UNCW BIO 201 Exam 1 | University of North Carolina Wilmington – Full Study Guide with Questions and Answers
- What are the two structural forms that monosaccharides like glucose can
take?
branched and straight single and double solid and liquid linear and ring
- What do most genes encode that is crucial for protein production?
DNA mRNAs rRNA tRNA
- 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 1 / 3
multicellular organisms.
- Which organelle contains acid hydrolases?
Lysosomes 2 / 3
Ribosomes Mitochondria Endoplasmic Reticulum
- 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.
- 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
- 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.
