Biological characteristics refer to the physical attributes and traits that are determined by an individual's genetic makeup and biological processes. These characteristics can include things like height, weight, hair color, eye color, skin tone, blood type, and genetic predispositions to certain diseases or conditions. Biological characteristics are inherited from parents and are unique to each individual.

Biological Characteristics
1. Cellular Structure:
- Prokaryotes: Lack a nuclear envelope and organelles, e.g., bacteria
- Eukaryotes: Have a nuclear envelope and membrane-bound organelles, e.g., plants, animals, fungi, protists
2. Genome:
- DNA (deoxyribonucleic acid): Hereditary material
- Chromosomes: Organized DNA molecules
- Genes: Segments of DNA coding for specific traits
3. Metabolism:
- Energy generation: Catabolism and anabolism
- Nutrient utilization: Heterotrophs (ingest organic matter) vs. autotrophs (photosynthesis or chemosynthesis)
- Cellular respiration: Mitochondrial (aerobic) or glycolytic (anaerobic)
4. Reproduction:
- Asexual reproduction: One parent, identical offspring
- Sexual reproduction: Two parents, genetically diverse offspring
- Mitosis: Cell division resulting in genetically identical daughter cells
- Meiosis: Cell division resulting in gametes (sex cells)
5. Growth and Development:
- Cell division, cell growth, and tissue differentiation
- Hormones: Chemical messengers involved in growth and development
6. Response to Stimuli:
- Irritability: Ability to respond to changes in the external environment
- Tropisms: Growth responses to specific stimuli, e.g., phototropism (toward light)
- Taxis: Movement responses to specific stimuli, e.g., chemotaxis (toward chemicals)
7. Homeostasis:
- Maintenance of a stable internal environment
- Regulation of body temperature, pH, ion concentrations, etc.
- Feedback mechanisms: Processes that sense and respond to changes in the internal environment
8. Evolution:
- Genetic variation, natural selection, adaptation
- Changes in the genetic makeup of a population over time
- Speciation: Formation of new species
