The correct answer is theory: hypothesis. That is, B
Hypothesis refers to a specific and testable prediction. Hypothesis tends to propose what is expected to happen or occur in particular circumstances.
<h2>Further Explanation</h2>
The use of a hypothesis in an experiment is to describe the link or relationship between two variables. In order words, the main purpose of using a hypothesis in an experiment is to determine an answer to a question.
However, the two variables are:
- Independent variable
- Dependent variable
In an experiment, independent variables can be changed and tested, it is the first thing that happens in an experiment and can be regarded as the cause of any changes in the outcome of an experiment, which is referred to as dependent variable
However, a scientific theory refers to a hypothesis about events that are backed up by research using the scientific method. A scientific theory is an explanation of facts about a phenomenon.
Scientific theories have many characteristics, but the five main characteristics that explain how scientific theories work include
- Testable: this implies that theories should be supported through other experiments or scientific research
- Replicable: it means theories must also be carried out or repeated by others. Other scientists should able to replicate the theories to confirm its authenticity
- Stable: the theories must be stable. This implies other should arrive at a similar result when theories are tested.
Other characteristics also include
