Study Notes
Characteristics of Living Things
- Seven essential characteristics define living organisms: Organization, Metabolism, Homeostasis, Growth and Development, Adaptation, Response to Stimuli, and Reproduction.
- Organization: Living organisms consist of cells, organized into tissues, organs, and systems that perform specific functions.
- Metabolism: Refers to all chemical reactions in living organisms that sustain life, including respiration, photosynthesis, and digestion.
- Homeostasis: The ability to maintain a stable internal environment despite external changes, involving temperature regulation, water balance, and pH control.
- Growth and Development: Describes the processes leading to an increase in size and complexity, including cell division, differentiation, and morphogenesis.
- Adaptation: Organisms' ability to adjust to changes in their environment, enabling survival and reproduction.
- Response to Stimuli: The capability to detect and respond to changes in the internal or external environment through sensory perception and behavioral reactions.
- Reproduction: The process by which organisms produce new individuals, either sexually or asexually, ensuring species continuity and genetic information transfer.
Cellular Processes
- Living organisms are exclusively composed of cells, which perform various essential functions.
- A flipbook activity is designed to illustrate how cellular processes work.
Gamete Formation
- Gametes (sperm and egg cells) are formed through meiosis, a specialized cell division that creates haploid cells.
- Meiosis reduces the chromosome number by half through two successive divisions, producing four haploid cells from one diploid cell.
Somatic Cell Replication
- Somatic cells replicate via mitosis, which involves DNA duplication and the division into two genetically identical daughter cells.
- Mitosis is essential for growth, tissue repair, asexual reproduction, maintaining cell populations, wound healing, and immune response.
Oxygen Transfer
- Oxygen transfer from the lungs to the blood occurs through gas exchange in the alveoli.
- Steps involved include ventilation (air inhalation), diffusion (oxygen moving from alveoli to capillaries), and binding with hemoglobin in red blood cells for transport.
Nutritional Considerations
- Focus on recognizing biomolecules and their significance in dietary planning for specific patient conditions.
- Types of patients include those with lactose intolerance, type 2 diabetes, atherosclerosis, osteoporosis, kidney stones, gout, and phenylketonuria (PKU).
Biomolecules
- Carbohydrates: Main energy source for the body, supporting brain, kidney, heart, and muscle function. Fiber aids digestion and maintains blood cholesterol levels.
- Lipids: Insoluble organic compounds (fats, oils, hormones) that serve as energy-storage molecules and chemical messengers.
- Proteins: Building blocks of life, critical for cell repair and new cell creation. They are vital for growth and development, recovery after exercise, and muscle maintenance.
Presentation Preparation
- Teams should prepare presentations about biomolecule importance, focusing on visual organization, clear voice delivery, and individual contributions from all members.
- Use a structured format to design meal plans tailored to individual patient conditions, detailing descriptions, signs/symptoms, treatments, and dietary recommendations.
