EXAM QUESTIONS AND CORRECT DETAILED ANSWERS
(VERIFIED ANSWERS) GRADED A+ (MOST RECENT!!)
Which chamber of the heart pumps blood out of the heart into the
circulatory system? - ANSWER -The left ventricle.
The left ventricle pumps blood into the circulatory system via the aorta.
Where are vacuoles found? - ANSWER -Inside plant and animal cells.
Vacuoles are organelles used for storage and/or maintaining cell pH and
pressure.
What do ribosomes do? - ANSWER -Build proteins from amino acids
Ribosomes are molecules which create proteins by linking amino acids
together in a particular order, using messenger RNA molecules as a
blueprint.
What is the name of the organelle(s) where photosynthesis takes place? -
ANSWER -Chloroplasts
Chloroplasts are found in plant cells and contain chlorophyll which
converts the energy from sunlight into sugars.
What is mitosis? - ANSWER -The division of a cell nucleus.
pg. 1
,2|Page
During mitosis, a cell nucleus divides, producing two identical sets of
chromosomes.
Name the four primary nucleobases found in DNA - ANSWER -cytosine
(C), guanine (G), adenine (A), and thymine (T)
If a genotype consists of two identical alleles, is it homozygous or
heterozygous? - ANSWER -homozygous
A relationship between two organisms which is of benefit to both, is
what kind of symbiosis? - ANSWER -Mutualism.
e.g. the relationship between clownfish and sea anemones - the
clownfish clean and feed the sea anemones, while the sea anemones
protect the clownfish from predators.
In taxonomy, which ranking is most inclusive, Kingdom or Genus? -
ANSWER -Kingdom
Kingdom is the second highest rank, containing Animalia, Plantae,
Fungi, Protista, Archaea and Bacteria. Genus comes below Family and
above Species.
Casein, found in milk and consisting of amino acids, is what kind of
molecule? - ANSWER -Protein
pg. 2

Prokaryotes reproduce through which mechanism? - ANSWER -Binary
fission.
This is a form of asexual reproduction, where a parent cell divides into
two identical daughter cells.
What is the final stage of mitosis? - ANSWER -Telophase.
During telophase, the duplicated genetic material in a parent cell is split
into two identical daughter cells.
Define sublimation - ANSWER -It's the change of state directly from
solid to gas.
What process produces lactic acid in muscles? - ANSWER -
Fermentation.
During fermentation, glucose is converted to lactic acid.
What is active transport and where does it occur? - ANSWER -The
movement of molecules from an area of lower concentration to an area
of higher concentration. It occurs across cell membranes.
What is cytoplasm? - ANSWER -The thick fluid that fills cells
What are the four fundamental states of matter? - ANSWER -Solid,
liquid, gas and plasma
pg. 3
, 4|Page
How many times more basic is pH 10 compared to pH 8? - ANSWER -
100
The pH scale is logarithmic with a basis of 10, so each unit difference
corresponds to a factor of 10.
During the process of oxidation, are electrons lost or gained? -
ANSWER -Lost.
Oxidation is the loss of electrons and reduction is the gain of electrons.
Do all isotopes of a particular element have the same number of protons
or the same number of neutrons? - ANSWER -protons.
The number of neutrons varies, but the number of protons is always the
same.
Define the half-life of radioactive material. - ANSWER -The time it
takes for half of the nuclei to decay.
Which type of chemical bond involves the sharing of electrons between
atoms? - ANSWER -covalent.
Covalent bonding typically occurs between two atoms of the same
element or between atoms that are close to each other on the periodic
table.
What is produced when a metal oxide is mixed with an acid? -
ANSWER -A salt and water
