Biology EOC Practice Test
If a company claims that it's product has been proven scientifically, which of the
following should have taken place if the results are considered to be reliable? - Correct
Answers -Results should have been peer reviewed and repeated producing the same
findings
Based on your knowledge of scientific investigations, which stage of scientific
investigation did the invention of the microscope significantly advance? - Correct
Answers -Gathering the data for the investigation
A student is conducting an investigation to determine the effect of temperature on the
metabolism of yeast. Yeast and sugar are added to water, the gas produced it captured,
and it's volume recorded. Which variable should be held constant during this
investigation? - Correct Answers -Mass of yeast and mass of sugar
Scientific law and scientific theory are similar in which way? - Correct Answers -They
both represent a large amount of scientific investigation and evidence
To help patients replenish body fluids quickly during an illness, doctors need to
understand how cells behave in their environment m. How do doctors have confidence
in what they know about how cells behave? - Correct Answers -Cell theory has been
tested, refined, and observed of being true over hundreds of years
Which of the following correctly compares the functions of the vas deferens and the
Fallopian tubes? - Correct Answers -Sperm travels through the vas deferens, and eggs
travel through the fallopian tubes.
Normally, the temperature inside the scrotum is slightly lower than normal body
temperature. What do you predict would happen if the temperature inside the scrotum
were a few degrees higher than normal body temperature instead? - Correct Answers -
The sperm would not be able to develop properly
Which of the following correctly explains how crossing over benefits organisms that
reproduce sexually? - Correct Answers -It increases genetic variation in offspring.
Which of the following would be the best way to detect whether someone was infected
with a virus, like HIV? - Correct Answers -Check for the presence of antibodies in the
blood.
Which of the following best describes a result of the polar nature of water molecules? -
Correct Answers -Ionic compounds dissolve easily in water.
, Water has a much higher specific heat than most other covalent compounds. What do
you predict might happen if water had a low specific heat instead? - Correct Answers -
Organisms that are sensitive to changes in temperature would die.
In which of the following circumstances would it be most likely for large organic
molecules to form during a laboratory investigation? - Correct Answers -If RNA
segments that could act as catalysts formed
Assume a group of scientists has managed to set up an experiment simulating the
conditions of early Earth that resulted in a cell with DNA using RNA to produce proteins
from amino acids as modern cells do. What conclusion could they draw from this
experiment? - Correct Answers -It is possible for a cell similar to a modern cell to form
under the conditions of the experiment
A variety of organic molecules have been found in meteorites that have landed on
Earth, including individual amino acids and lipid molecules. To date, however, no
microspheres have been found on these meteorites. Why is it unlikely that microspheres
will ever be found on a meteorite even though lipids can form in them? - Correct
Answers -Groups of lipids will only form into microspheres when they are in liquid water
Which of the following best compares the structure of lipids and carbohydrates? -
Correct Answers -Both consist of carbon, hydrogen, and oxygen, but carbohydrates
have repeating structural units and lipids do not
Which of the following best describes the difference between the functions of nucleic
acids and enzymes? - Correct Answers -Nucleic acids contain the genetic code for
protein synthesis, while enzymes catalyze chemical reactions.
Some proteins catalyze biochemical reactions. If a genetic defect prevented a protein
catalyst from being produced, which of the following do you predict would happen in the
cell? - Correct Answers -The reaction the protein catalyzes would proceed very slowly
or not at all
Which of the following best summarizes why the technological invention of the
microscopes was important to biology? - Correct Answers -It allowed for development of
the cell theory.
Early elements of the cell theory followed soon after the development of Hooke's light
microscope. What does this relationship suggest about the evolution of the cell theory
since Hooke? - Correct Answers -Improvements in technology are closely related to
changes in cell theory
Which of the following characteristics defines a cell as a eukaryote? - Correct Answers -
Having a nucleus
