BIO 1500 FINAL EXAM- BANKS TEST 1
QUESTIONS AND ANSWERS
contains the pyrimidine uracil - ANSWER-RNA
polymer is in a double helix structure - ANSWER-DNA
nucleotide contains ribose - ANSWER-RNA
used as a structural component of insect exoskeletons - ANSWER-
generally defined by non polar properties - ANSWER-lipid
Water molecules are unique in that they can form ______ bonds with each other,
because the electrical charge distribution is not even: the oxygen atom is ____
charged, while the hydrogen atoms are _______ charged. - ANSWER-hydrogen,
negatively, positively
The bonding described in the previous question allows for the phenomenon known
as - ANSWER-cohesion
An iron atom has ____ protons, and most atoms have _____ neutrons. - ANSWER-
26, 30
Relatively speaking, how would you describe the electronegativity of an urn atom in
relation to an oxygen atom? - ANSWER-Iron is less electronegative than oxygen
Which of the following representations would most clearly illustrate the molecular
interactions the researchers were studying?
Acidity is measured in pH units. Which of the following is true of a solution that has a
pH of 10? - ANSWER-The concentration of hydrogen ions is 10-10M
The following are the steps in natural systems (for example in human blood and in
the oceans) that describe how CO2 impacts pH. Put these steps in their correct
order. - ANSWER-II, IV, I, III - carbon dioxide goes into solution, carbonic acid is
formed, carbonic acid partially dissociates into bicarbonate and H+, Protons lower
the pH
If lactate can contribute to the acidity of the surrounding environment, which of the
following is most likely true?
In an experiment to test if alkaline solutions could help treat cancer, mice were
injected with cancerous cells and provided with regular water(control) or water
containing sodium bicarbonate... what was the independent variable? - ANSWER-
The type of water provided
