- Ecology and Environmental Science
Cell Structure and Function
Cells are the basic units of life. They are responsible for all the functions that living organisms perform. Here are some key points to understand about cell structure and function:
- Cell Membrane: The cell membrane is a selectively permeable barrier that separates the cell from its environment.
- Cytoplasm: The cytoplasm is a jelly-like substance that fills the cell and contains various organelles.
- Nucleus: The nucleus contains the cell's genetic material and is responsible for controlling cell activities.
Molecular Biology
Molecular biology is the study of biological molecules and their interactions. It plays a crucial role in understanding various biological processes.
- DNA: DNA is the genetic material that carries the instructions for building and maintaining an organism.
- RNA: RNA is involved in protein synthesis and gene expression.
- Proteins: Proteins are essential for cell structure, function, and regulation.
Human Body Systems
The human body is composed of various systems that work together to maintain homeostasis and perform different functions.
- Cardiovascular System: Responsible for transporting blood, oxygen, and nutrients throughout the body.
- Digestive System: Breaks down food into nutrients that can be absorbed by the body.
- Respiratory System: Allows oxygen to enter the body and carbon dioxide to be removed.
Ecology and Environmental Science
Ecology is the study of interactions between organisms and their environment. Environmental science focuses on the impact of human activities on the environment.
- Biodiversity: The variety of life on Earth is essential for maintaining ecological balance.
- Climate Change: Human activities have led to significant changes in the Earth's climate, affecting ecosystems and biodiversity.
- Sustainable Development: Finding a balance between meeting present needs and preserving resources for future generations.
