Flashcards in Chapters 1-3 Deck (121)
the scientific study of life
Properties of life
3. growth and development
4. energy processing
6. response to the environment
7. evolutionary adaptation.
structural and functional unit of life
name species and classify them into broader groups.
Bacteria, Archaea, and Eukarya
Bacteria and Archaea domains
Contain organisms with simple cells
various protists and the kingdoms Fungi, Plantae, and Animalia
result from the specific arrangement and interactions among component parts.
Structural levels of biology
Biosphere -> ecosystem -> community -> population -> organism -> organs and organ system -> tissue -> cell -> organelle -> molecule
is a way of knowing—an approach to understanding the natural world.
involves observations, hypotheses, predictions, tests of hypotheses via experiments or additional observations, and analysis of data.
is broad in scope and supported by a large body of evidence.
The factor that is manipulated in experiment
The measure used to judge the outcome of the experiment
compares an experimental group with a control group.
Endeavor of science
influenced by three spheres:
1. exploration and discovery
2. analysis and feedback from the scientific community
3. societal benefits and outcomes.
Goal of technology
apply scientific knowledge for some specific purpose.
Goal of science
understand natural phenomena.
Unequal reproductive success leads to evolution of adaptations in populations
Selective breeding of plants and animals.
responsible for heredity and for programming the activities of a cell by providing the blueprint for proteins.
through an ecosystem in one direction
1. entering as sunlight
2. converted to chemical energy by producers
3. passed on to consumers
4. exiting as heat.
What are ecosystems characterized by?
the cycling of matter
1. from the atmosphere and soil,
2. through producers, consumers, and decomposers,
3. then back to the environment.
Where scientists attempt to model the behavior of biological systems by analyzing the interactions among their parts
Cell division that results in two daughter cells that have the same number of chromosomes.
When cells kill themselves to prevent over mitotic division
Frequency and duration of specific behaviors. Frequently numerical and measurements.
