Scientific Method: Core Concepts of Biology Flashcards
The region of the Earth’s surface where all organisms are found is called the
Biosphere
All of the chemical reactions that occur in a cell are called
Metabolism
A modification that helps equip organisms for their way of life is a(n)
Adaption
The process of turning solar energy into chemical energy is called
Photosynthesis
Place the steps in the process of natural selection in the correct order:
1) over generations, a larger proportion of the population becomes adapted to the environment.
2) The population produces more offspring than the environment can support.
3) Members of a population have heritable variations.
4) The more adapted individuals survive and reproduce to a greater extent than those individuals lacking adaptions.
3,2,4,1
Adaption
Modifications that make organisms suited to their way of life
Binomial name
A two part scientific name
Biodiversity
Variation in life on earth, and it usually refers to the number of different species.
Multicellular
Plants, fungi, and animals are multicellular. Many types of cells.
Energy
Capacity to do work
Metabolism
Chemical reactions that occur in a cell
Photosynthesis
Transforms solar energy into the chemical energy of nutrient molecules
Homeostasis
Maintenance of internal conditions within certain boundaries.
Adaptions
Modifications that make organisms suited to their way of life
Evolution
Process by which species have changed and diversified since life first arose
Taxonomy
Discipline of identifying and naming organisms
Systematics
Classifying organisms according to their presumed evolutionary relationships
Biosphere
The zone of air, land, and water where living organisms are found
Population
All members of a species within a particular area
Community
The population within a community interacts among themselves and with the physical environment (soil,atmosphere, ect.)
Ecosystem
Biosphere, population, and community combined together.
Observation
First step in scientific method
Inductive reasoning
When a person uses creative thinking to combine isolated facts into a cohesive whole.
Hypothesis
Based on existing knowledge, so it is much more informed than a mere guess
Experiment
Series of procedures to test a specific hypothesis
Experimental design
The manner in which a scientist intends to conduct an experiment
Experimental variable
Deliberately changed in experiment while other factors are kept constant
Test groups
Exposed to experimental variable
Control group
Is not exposed to experimental variable
Data
Results of experiment
Conclusion
Whether a hypothesis is supported or not by reviewing data
Scientific theories
Accepted explanations of how the world works
Bioethics
The branch of ethics that is concerned with the development and consequences of biological technology
Extinction
The death of a species
A group of interbreeding individuals is a(n)
Species
Information collected from a scientific experiment is known as
Data
Taxonomy is a biological discipline in which organisms are grouped according to their
Common ancestries
A representation of a natural phenomenon studied by scientists when the real object is impossible to study is a(n)
Model
A hypothesis cannot be formed without
Observation
