QUESTION :Algae in the genus Caulerpa typically grow to a length of over half a meter and have
structures similar to stems, leaves, and roots. Reproduction occurs when adults produce sperm and
eggs that fuse to form offspring. Each adult Caulerpa consists of just a single cell, however. Which of
the following statements is TRUE? - ANS. The existence of Caulerpa is consistent with the cell theory.
QUESTION :Cells are ________ - ANS. characteristic of prokaryotic and eukaryotic organisms
QUESTION :In comparison to eukaryotes, prokaryotes ________ - ANS. are smaller
QUESTION :he structure of double helical DNA ________ - ANS.is used to synthesize messenger RNA
QUESTION :Which of these provides evidence of the common ancestry of all life? - ANS.near
universality of the genetic code
QUESTION :Protists and bacteria are grouped into different domains because ________. -
ANS.protists have a membrane-bounded nucleus, which bacterial cells lack
QUESTION :You have isolated and purified a new species of cells from the rain forest and you want
to place this new species in the appropriate branch of the tree of life. You sequence the ribosomal
RNA genes from these cells and discover that for one particular region of the ribosomal gene (the
rRNA) the RNA sequence is AAUGAAGG. You have sequences from the same region of the ribosomal
genes (the rRNA) from each of the sespecies: bacteria, eukaryote and archaea, which are listed
below.

,bacteria AUAGAUGG
eukaryote AAAGAAGG
archaea AAUGGAGU
Based on these sequence results, to which branch of the tree of life should you assign this new
species? - ANS.eukaryote
QUESTION :Louis Pasteur's experiment had a good design because ________ - ANS.the possible
outcomes led to distinct, unambiguous conclusions
QUESTION :A friend of yours calls to say that his car would not start this morning. He asks foryour
help. You say that you think the battery must be dead. If so, then jump-starting thecar from a good
battery will solve the problem. In doing so, you are ________ - ANS.stating a hypothesis and using
that hypothesis to make a testable prediction
QUESTION :Agrobacterium infects plants and causes them to form tumors. You are asked
todetermine how long a plant must be exposed to these bacteria to become infected.Which of the
following experiments will provide the best data to address that question? - ANS.Measure the
number of tumors formed on plants, which are exposed to a knownconcentration of Agrobacterium
for different lengths of time
QUESTION :Agrobacterium infects plants and causes them to form tumors. You determine
thattumor formation requires a large amount of the plant's energy for tissue formation. Howmight
this change the number of offspring a plant produces, and what is the most likelyexplanation for this
change? - ANS.The number of offspring should decrease, because the plant will divert energy
fromreproduction to tumor formation

,QUESTION :Refer to the paragraph on Redi's experiments. What hypothesis was being tested inthe
initial experiment with open versus sealed jars? - ANS.Maggots do not arise spontaneously, but from
eggs laid by adult flies
QUESTION :Refer to the paragraph on Redi's experiments. In both experiments, flies appearedin all
of the open jars and only in the open jars. Which one of the following statements iscorrect? -
ANS.The experiment supports the hypothesis that maggots arise only from eggs laid byadult flies.
QUESTION :In the process of science, which of these is NOT used to test a hypothesis? - ANS.a
theory
QUESTION :In presenting data that result from an experiment, a group of students show thatmost of
their measurements fall on a straight diagonal line on their graph. However, twoof their data points
are "outliers" and fall far to one side of the expected relationship.What should they do? - ANS.Show
all results obtained and then try to explore the reason(s) for these outliers.
QUESTION :Why is a scientific topic best discussed by people of varying points of view,
fromdifferent subdisciplines, and representing diverse cultures? - ANS.Robust and critical discussion
between diverse groups improves scientific thinking.
QUESTION :About twenty-five of the 92 natural elements are known to be essential to life. Which4
of these 25 elements make up approximately 96 percent of living matter? - ANS.carbon, hydrogen,
nitrogen, oxygen
QUESTION :Why is each element unique with respect to its chemical properties? Each elementhas a
distinctive ________ - ANS.number of protons
QUESTION :Knowing the atomic mass of an element allows inferences about which of thefollowing?
- ANS.the number of protons plus neutrons in the element

, QUESTION :From its atomic number of 15, it is possible to predict that the phosphorus atom
has________ - ANS.15 protons and 15 electrons
QUESTION :A covalent chemical bond is one in which ________. - ANS.outer-shell electrons of two
atoms are shared so as to satisfactorily fill theirrespective orbitals
QUESTION :Nitrogen (N) is more electronegative than hydrogen (H). Which of the following is
acorrect statement about the atoms in ammonia (NH3)? - ANS.Each hydrogen atom has a partial
positive charge; the nitrogen atom has a partialnegative charge
QUESTION :Bonds between two atoms that are equally electronegative are ________ -
ANS.nonpolar covalent bonds
QUESTION :A covalent bond is likely to be polar when ________. - ANS.one of the atoms sharing
electrons is more electronegative than the other atom
QUESTION :Refer to the following figure to answer the following question.Refer to the figure above
(first three rows of the periodic table). What element hasproperties most similar to carbon? -
ANS.silicon
QUESTION :How many electrons are involved in a single covalent bond? - ANS.two
QUESTION :An atom has four electrons in its valence shell. What types of covalent bonds is
itcapable of forming? - ANS.single, double, or triple
QUESTION :Which of the following is a property of liquid water? Liquid water ________. - ANS.has a
heat of vaporization that is higher than that for most other substances
