Which of the following is an attribute of living things? - correct answer-
They must be capable of acquiring adaptations through evolution.
Which of the following is NOT an attribute of living things? - correct answer-
All living things require oxygen.
Which of the following statements best describes the phenomenon of "emergence"? - correct answer-
The whole is greater than the sum of the parts.
Which of the following domains is prokaryotic? - correct answer-Archaea
Which type of organisms within the domain Eukarya is composed of organisms that are generally unicell
ular (single-celled)? - correct answer-protists
Eukaryotic organisms that decompose dead organisms and absorb the nutrients are generally found in w
hich kingdom? - correct answer-Fungi
Evolution tends to act at which of the following levels? - correct answer-population
Which of the following statements most clearly demonstrates inductive reasoning? - correct answer-
If the animals observed require organic molecules as nutrients, then it can be concluded that all animals
require organic molecules as nutrients.
At which point in a study is a scientific investigator most likely to use deductive reasoning? -
correct answer-in establishing a test of a hypothesis
Which of the following four statements, if any, is true regardingPessential elements and living organisms?
- correct answer-
Although all forms of life require iron, other elements are required only by certain species.
, Consider this statement: Concentrations of trace elements in an environment above what is required by
organisms generally have no effect on those organisms. Which of the following is a valid response to this
statement? - correct answer-
False. Elevated concentrations of some trace elements such as cobalt and chromium can be toxic.
When do hydrogen bonds occur? - correct answer-
when partial opposite charges on molecules come close enough to attract each other
What is the role of van der Waals interactions in biological molecules? - correct answer-
Although they are weak bonds, van der Waals interactions help to reinforce the three-
dimensional shapes of large molecules.

number of molecules.
Adhesion is best described as which of the followingP- correct answer-
the clinging of one substance to another substance
Which action would involve the greatest transfer of heat? - correct answer-
condensing 5 g of steam to liquid water
The amount of heat required to change the temperature of 1 g of any substance by 1°C isPdefined as
. - correct answer-the specific heat of that substance
Water has than other liquids such as ethanol , reflecting its capacity to absorb large amount
s of heat. - correct answer-a higher boiling point
Sucrose has a molecular mass of 342 daltons. To make a 2-
molar (2 M) solution of sucrose, . - correct answer-
stir 342 g of sucrose in water to dissolve the sugar, and then add enough water to bring the total volume
of the solution up to 0.5 L
