Warts result when certain viruses cause skin cells to reproduce at a high rate. This rapid reproduction of skin cells is due to the viruses stimulating
mitotic cell division
100
Some variation must be present in a population in order for natural selection to take place. These variations arise from mutations in the DNA and
sorting of chromosomes during sexual reproduction
100
Thousands of genetically identical trees have been discovered growing in a remote, undisturbed mountain area in Colorado. These trees are most likely the result of
asexual reproduction
100
What is a heterotroph
an organism that needs to find or get its food
100
As a result of sexual reproduction, an organism can pass a gene mutation to its offspring if the mutation occurs in
a gamete
200
Which statement concerning sexual reproduction is correct? - - It is not necessary in order for the individual to survive. The offspring are identical to the parent.
It is not necessary in order for the individual to survive.
200
Asexual reproduction produces offspring that each contain
genetic information from one parent
200
Reproduction in humans usually requires
gametes with chromosomes that are not paired
200
Organisms whose cells lack nuclei
Prokaryote
200
Which situation would most likely result in the highest rate of natural selection? -- reproduction of organisms in an unchanging environment with little competition and few --reproduction of organisms exhibiting genetic differences due to mutations and genetic recombinations in a changing environment
reproduction of organisms exhibiting genetic differences due to mutations and genetic recombinations in a changing environment
300
Which characteristics of a population would most likely indicate the lowest potential for evolutionary change in that population?
asexual reproduction and few mutations
300
Which organism would most likely have new gene combinations?
a hamster resulting from sexual reproduction
300
Species of bacteria can evolve more quickly than species of mammals because bacteria have
higher rates of reproduction
300
What normally happens immediately after fertilization in sexual reproduction?
division of cells resulting in the development of an embryo from a zygote
300
The occurrence of the same blood protein in a group of species provides evidence that these species
descended from a common ancestor
400
Which statement describes asexual reproduction? --Mutations are not passed from generation to generation. --Adaptive traits are usually passed from parent to offspring without genetic modification.
Adaptive traits are usually passed from parent to offspring without genetic modification.

A particular species of shark normally reproduces sexually. In captivity, it was found that a female could also reproduce asexually. One negative result from asexual reproduction is
decreased biodiversity within the species
400
The environment dictates only the direction and extent of evolution.
False
400
Which sequence best represents sexual reproduction? mitosis -> gametes -> zygote -> fertilization gametes->meiosis->mitosis->fertilization fertilization -> gametes -> meiosis -> zygote meiosis -> gametes -> fertilization -> zygote
meiosis -> gametes -> fertilization -> zygote

If the same antibiotic is used too many times, it can become less effective against a certain type of bacteria. This observation is best explained by the
survival and reproduction of unaffected bacteria
500
The human forelimb and the bat forelimb are called?
homologous structures
500
A variation causes the production of an improved variety of apple. What is the best method to use to obtain additional apple trees of this variety in the shortest period of time?
asexual reproduction
500
When food is scares, the number of different beak shapes of finches increases.
True
500
What is the difference between a heterotroph in an autotroph
The difference is the way they find their food source or make their food source
500
Which characteristics of a population would most likely indicate the lowest potential for evolutionary change in that population?
asexual reproduction and few mutations
