Biology Principles Overview

Homeostasis

• The process by which internal environments of organisms remain stable despite external changes.
• Essential for maintaining conditions necessary for life, such as temperature and pH levels.

Interdependence of Nature

• All life forms on Earth are interconnected in various ecosystems.
• Changes in one species can significantly impact others, highlighting the balance of ecosystems.

Evolution

• Describes the gradual changes in groups of organisms over time through processes such as natural selection.
• Leads to the diversity of species seen in the natural world today.

Cellular Basis of Life

• Asserts that all living organisms are composed of cells, which are the basic units of life.
• Cells are responsible for carrying out necessary functions to sustain life.

Information and Heredity

• Genetic information is stored in DNA, which carries universal genetic codes.
• DNA plays a crucial role in inheritance, influencing traits passed from one generation to the next.

Structure and Function

• Different body parts vary in structure according to their specific functions.
• This relationship is evident in anatomy, where form and function align to enhance survival and efficiency.

Matter

• Living organisms require energy and materials, which are derived from their environment.
• Essential nutrients and energy sources are necessary for growth, maintenance, and reproduction.

Science as a Way of Knowing

• Scientific experiments are fundamental in exploring and explaining the natural world.
• Empirical evidence collected through observation and experimentation forms the basis of scientific knowledge.

Growth, Development, and Reproduction

• Organisms not only grow larger but also undergo developmental changes over time.
• Reproduction occurs when individuals produce offspring, ensuring the continuation of species.

Unity and Diversity

• Living organisms exhibit both similarities and variations, highlighting the concept of unity in diversity.
• This reflects shared ancestry among species while embracing the unique adaptations to different environments.
