What does the scientific term for theory mean?
A theory is a
carefully thought-out explanation for observations of the natural world
that has been constructed using the scientific method, and which brings together many facts and hypotheses. … A scientist makes an observation of a natural phenomenon.
How does a scientific explanation become widely accepted?
A scientific theory is a broad explanation that is widely accepted
because it is supported by a great deal of evidence
. Examples of theories in physical science include Dalton’s atomic theory, Einstein’s theory of gravity, and the kinetic theory of matter.
What is a scientific theory that is currently accepted as true?
A scientific theory is accepted as
a scientific truth
, supported by evidence collected by many scientists. The theory of evolution by natural selection is a classic scientific theory.
Why is the cell theory called a theory and not a fact?
Cell theory is a theory, not a law
because the cell theory does not have enough support to become a law
. … All cells come from pre-existing cells, and that is the basic unit reproduction and a basic unit of all organisms.
What best describes a scientific theory?
A scientific theory is
a well-tested, broad explanation of a natural phenomenon
. In everyday life, we often use the word theory to mean a hypothesis or educated guess, but a theory in the context of science is not simply a guess—it is an explanation based on extensive and repeated experimentation.
What makes a theory a good theory?
What makes a theory useful? … One lesson is that the reason a “good” theory
should be testable, be coherent, be economical, be generalizable
, and explain known findings is that all of these characteristics serve the primary function of a theory–to be generative of new ideas and new discoveries.
What is a well tested and widely accepted explanation for a phenomenon?
SCIENTIFIC THEORY
. A well-tested explanation accepted by scientists that unifies a broad range of observations and hypotheses; a well-supported and widely accepted explanation of natural phenomena. SCIENTIFIC LAW.
Why are scientific theories an important part of research and understanding?
Why are scientific theories an important part of research and understanding? Scientific theories
allow scientists to make predictions
. … It helps to predict outcomes and define the parameters of the research. True or False: Scientific theories are always broad and cover many concepts.
Why is scientific theory important?
A theory not
only explains known facts
; it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable. New evidence should be compatible with a theory.
What is an explanation for widely accepted events?
Overview.
A scientific theory
is a broad explanation for events that is widely accepted as true. To become a theory, a hypothesis must be tested over and over again, and it must be supported by a great deal of evidence.
Why is the cell theory considered a scientific theory quizlet?
The cell theory states that the cell is the most basic unit of life, all organisms are made of cells, and all cells come from cells. What makes the cell theory a scientific theory?
It is based on the work of many scientists and leads to accurate predictions
.
What is widely accepted theory?
The most widely accepted explanation is
the big bang theory
. Learn about the explosion that started it all and how the universe grew from the size of an atom to encompass everything in existence today.
How does the cell theory demonstrate this definition of theory?
The cell theory demonstrates the scientific definition of a theory in three ways. First it has been tested extensively. Second,
it summarizes the research and observations of many different scientists who worked at different times
. … The nucleus of a cell is found in the cytoplasm, but is not part of the cytoplasm.
Why is cell theory important to science and society?
Cell theory – This is crucial for us
understanding biology because cells form the basis of all life
. … [And] cell division, the division of a cell from one, to two, to four, forms the basis of growth and development of all living things. When it goes wrong, as in cancer, then of course it’s crucial for disease.
What differentiates a scientific theory from a scientific hypothesis?
In scientific reasoning, a hypothesis is
an assumption made before any research has been completed for the sake of testing
. A theory on the other hand is a principle set to explain phenomena already supported by data. … And that’s where we see the difference between a hypothesis and a theory.
Which of the following best describes when a hypothesis becomes a scientific theory?
A hypothesis becomes a theory
when it has been confirmed by a single experiment
. A hypothesis must be testable and can be disproven, whereas a theory is testable but cannot be disproven.
What is a scientific idea that is well tested and widely accepted by the scientific community?
A well-tested and widely accepted scientific hypothesis or a group of related hypotheses is called
a scientific theory
.
What is meant by good theory?
A good theory
describes, explains, and has considerable prognostic value
. With a minimum number of assumptions a stupendous number of results can be derived and understood. But more than that it rather straightforwardly leads to amazing technique and remarkable applications.
What is the meaning of good theory?
Good theory is
accurate, useful, explanatory, evidence-based, falsifiable, broadly applicable and consistent
(within itself and with other accepted theories). It’s also what we think social commerce needs.
What is the widely accepted explanation of the relationship between cells and living things called?
The observations of Hooke, Leeuwenhoek, Schleiden, Schwann, Virchow, and others led to the development of
the cell theory
. The cell theory is a widely accepted explanation of the relationship between cells and living things. The cell theory states: All living things or organisms are made of cells and their products.
What is a widely accepted rule that reliably predicts natural events under any testable condition?
observation
.
theory
.
law
. data. Which word means: a widely accepted rule that reliably predicts natural events under any testable condition.
What is theory and why is it important?
Why theory is important
1.
Theory provides concepts to name what we observe and to explain relationships between concepts
. Theory allows us to explain what we see and to figure out how to bring about change. Theory is a tool that enables us to identify a problem and to plan a means for altering the situation.
How does a unicellular organism compare to a multicellular organism?
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use
many different cells to function
. … Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.
Who gave cell theory describe cell theory?
The classical cell theory was proposed by
Theodor Schwann
in 1839. There are three parts to this theory. The first part states that all organisms are made of cells.
What is cell theory briefly describe the essential features of a prokaryotic cell?
Prokaryotic cells lack a nucleus surrounded by a complex nuclear membrane and generally have a single, circular chromosome located in a nucleoid
. Eukaryotic cells have a nucleus surrounded by a complex nuclear membrane that contains multiple, rod-shaped chromosomes. All plant cells and animal cells are eukaryotic.
What does the development of the cell theory show us about the nature of science?
This paved the way for modern cellular science. Three scientists are credited with the development of cell theory. Matthias
Schleiden observed that all plants were made of cells
; Theodor Schwann observed that all animals were also made of cells; and Rudolf Virchow observed that cells only come from other cells.
