FSA PRACTICE TEST QUESTIONS
WITH ALL CORRECT ANSWERS
What can be concluded about the properties of the elements that border the staircase
on the Periodic Table of the Elements? - Answer-these elements have properties of
both metals and nonmetals.
In the modern Periodic Table, what property is used to arrange the elements? - Answer-
atomic number
Why is Cobalt (Co) placed before Nickel (Ni) on the Periodic Table of the Elements
even though it has a higher average atomic mass than nickel? - Answer-Nickel has one
more proton.
When do scientists choose to use models instead of a controlled experiment? - Answer-
If the object is too large or too small for direct experimentation.
Isopropyl alcohol has a density of 0.786 grams per cubic centimeter (g/cm3). An object
has a mass of 13 grams (g) and a volume of 21 cubic centimeters (cm3). What will
happen when the object is placed into isopropyl alcohol? - Answer-The object will float
because it is less dense than isopropyl alcohol.
Why does the mass of a bowling ball not change when it is transferred from Earth to the
Moon? - Answer-The amount of matter in it stays the same.
What happens to the solubility of a substance when you increase temperature? -
Answer-When you increase temperature, solubility increases.
The Rutherford-Bohr model of the atom was the first really useful model that accurately
illustrated what scientists knew of the structure of atoms in the early 1900s. Based on
today's understanding of atoms, what must an accurate, useful model of an atom
include? - Answer-protons, neutrons, and electrons
Fluorine (Fl), Chlorine (Cl), Bromine (Br), and Iodine (I) are elements in the same group
on the periodic table. Why are these elements grouped together? - Answer-They all
have similar properties.
If egg whites have a pH of 8, what color will it turn litmus paper and how would you
classify it? - Answer-Litmus paper would turn blue and it would be classified as a base.
,If vinegar has a pH of 3, what color would it turn litmus paper and how would it be
classified? - Answer-Litmus paper would turn red and it would be classified as an acid.
What color does litmus paper turn in the presence of an acid? - Answer-red
What color does litmus paper turn in the presence of an base? - Answer-blue
How do we classify a substance with a pH between 1-7? - Answer-acid/acidic
How do we classify a substance with a pH between 7-14? - Answer-base/basic
How do we classify a substance with a pH of exactly 7? - Answer-neutral
If I want to neutralize an acid, what should I add to it? - Answer-a basic solution
Compare pure substances and mixtures. - Answer-Pure substances are either
compounds or elements. Mixtures are homogeneous or heterogeneous combinations.
Define homogeneous mixture - Answer-same composition throughout, like alcohol &
water mixed together
Define heterogeneous mixture - Answer-A mixture that has visibly different parts, like
pizza or salad.
Explain the change that occurs when ice melts. - Answer-Melting is a physical change
and the mass of the substance stays the same.
Define the Law of Conservation of Mass - Answer-mass is neither created nor
destroyed in a chemical reaction, only rearranged
Describe the process of photosynthesis. - Answer-Carbon dioxide and water combine in
the presence of light to form oxygen and glucose.
Describe the process of cellular respiration. - Answer-Glucose and oxygen combine to
produce carbon dioxide, water and energy in the form of ATP.
Who performs photosynthesis? - Answer-plants, algae, and some bacteria
Who performs cellular respiration? - Answer-all living things (both plants and animals)
Where does photosynthesis occur? - Answer-chloroplasts (plant cells)
Where does cellular respiration occur? - Answer-mitochondria
How would placing a plant in a dark room affect the rate of photosynthesis? - Answer-
The rate of photosynthesis would decrease.
, A scientist is investigating the rate of cellular respiration when a person is exercising
and when at rest. How would the amount of gas released be different in these two
situations? - Answer-More carbon dioxide would be released when exercising than
when at rest.
Kendrick goes to his neighborhood gym to exercise. The process of cellular respiration
makes it possible for him to run on the treadmill and to lift weights. What do Kendrick's
cells do during cellular respiration? - Answer-His cells use oxygen to break down food
molecules to release energy.
Carbon is stored in leaves in various forms, such as sugar. When leaves decay, they
lose mass. What happens to the carbon that is stored in leaves when they decay? -
Answer-The carbon is converted into carbon dioxide and released into the atmosphere.
Cellular respiration occurs in the body 24 hours per day. During exercise, the rate of
cellular respiration increases. Why does increased cellular respiration cause people to
breathe faster? - Answer-More oxygen is needed to produce energy, and more carbon
dioxide waste must be removed from the body.
Many athletes use altitude training to improve their performance. They travel to areas of
high altitude where there is less oxygen in the air. The body adapts to the stress of less
oxygen by becoming more efficient at transporting and using
oxygen. What are athletes who train in high altitudes most likely trying to enhance? -
Answer-energy production in the mitochondria
Define herbivore - Answer-eats only plants
Define carnivore - Answer-an animal that feeds on meat
Define omnivore - Answer-An organism that eats both plants and animals
Define commensalism - Answer-relationship between two organisms where one species
benefits and the other is neither harmed nor helped
Define mutualism - Answer-relationship between two organisms where both organisms
benefit
Define parasitism - Answer-relationship between two organisms where one benefits and
one suffers
Define homeostasis - Answer-Maintaining a stable internal environment (ie. sweating
when you're hot and shivering when you're cold)
What change would occur if Earth's rate of rotation significantly increased? - Answer-
The day would be shorter.
