Biology Fundamentals Quiz

Unifying Theme of Life

• Evolution through natural selection is the unifying theme explaining the unity and diversity of life.
• It showcases how species adapt over time while retaining common characteristics.

Cellular Component for Hereditary Information

• DNA (deoxyribonucleic acid) is the cellular component that processes hereditary information encoded in genes.
• Genes are segments of DNA that provide instructions for building proteins, crucial for organismal function.

Mechanisms of Movement, Growth, and Reproduction

• Cellular structures and processes like muscle fibers, cytoskeleton, and energy production in mitochondria enable organisms to move, grow, and reproduce.
• Metabolism, including catabolic and anabolic reactions, provides the necessary energy and building blocks.

Levels of Biological Organization

• Biologists study life at multiple levels, including:
  • Molecular level: DNA and proteins.
  • Cellular level: Single cells and tissues.
  • Organismal level: Individual organisms.
  • Population level: Groups of the same species.
  • Ecosystem level: Interactions between different species and their environments.

Tools for Observation and Inquiry

• Biologists use various tools for observations, including microscopes, field studies, and technology such as DNA sequencing.
• These tools help in posing questions and generating hypotheses for further research.
