Biology for AP® Courses - Chapter 1 - The Study of Life

Carl Woese

Established a separate domain for Archaea using sequences of rRNA.

Smaller leaves

Benefit desert plants by reducing water loss through evaporation.

Biological organization order

Hydrogen atom, water molecule, skin cell, liver, elephant, wolf pack, tropical rainforest, planet Earth.

Testable explanation

A hypothesis.

Deductive reasoning inference

All living organisms share a common origin due to the presence of mitochondria.

Genetic material in viruses

Viruses can possess both DNA and RNA.

True statement about viruses

Viruses must rely on a host to survive.

Population

A group of individuals of the same species living in a specific area.

Peer review process

Involves experts reviewing scientific papers to ensure quality and originality.

Hierarchy of biological organization

Biosphere, ecosystem, community, population, organism.

Natural science exclusion

Computer science is NOT considered a natural science.

Eukaryotic vs

Eukaryotic cells contain a membrane-bound nucleus.

Mathematics in natural science

It is not considered a natural science as it emphasizes mathematical concepts rather than the natural world.

Scientific research process

Peer review checks for originality and quality before publication.

Scientific method application

It allows for testing hypotheses through controlled observations in experiments.

Measurable hypothesis significance

Enables objective evaluation of results.

Viruses classification

Classified as non-living entities because they require a host to replicate.

Biological organization level

The biosphere includes all living organisms on Earth.

Population interactions

Occur through competition, predation, and symbiosis within an ecosystem.

Adaptations in polluted environments

Help organisms survive by improving resource use efficiency.

Community definition

Includes all living organisms in a specific area.

Experimental data verification

Can be done through statistical analysis and modeling.

Virus characteristics

Not made of cells, lack metabolic machinery, and cannot reproduce independently.

Importance of studying diseases

Helps understand disease mechanisms, develop treatments, and improve public health.

Hypothesis importance

Provides a basis for experimentation and predictions in the scientific method.
