Study Notes
Homeostasis
- Refers to the process of maintaining a stable internal environment in living organisms, crucial for proper functioning and survival.
Negative Feedback Mechanism
- A control system that counteracts changes from a set point to bring the system back to its original state.
- Common in biological processes such as temperature regulation and blood sugar control.
Positive Feedback Mechanism
- Enhances changes rather than counteracting them, leading to an amplification of a response.
- While it may destabilize a system initially, it can effectively drive processes like childbirth.
Asexual Reproduction
- Results in offspring that are genetically identical to the parent, preserving traits through clones.
- Examples include binary fission, budding, and vegetative reproduction.
Anabolic Reactions
- Metabolic processes that build up molecules from smaller units, typically consuming energy.
- Examples include protein synthesis and the synthesis of nucleic acids.
Body's Feedback Mechanism
- Utilizes negative feedback to reverse changes and maintain homeostasis, ensuring stability in bodily functions.
Multicellular Organisms
- Living entities composed of multiple cells, allowing for greater complexity in structure and function.
- Examples include plants, animals, and fungi.
Material Intake for Energy
- The term for the process of taking in materials, such as nutrients and oxygen, for energy is ingestion.
- Essential for growth, repair, and maintenance of cellular functions.
