What will most likely be the result if all of the mitochondria are removed from a plant cell?
It will be unable to carry out respiration.
It will lose water through osmosis.
It will break down the ribosomes in the cell.
It will be unable to photosynthesize.
Why is meiosis important for sexual reproduction?
It allows the zygote formed from fertilization to have triple the chromosome number of the organism.
It allows gametes to have twice the original number of chromosomes of the organism.
It allows gametes to have half the original number of chromosomes of the organism.
It allows the zygote formed from fertilization to have half the original number of chromosomes of the organism.
Which technique would most likely be used by forensic scientists?
gene cloning
gene therapy
DNA fingerprinting
karyotyping

A freshwater plant is placed in a container of saltwater. What will most likely happen to the cells of the plant?
They will swell because water will move into them.
They will swell because salt will move into them.
They will shrink because water will move out of them.
They will shrink because salt will move out of them.
The construction of a new coal-burning power plant would have the greatest impact on which environmental issue?
depletion of the ozone
production of acid rain
release of radiation
increase in deforestation
The inheritance of short wings in Drosophila fruit flies is an x-linked, recessive trait. Which would most likely result if a short-winged female mates with a long-winged male?
All offspring will be short-winged
All females will be long-winged, and all males will be short-winged.
All females will be short-winged, and all males will be long-winged.
Half of the males and females will be short-winged, and half will be long-winged.
A large population of cockroaches was sprayed with an insecticide. A few of the cockroaches survived and produced a population of cockroaches that was resistant to this spray. What can best be inferred from this example?
A species will adapt no matter what the environment.
The environment has no effect on the survival of an organism.
Insecticides cause mutations that are passed on to the next generation.
Individuals with favorable variations survive and reproduce.
At night, moths travel toward light. Which type of behavior does this describe?
habituation
imprinting
innate behavior
learned behavior
Which environmental factor would cause the greatest decrease in the number of species of plants and animals living in some of the lakes in the United States?
increase in dissolved oxygen levels
global warming
ozone destruction
acid rain
How are sexual reproduction and asexual reproduction different?
Sexual reproduction produces offspring identical to the parents, but asexual reproduction produces offspring with traits from both parents.
Asexual reproduction produces offspring identical to the parents, but sexual reproduction produces offspring with traits from both parents.
Sexual reproduction only occurs in multicellular organisms, but asexual reproduction only occurs in unicellular organisms.
Asexual reproduction only occurs in multicellular organisms, but sexual reproduction only occurs in unicellular organisms.
Which characteristic is present in offspring produced by sexual reproduction, but is missing in offspring produced by asexual reproduction?
an identical copy of parent chromosomes
twice the number of parent chromosomes
only half the number of parent chromosomes
an independent assortment of parent chromosomes
In which populations does genetic drift most often occur?
in small populations
in large populations
in marine populations
in terrestrial populations
Which factor most affects the order of amino acids in a protein?
the DNA located in the nucleus of the cell
the cell in which the protein is located
the amount of ATP available for the cell’s use
the area in a cell where proteins are produced
Which would be the best evidence that a cell is using active transport to move a substance across its cell membrane?
Substances are moving rapidly across the cell membrane.
ATP is being rapidly consumed near the cellular membrane.
Substances are moving from high to low concentrations.
Substances are moving through channels in the cell membrane.
