How is body temperature regulation an example of negative feedback?
Body temperature regulation involves mechanisms that counteract deviations from a set point, maintaining homeostasis.
What are 3-4 examples of internal factors that are kept constant in animals?
- Temperature
- pH levels
- Blood glucose levels
- Electrolyte balance
What is homeostasis?
Homeostasis is the process by which biological systems maintain stability while adjusting to conditions that are optimal for survival.
Which systems are particularly helpful for maintaining homeostasis in animals?
The nervous and endocrine systems.
How are animals structurally adapted to enhance exchange between their bodies and their environment?
Animals have adaptations such as increased surface area, specialized structures (like lungs or gills), and transport systems (like circulatory systems).
What is a tissue?
A tissue is a group of cells that work together to perform a specific function.
What is an organ?
An organ is a structure composed of two or more types of tissues that work together to perform specific functions.
What is an organ system?
An organ system is a group of organs that work together to carry out complex functions necessary for life.
What are the levels of organization in biological systems?
The levels of organization are: cell → tissue → organ → organ system.
