Exam 1: The Nature of Science

Organize the following concepts in order of broadest interactions between groups to the smallest structure and give a brief explanation of the concepts: biome,biosphere,community,ecosystem,organism,and population.

A scientific hypothesis must be ________; if not,science cannot evaluate it.

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. -White-nose syndrome in bats is a disease that is spreading across the United States.

The caves in upstate New York,where Alan Hicks's team first noticed the deaths of thousands of bats,represent the ________ where the bats lived.

In science,when a hypothesis or group of hypotheses supported by repeated experimental evidence holds true through time,it can be developed into a

A scientific hypothesis must be constructed with which of the following characteristics?

Terrance observes that tomato seeds sprouting in his fresh compost pile seem to grow at a faster rate than tomato seeds that he planted in potting soil that was previously used to grow house plants.Describe an experiment that he could use to test the hypothesis that tomato seeds grown in fresh compost grow faster than those grown in used potting soil.Include information about appropriate variables,treatments,and controls.

Some questions fall outside the realm of science.Which of the following questions could NOT be answered using the scientific method?

Match each term describing a level of biological hierarchy with its proper description.Terms may be used more than once or not at all. -The liver,a body part composed of different tissue types,is considered a(n)________.

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 bats that have WNS.

Which of the following sequences correctly represents the biological hierarchy of a multicellular organism?

A species of butterflies gradually becomes darker in color over many generations; this is an example of which characteristic of living organisms?

Land biomes are most commonly defined by

Match each term describing a level of biological hierarchy with its proper description.Terms may be used more than once or not at all. -The individual building blocks of life,such as oxygen,are referred to as ________.

What characteristic is NOT shared by all living organisms?

Which of these characteristics of living organisms are present in viruses?

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?

Match the correct terms with the sentences below. -________the results.

Match the correct terms with the sentences below. -Generate ________ to test your hypothesis.
