Exam 1: The Nature of Science

Match the following terms with the corresponding characteristic of life. -maintaining a relatively constant internal environment

Researchers hypothesized that a North American fungus not only caused symptoms of white-nose syndrome (WNS)but also caused death.The results from their experiment are shown in the graph below.Based on this graph,which of the following hypotheses would be the MOST logical hypothesis for further studies?

The hypothesis that there is a common ancestor to all living organisms is strengthened by what observation?

Match the following terms with the corresponding characteristic of life. -a change in the characteristics of a group of organisms over time

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

Which of the following represents conducting an experiment?

Experimentation is the primary,but not only,means used to verify or refute the ________ made by a hypothesis.

Read each statement and identify whether the statement is a scientific fact,a scientific theory,or an opinion.Choices may be used more than once or not at all. Dead mice within a cave where bats are infected with white-nose syndrome (WNS) have white fuzz on their noses that appears to be similar to the white fuzz seen on the noses of bats ill with WNS. A researcher hypothesizes that mice are also susceptible to WNS when they live in close contact with infected bats. To test this hypothesis, the researcher captures 50 healthy mice and randomly separates them into two groups. One group is housed in an area that contains healthy bats. The other group of mice is housed in an enclosure that contains bats that have WNS. The mice in both groups are monitored for signs of WNS. -Mice housed in an area with healthy bats.

David Blehert and his research team captured 117 healthy bats to study in the laboratory and divided them into four 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 these bats did not have direct contact with the infected bats.Group 3 was housed in direct contact with other bats infected with WNS.Bats in group 4 were directly exposed to Geomyces destructans when researchers applied it to the bats' 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?

Match the following terms with the corresponding characteristic of life. -the way organisms capture,store,and use energy from the environment

Which of the following questions could NOT be used to develop a testable hypothesis?

Match the correct terms with the sentences below. -________and ask questions about the natural world.

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

Recently,beekeepers have noticed an alarming and sudden disappearance of honeybees from their hives.Some beekeepers and environmentalists worry that crops genetically engineered to produce Bt insecticidal toxin may be killing the bees.Without data from a scientific experiment,is it reasonable to state that Bt-containing crops are responsible for the loss of honeybees?
