BIO 160 CHAPTER 1 PRACTICE TEST QUESTIONS AND
VERIFIED ANSWERS; 100% CORRECT; GRADE A
**A hypothesis must be testable and falsifiable to be
scientifically valid. Being testable and falsifiable means that
_____. - correct answer- some conceivable observation or
experiment could reveal whether a given hypothesis is incorrect
**At which point is a scientific investigator most likely to use
deductive reasoning? - correct answer- in establishing a test
of a hypothesis
**Emergent properties of living systems are defined as
properties that _____. - correct answer- are due to the
arrangement and interactions of parts as complexity increases
**In an ecosystem, nutrients _____ and energy _____. - correct
answer- cycle ... flows through
**Natural selection tends to act at which of the following levels?
- correct answer- population
, **Which of the following is NOT an example of emergence? -
correct answer- None of the listed responses is correct.
**Which of the following statements best describes what is
meant by "emergence"? - correct answer- The whole is
greater than the sum of the parts.
**Which series of terms is in the correct sequence of biological
organization, from the simplest to the most complex? - correct
answer- cell, tissue, organ, population, community
A company was testing a new drug it thought would help
decrease the risk of transmission of viruses from mother to
fetus. In an experiment to test the compound, an investigator
gave 400 pregnant female rats a small dose of the experimental
drug and inoculated each with a type of virus known to cause
disease in rats. At the same time, 400 other pregnant rats were
given only the virus. Of the rat pups born to the females that
received both the virus and the drug, 203 showed no symptoms
of the disease; 205 rat pups born to the virus-only females
showed symptoms. From these data, we can best conclude
_____. - correct answer- that the drug seems to have little
effect on viral transmission at the dosage given
