Carolina Wilmington – Full Study Guide with
Questions and Answers
1. What are the two structural forms that monosaccharides like glucose can
take?
branched and straight
single and double
solid and liquid
linear and ring
2. What do most genes encode that is crucial for protein production?
DNA
mRNAs
rRNA
tRNA
3. Describe the significance of primitive cells in the context of the evolution
of life on Earth.
Primitive cells are a type of organelle found in complex cells.
Primitive cells are significant as they represent the earliest
forms of life, from which more complex organisms evolved.
Primitive cells are the most advanced forms of life on Earth.
Primitive cells are responsible for the development of
, multicellular organisms.
4. Which organelle contains acid hydrolases?
Lysosomes
, Ribosomes
Mitochondria
Endoplasmic Reticulum
5. If a scientist were to conduct an experiment similar to Rutherford's gold
foil experiment, what key observation would they expect to make
regarding atomic structure?
All alpha particles would be deflected at sharp angles,
suggesting a solid structure.
Alpha particles would be absorbed by the foil, indicating a dense
atomic structure.
Most of the alpha particles would pass through the foil,
indicating that atoms are mostly empty space.
Some alpha particles would bounce back, revealing the presence
of electrons.
6. What is the definition of an isotonic solution?
When the solution inside the cell is more concentrated than
outside
When the solution outside the cell is more concentrated than
inside
When there is no movement of water across the cell membrane
When solution levels are equal inside and outside of the cell
7. What is the primary structural difference between the cytoplasm of
bacterial cells and eukaryotic cells?
Both types of cells have a single compartment in their cytoplasm.
Eukaryotic cells have multiple compartments in their cytoplasm.
