation

• under preparation

• ecosystems to rapidly change

• one organism to cause all others to go to extinction

Selective pressures

• are put on by humans

• are abiotic and biotic factors that the environment add onto species

• dont encourage evoultion

• none of the above

know about the moths

• yes

• no

• your mom

• 10 bucks kelci chose your mom

selective breeding, or artificial selection is

• human breeding to make better crops and farm animals

• the same as natural selection

• animals choose what traits to pass on

• a non-disjunction in a chromosome
