4 Key Terms

opening section of a scientific paper that summarizes the research and conclusions
applied science
form of science that aims to solve real-world problems
smallest and most fundamental unit of matter that retains the properties of an element
basic science
science that seeks to expand knowledge and understanding regardless of the short-term application of that knowledge
study of the chemistry of biological organisms
the study of life
collection of all the ecosystems on Earth
study of plants
smallest fundamental unit of structure and function in living things
set of populations inhabiting a particular area
section of a scientific paper that summarizes the importance of the experimental findings
part of an experiment that does not change during the experiment
deductive reasoning
form of logical thinking that uses a general inclusive statement to predict specific results
dependent variable
the possible outcome of the experiment; the effect
descriptive science
(also, discovery science) form of science that aims to observe, explore, and investigate
section of a scientific paper in which the author interprets experimental results, describes how variables may be related, and attempts to explain the phenomenon in question
all the living things in a particular area together with the abiotic, nonliving parts of that environment
organism with cells that have nuclei and membrane-bound organelles
the process of gradual change in a population or species over time
able to be disproven by experimental results
ability of an organism to maintain constant internal conditions
suggested explanation for an observation, which one can test
hypothesis-based science
form of science that begins with a specific question and potential testable answers
independent variable
what you have control over; what you can choose and manipulate
inductive reasoning
form of logical thinking that uses related observations to arrive at a general conclusion
opening section of a scientific paper, which provides background information about what was known in the field prior to the research reported in the paper
life science
field of science, such as biology, that studies living things
large molecule, typically formed by the joining of smaller molecules
materials and methods
section of a scientific paper that includes a complete description of the substances, methods, and techniques that the researchers used to gather data
study of the structure and function of microorganisms
molecular biology
study of biological processes and their regulation at the molecular level, including interactions among molecules such as DNA, RNA, and proteins
chemical structure consisting of at least two atoms held together by one or more chemical bonds
natural science
field of science that is related to the physical world and its phenomena and processes
study of the biology of the nervous system
collection of related tissues grouped together performing a common function
organ system
level of organization that consists of functionally related interacting organs
small structures that exist within cells and carry out cellular functions
individual living entity
study of life’s history by means of fossils
peer-reviewed manuscript
scientific paper that a scientist’s colleagues review who are experts in the field of study
phylogenetic tree
diagram showing the evolutionary relationships among various biological species based on similarities and differences in genetic or physical traits or both; in essence, a hypothesis concerning evolutionary connections
physical science
field of science, such as geology, astronomy, physics, and chemistry, that studies nonliving matter
using other people’s work or ideas without proper citation, creating the false impression that those are the author’s original ideas
all of the individuals of a species living within a specific area
single-celled organism that lacks organelles and does not have nuclei surrounded by a nuclear membrane
section of a scientific paper in which the author narrates the experimental findings and presents relevant figures, pictures, diagrams, graphs, and tables, without any further interpretation
review article
paper that summarizes and comments on findings that were published as primary literature
knowledge that covers general truths or the operation of general laws, especially when acquired and tested by the scientific method
scientific method
method of research with defined steps that include observation, formulation of a hypothesis, testing, and confirming or falsifying the hypothesis
fortunate accident or a lucky surprise
tested and confirmed explanation for observations or phenomena
group of similar cells carrying out related functions
part of an experiment that the experimenter can vary or change
study of animals
