A biology teacher asks his class to make models of a plant cell, an animal cell, and a
bacterial cell. Aside from cytoplasm and the cell membrane, which other cell structure
will the students need to make for all three models? - ANSWER-ribosome
A specimen has a cell wall & ribosomes present but lacks a nuclear membrane then it is
a - ANSWER-prokaryote
A specimen has a cell wall, ribosomes, large vacuole and nucleus present then it is a -
ANSWER-plant
C6H6 represents a/an - ANSWER-organic compound
DNA is the genetic material that makes up living things, and folic acid plays an
important role in the formation of DNA. Jon wants to study the effect of folic acid on
DNA formation in microbes. Which statement accurately describe the variables in this
study? - ANSWER-The amount of folic acid is the independent variable, and the DNA
synthesized is the dependent variable.
Essential amino acids cannot be produced by the body, so they must come from our
diet. We can get them from eating foods that contain which biomolecule? - ANSWER-
protein
If a scientist tested: the measure of cholesterol levels in exercisers and non-exercisers.
The cholesterol levels would be a _____ variable - ANSWER-dependent
Iron reacts with atmospheric oxygen to form iron oxide or ferric oxide. Look at the
chemical equation for this reaction:
Fe + O2 → Fe2O3
This equation is unbalanced. What is the correct balanced equation for this reaction? -
ANSWER-4Fe + 3O2 → 2Fe2O3
SO2 is an example of a/an - ANSWER-inorganic compound
The chemical symbol K represents a/ an - ANSWER-element
The function of mitochondria and chloroplasts is related to energy. In what way does
their function differ? - ANSWER-Mitochondria produce energy from food, while
chloroplasts produce food from the Sun's energy.
The statement; people who exercise for an hour may have lower cholesterol levels is a -
