Is it important for scientists to communicate their results tofellow scientists?
Yes. Scientists want to receive recognition and monetary rewardfor their work.
No. There is no reason for scientists to communicate theirresults to fellow scientists.
Yes. The quality and accuracy of the scientific work can beenhanced by input, further review, and possibly even repetition byother scientists working in the same field.
No. Communication between scientists is discouraged because itcan confuse the details of the experiments.
When a germ cell has completed both rounds of meiosis, cells arecreated which are
diploid, and each sister chromatid is in one of two differentdaughter cells.
diploid, and one of each homologous chromosome pair is in one oftwo different daughter cells.
haploid, and each sister chromatid is in one of four differentdaughter cells.
none of the answers are correct
Ice floats on water because
the crystal structure of ice is more regular than that seen inliquid water.
the distance between water molecules in ice is greater than inliquid water.
the cool temperature of ice reduces the extent of molecularmotion relative to liquid water.
when ice forms, the hydrogen bond in the water molecule becomesnonpolar; ice behaves like oil.
If a genetic disorder is caused by a dominant allele,individuals with which of the following genotypes would be affectedby the disorder?
AA and aa
aa and Aa
AA and Aa
AA, Aa, and aa
Which of the following examples indicates a situation where theresearcher is MOST likely to have a possible bias regarding his orher work?
A researcher, funded by a pharmaceutical company, is testing theclinical effectiveness and safety of a new vaccine.
A researcher, funded by a public grant, is testing the clinicaleffectiveness and safety of a new vaccine.
A federally funded researcher is working on developing agenetically engineered microbe to quickly digest oil spills.
A privately funded researcher is working on developing agenetically engineered and patented microbe to quickly digest oilspills. If successful, the microbe would be marketed worldwide.
What information in a pedigree would indicate a condition islikely dominant?
Twenty-five percent of the individuals in the pedigree have thecondition.
Two-thirds of the affected individuals are females.
None of the affected individuals have unaffected parents.
Most of the affected individuals are males.
If DNA polymerase did not have the ability to proofread, thenDNA replication would
not proceed at all.
proceed more slowly.
result in more mutations.
result in additional copies of DNA.

A chemical reaction that uses ATP to build cellular componentsis
catabolic.
anabolic.
photosynthetic.
respiration.
Which of the following would be a fact?
Specific pathogens are directly responsible for specificdiseases and conditions.
A fungal infection is solely responsible for the spread of whitenoses and associated higher mortality across bat populations andspecies.
Bats with white noses have been observed in the wild.
A fungal infection causes bats to wake up repeatedly during thewinter and use up their fat reserves.
Which of the following is a similarity between photosynthesisand respiration?
Neither is a metabolic process.
They are both metabolic processes.
Neither is an anabolic process.
They are both mainly anabolic processes.
The endoplasmic reticulum (ER) is a single membrane continuouswith the nuclear envelope and a series of interconnected sacsthroughout the cell. Why might it be beneficial to the cell for theER to be continuous with the nuclear envelope? It might bebeneficial for the ER and nuclear envelope to be connected becauseit
takes less energy, DNA, carbohydrates, and phospholipids for theER to synthesize centrioles.
is easier for messages to get from the nucleus to the ER whereproteins and lipids are made for the cell; this would require theuse of less energy.
would make it easier for the nucleus to actually carry outcellular respiration.
would make it easier for the ER to carry out photosynthesis.
