Study Notes
Water Molecules and Interactions
- Water molecules interact with each other via hydrogen bonds.
Water Adhesion
- Adhesion of water molecules explains capillary action in soil.
Water as a Solvent
- Water is a hydrophilic/polar solvent.
Water Buoyancy vs Viscosity
- Water has relatively high buoyancy compared to air.
Nucleotide Structure
- The circle in a nucleotide structure is a phosphate group.
- The pentagon in a nucleotide structure is deoxyribose (a five-carbon sugar).
Nucleic Acid Identification
- ATP is not a nucleic acid.
Complementary Base Pairs in DNA
- Adenine is complementary to thymine in DNA.
Biological Species Concept
- Different species within the same genus like Canis lupus and Canis familiaris may have different morphologies.
- These species may not be able to produce fertile offspring.
Types of Cells
- Prokaryotic cells: lack a nucleus.
- Eukaryotic cells: contain a nucleus.
Electron Microscopy Techniques
- Freeze fracture techniques and fluorescent stain usage are used in modern electron microscopy.
Organelles
- Chloroplasts are not typically found in animal cells.
Variation in Humans
- Discontinuous variations like blood type are considered a distinct example.
Chromosomes and Cell Division
- A cell with half the typical number of chromosomes is considered haploid.
