C. The inability of a species to continue to reproduce
D. Sympatric distribution with considerable amounts of gene flow
A. Allopatric distribution
Which of the following things evolve?
A. The individual
B. The sperm/egg cell
C. The population
D. The gene
C. The population
Another gotten wrong, so I know for sure D. The gene is wrong
One type of evidence that supportsthat life existed in the past is a

B. Fossil
C. Variation
D. Selection
B. Fossil
Charles Lyell was a scientist that influenced Darwin, why was his influence on Darwin?
A. Populations struggle and compete for resources
B. Produced a theory similar to Darwin and forced Darwin to publish it
C. Traits can be inherited overtime and passed to the next generation
D. The earth formed very gradually over a long period of time (millions of years)
D. The earth formed very gradually of a long period of time (millions of years)
A species is defined as
A. Organisms that look the same that can breed and produce fertile offspring
B. Organisms that look the same that cannot breed
C. Organisms that look alike that cannot breed or produce fertile offspring
D. Organisms for a different genus that can breed
A. Organisms that look the same and produce fertile offspring
Adaptive radiation:
A: is when many new species evolve from a common ancestor species to fill available niches
B. Is when a mutation in Cardinal causes the cardinals to evolve into new species
C. Is when a salamander gets separated from its population and evolves into a new species
D. Is when hummingbirds evolve different sizes beaks to feed from tubule flowers
A. Is when new species evolve from common ancestor species to fill available niches
Which of the following is NOT on of the conditions in the Hardy-Weinberg theorem
A. No migration
B. No mutation
C. No natural selection
D. Mating is not random
D. Mating is not random
Got wrong, so all I know is that C is wrong answer
Why is genetic variation important from an evolutionary standpoint?
A. If all organisms were the same they sold be able to adapt fast to their environments. Genetics variation leads to slower evolution
B. If all organisms were the same they would better be able to defend against diseases and pathogens. Genitive variations makes it harder
C. If all organisms were the Sam evolution would happen more efficiently. Genetic variation causes slower evolution
D. If all organisms were the same, the whole population would be subject tondisease and different pathogens and possible become extinct. Genetic variation protects against this.
D. If all organisms were the same, the whole population would be subject to disease and different pathogens and possibly become extinct. Genetic variation protects against this.
Modern species of snails of similar types are much like those thy lived 390 million years ago. A likely reason for this is that…
A. Mutations do not occur in these snail species
B. Snails have only a small number of genes
C. Snails have no predators
D. The environment On my way! Hitch they live has changed very little and remained stable
D. The environment in which they live has changed very little and remained stable
