Biology
Biology is the study of living organisms and their interactions with each other and their environment. It is a fascinating field that encompasses a wide range of topics, from the molecular mechanisms of cells to the behavior of entire ecosystems.
Key Concepts in Biology
- Cell Theory: All living organisms are composed of cells, and all cells come from pre-existing cells.
- Genetics: The study of genes and heredity, including DNA, inheritance, and genetic variation.
- Ecology: The study of the relationships between organisms and their environment, including topics such as populations, communities, and ecosystems.
- Evolution: The process of biological change over time, leading to the diversity of life on Earth.
- Anatomy and Physiology: The structure and function of living organisms, including organs, tissues, and organ systems.
Study Tips
- Take detailed notes during class and review them regularly.
- Use visual aids, such as diagrams and charts, to help understand complex biological processes.
- Practice active learning by discussing concepts with classmates or teaching them to someone else.
- Utilize online resources, such as interactive simulations and educational videos, to reinforce your understanding of biological concepts.
- Prepare for exams by quizzing yourself and solving practice problems.

LIFE SCIENCE
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
