Question

which of the following is an example of a scientific theory? inertia: an object will not change its motion unless acted upon by an unbalanced force. cell arise from other cells. if a paramecium is placed in a hypotonic solution, then the contractile vacuole activity will increase. water boils at 100°c at sea level.

Explanation:

A scientific theory is a well - substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.

• The statement "Inertia: An object will not change its motion unless acted upon by an unbalanced force" is Newton's first law, which is a scientific law, not a theory. A scientific law describes a phenomenon.
• "Cell arise from other cells" is part of the cell theory, which is a scientific theory as it explains the origin of cells based on extensive evidence.
• "If a paramecium is placed in a hypotonic solution, then the contractile vacuole activity will increase" is a hypothesis or a prediction about a specific experiment, not a theory.
• "Water boils at 100°C at sea level" is a scientific fact or a description of a physical phenomenon at a specific condition, not a theory.

Answer:

The option "Cell arise from other cells" (the second option among the given choices)
