Study Notes
Animal Structure
- Animals are composed of specialized cells
- Cells combine to form tissues
- Tissues combine to form organs
- Organs work together in systems to perform body functions
- Examples of animal systems include the digestive and nervous systems
Chemical Reactions and Health Hazards
- Chemical reactions occur when chemicals interact predictably
- Examples include mixing baking soda and vinegar
- Chemical reactions are crucial in producing products like food, medicine, and cleaning supplies
- Chemicals, while useful, can be hazardous if misused
- Some chemicals are harmful or toxic to humans and animals
Climate Change
- Global climate change involves long-term shifts in Earth's temperature and weather patterns
- Natural factors and human activities (especially burning fossil fuels) contribute to climate change
- Burning fossil fuels releases gases that trap heat in the atmosphere
- Global climate change impacts natural systems (e.g., oceans, forests) and living organisms
- Examples of impacts include melting ice caps/glaciers raising sea levels and affecting animal habitats and plant growth.
