What is the primary focus of BIO 101?

BIO 101 focuses on cell structures, functions, and the characteristics of living organisms, including reproduction, heredity, and evolution.

What are the characteristics common to all living organisms?

Living organisms are composed of cells, require energy, grow, develop, reproduce, maintain homeostasis, are interdependent, and evolve.

How do living things maintain internal stability?

Living things maintain internal stability through homeostasis, regulating conditions like temperature and pH to sustain life processes.

What is the role of DNA in reproduction?

DNA contains the instructions for growth and development, ensuring offspring inherit characteristics from their parents.

Define 'ecosystem' in biological terms.

An ecosystem consists of all living things in a particular area, interacting with each other and their non-living environment.

What is the difference between prokaryotic and eukaryotic cells?

Prokaryotic cells lack membrane-bound nuclei and organelles, while eukaryotic cells have these structures.

What is the significance of adaptations in evolution?

Adaptations enhance an organism's ability to survive and reproduce in its environment, driven by natural selection.

How do organisms obtain energy?

Organisms obtain energy either by capturing sunlight (photosynthesis) or consuming other organisms (heterotrophy).

What is the hierarchy of biological organization from smallest to largest?

The hierarchy is: atom, molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere.

Why is biology important in addressing global challenges?

Biology helps understand and solve issues like disease, food security, and environmental changes, impacting health and sustainability.
