In the scientific method, scientific theories. must be tested and verified by observations. b.must be verified by the leading authorities in the field. c. must be consistent with previous, universally accepted scientific concepts. d. must be consistent with the fact that the ocean is of great age. e. are accepted as absolute fact until proven otherwise.

must be tested and verified by observations.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

A scientific method can be defined as a research method that typically involves the use of experimental and mathematical techniques which comprises of a series of steps such as systematic observation, measurement, and analysis to formulate, test and modify a hypothesis.

In the scientific method, scientific theories must be tested and verified by observations.

This ultimately implies that, all scientific theories must be testable, consistently verifiable and supported by observations or experiments.

An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).

This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

but there is no

i guess you forgot putting it.
