Question 1

David Blehert and his research team captured 117 healthy bats to study in the laboratory and divided them into 4 groups.Group 1 was housed in an area free from Geomyces destructans.Group 2 was housed in an area that shared the same air as bats infected with WNS,but they did not have direct contact with the infected bats.Group 3 was housed in direct contact with other bats infected with WNS.Group 4 was directly exposed to Geomyces destructans when it was applied to their wings.During the study period the bats were monitored for signs of WNS.What is the specific hypothesis being tested by the inclusion of group 4 in this experiment?

Accepted Answer

A)  Geomyces destructans causes WNS,and it can be transmitted through the air.
B)  Geomyces destructans causes WNS,and it is only transmitted by direct contact with other infected bats.
C)  Geomyces destructans causes WNS,and it can be transmitted by direct contact with the fungus;no contact with infected bats is needed for transmission of the fungus.
D)  Group 4 is the control.

Question 5

Recently,beekeepers have noticed an alarming and sudden disappearance of honeybees from their hives.Some beekeepers and environmentalists worry that crops genetically engineered to contain the gene for the Bt insecticidal toxin may be killing the bees.Which of these experiments tests the hypothesis that Bt is killing the bees?

Accepted Answer

A)  Spraying Bt toxin on a field and counting the number of bees present before and after spraying.
B)  Collecting hundreds of bees.Half of the bees would be kept in a facility with plants genetically engineered to contain the gene for Bt toxin while the other half would be kept in a facility with plants not genetically engineered to contain the gene for Bt toxin.The survival rate for both sets of bees would be calculated and compared.
C)  Collecting hundreds of bees and spraying half of them with Bt toxin while the other half is not sprayed with Bt toxin.The survival rate for both sets of bees would be calculated and compared.
D)  The number of bees in two adjacent fields would be counted before and after spraying one of the fields with Bt toxin.The survival rate of bees in both fields would be calculated and compared.

Question 6

In 1890,Robert Koch developed a hypothesis regarding the cause of communicable diseases.He designed an experiment and collected data that supported his hypothesis.Later,his experiment was repeated by many other scientists who used other pathogens and documented similar results that not only supported their hypotheses but also supported Koch's original hypothesis.These many experiments that supported multiple hypotheses regarding the cause of communicable diseases contributed to the development of the

Accepted Answer

A)  theory of evolution.
B)  germ theory of disease.
C)  theory of relativity.
D)  law of gravity.

Question 7

Match the correct term(s)  with the sentence.
-________ your results to fellow scientists for their review and input.

Accepted Answer

A)  tests
B)  communicate
C)  accept, reject, or modify
D)  observe
E)  analyzeF) hypothesisG) predictions

Question 8

The roots of a sunflower plant growing downwards while the shoot grows upwards and the flower turns towards the sun are examples of what characteristic of all living organisms?

Accepted Answer

A)  They reproduce using DNA.
B)  They evolve through time.
C)  They make their own energy.
D)  They sense the environment and respond to it.

Question 9

Scientific understanding can always be challenged,and even changed,with new ways of observing and with different interpretations.For example,new tools and techniques have resulted in new observations and the discovery of additional information.This has resulted in revised ways of understanding how molecules are moved across the plasma membrane of cells.Hence,there is no certainty in science,only degrees of probability (likelihood) and potential for change.In light of this understanding,which of the following statements is most meaningful?

Accepted Answer

A)  Scientific knowledge is absolute knowledge.
B)  Scientific knowledge is necessarily contingent knowledge.
C)  Scientific knowledge is a static and unchanging collection of facts.
D)  Scientific knowledge is rigid collection of invariable facts.

Question 10

Is it possible for scientists to study events that happened or animals/plants that lived millions of years ago?

Accepted Answer

A)  Yes.Apply the laws of physics and nature that we know exist today to evaluate the evidence of past events.For example,observe modern animal behavior,structure,and function,and compare them to the structures of fossilized animals to deduce the function of the fossilized structures.
B)  No.The laws of physics that exist today are not the same laws of physics that existed in the past,so there is no way to compare plant or animal fossils to those of modern organisms and deduce the function of fossilized structures.
C)  Yes.Genetic manipulation of fossils allows scientists to directly test metabolic and behavioral characteristics of plants and animals from the past.
D)  No.There is no way to analyze plant or animal fossils that lived millions of years ago because the laws of nature that exist today have changed dramatically from the past.

Question 11

Land biomes are most commonly defined by

Accepted Answer

A)  their climate,physical characteristics,and dominant animal life.
B)  only the dominant plant life in them.
C)  the dominant plant life that influences the dominant animal life in them.
D)  their climate and physical characteristics which influence the dominant plant life and,subsequently,animal life in them. D

Question 12

When scientists generate a single informed,logical,and plausible explanation for a question and observations of the natural world,they are proposing a scientific

Accepted Answer

A)  hypothesis.
B)  observation.
C)  theory.
D)  correlation.

Question 13

After observing that students who regularly attend class appear to be making good grades,I propose the hypothesis that regular class attendance increases the probability that students earn higher grades.If I attend classes regularly this semester,I should make higher grades than I did last semester when I often missed class.This is a ________.
