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.
Akk 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.
Which is a step in the process of producing transgenic bacteria?
A plasmid is used to replace a faulty gene in a human cell.
A chain of bacterial amino acids is inserted into human DNA.
A human gene is inserted into a bacterial plasmid
A mutation is produced in a bacteria cell.

Couple W
Couple Z
Couple Y
Couple X
Which would most likely produce a mutation that is passed on to offspring?
Radiation changing the DNA sequence in skin cells.
a gamete with an extra chromosome
tobacco smoke altering the genes in lung cells
exposure to chemicals altering nerve cell function
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.

osmosis
diffusion
How are prokaryotic and eukaryotic cells similar?
Both contain a nucleus.
Both contain ribosomes
Both contain membrane-bound organelles
Both contain cell walls,
How does DNA code for proteins in a cell?
by creating a new double helix structure.
by using its phosphate and sugar molecules
by adding more hydrogen bonds to its structure

innate behavior
learned behavior
A field ecologist wants to determine the interactions of various populations of organisms living in a large grassland field. Which method is best for conducting this study?
consulting with local farmers about the diversity of organisms in the field
dividing the field in half, walking over it, counting organisms, and then doubling the numbers.
walking over the entire field, collecting the organisms, and then compiling a total
observing the behaviors of different types of organisms several times during the year.
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
If worldwide deforestation is not regulated, what could most likely result?
Acid rain could lower the pH of rivers and lakes to dangerous levels for aquatic life.
CO2 levels in the atmosphere could increase and contribute to global warming problems.
Plants and animals could better adapted to living in desert conditions.
Future generations of humans could have an excess of wood and paper products.
How would overexposure to X-rays affect most animal cells?
It would increase cell specialization in organs.
It would change the sequence of DNA nucleotides in affected cells.
It would produce new nucleotides for DNA molecules
It would cause an increase in red blood cell production.
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.
