BIO 107 EXAM 5 QUESTIONS AND
ANSWERS
Which one of the following is a problem associated with traditional vaccines as opposed
to vaccines produced by transgenic organisms? - Answer-Traditional vaccines may
result in disease symptoms because they contain killed or weakened organisms.
Insertion of a gene into another organism's DNA so that it can be transferred to another
organism like a bacterium is called - Answer-vector transfer.
Which one of the following genetically engineered vaccines is presently on the market?
- Answer-vaccine for hepatitis B
Pharmaceutical companies prefer to genetically engineer large animals with human
genes because it may be possible to obtain large amounts of the resulting protein from
the animals' - Answer-milk.
One of the main problems associated with treating human diseases through gene
therapy is - Answer-finding a delivery system that would target specific cell types.
The first successful treatment of a human genetic disorder through gene therapy was
with a disorder known as - Answer-severe combined immunodeficiency disease.
The first successful treatment of a genetic disorder by gene therapy was the curing of a
4-year-old girl who had severe combined immunodeficiency disease. Because the
engineered cells did not live forever, this child supplemented her treatment with regular
doses of - Answer-adenosine deaminase (ADA).
Gene therapy is currently under investigation as a possible way to cure cystic fibrosis.
How is the viral vector carrying the normal gene delivered to the affected cells? -
Answer-nasal spray
Rising atmospheric concentrations of greenhouse gasses are causing which of the
following two phenomena to occur? - Answer-global warming and global climate change
The two countries that are the largest emitters of greenhouse gasses are - Answer-
China and the United States of America.
The major concerns regarding the effects of air pollution fall into the areas of smog, acid
rain, destruction of the ozone layer, and - Answer-global warming.
, Gases such as nitrous oxide and carbon dioxide are called greenhouse gases because
they - Answer-permit sunlight to enter but trap the heat energy in the atmosphere.
The ozone layer can be destroyed by pollutants such as - Answer-CFCs.
The main human activities that have raised atmospheric CO2 levels are - Answer-
deforestation and burning fossil fuels.
Certain gases in the upper atmosphere allow sunlight to pass through to Earth's
surface, but prevent heat from escaping. This is known as - Answer-the greenhouse
effect.
The largest hole in the ozone layer occurs in the stratospheric layer over - Answer-
Antarctica.
The greenhouse effect is a natural and important phenomenon because it - Answer-
maintains the surface temperature on Earth.
To reduce the extent of this damaging phenomenon, many power plants have been
required to install systems to remove and capture sulfur dioxide from their emissions -
Answer-acid rain
Surface and aquifer freshwater sources hold what percent of the Earth's total water? -
Answer-less than 1%
Eutrophication of a lake most likely is the result of - Answer-excessive concentrations of
organic and inorganic nutrients
Which one of the following statements is TRUE regarding the water on Earth? - Answer-
Some semiarid and desert regions of the world have reached carrying capacity for
humans due to the shortage of water.
Toxicants occurring in aquatic ecosystems are highly subjected to biological
magnification, meaning the - Answer-pollutants occur in higher concentrations in tissues
of organisms higher up the food chain.
All of the following statements accurately describe eutrophication EXCEPT which one? -
Answer-Eutrophication is beneficial and enhances the diversity of life-forms in a body of
water.
According to public health officials, all of the following may be caused by water
pollutants EXCEPT which one? - Answer-autoimmune disorders
Which of the following pollutants is generally stored in dry locations because they
remain a potential problem for thousands of years? - Answer-radioactive waste
