Cellular clock theory believes that our cells regenerate a finite number of times (commonly believed to be 75-80). Free-radical theory believes that oxidized molecules (free radicals) attack healthy cells. Both are cell related and both very likely play a role.

What is the difference between theory and model in the context of scientific research?

In scientific research, a theory is a well-established explanation for a phenomenon based on evidence and tested hypotheses. A model, on the other hand, is a simplified representation of a system or process used to make predictions or understand complex concepts. The main difference is that a theory explains why something happens, while a model helps visualize or simulate how it happens.


What is the difference between caloric and kinetic theories?

The difference between caloric and kinetic theories is that:Caloric theory assumes that heat travels from one object to another by means of fluids.Kinetic theories assumes that heat is generated by the microscopic motion of atoms and molecules inside an object.


What is the difference between a scientific theory and a scientific law?

A scientific theory is an explanation supported by evidence and can be modified as new evidence is discovered. A scientific law is a description of a natural phenomenon that is consistent and often expressed mathematically, without explaining why it happens.


What is the difference between particle and wave theory of light?

Particle theory of light, proposed by Isaac Newton, views light as composed of discrete particles called photons. Wave theory of light, formulated by Thomas Young, describes light as a wave propagating through a medium. The wave theory better explains phenomena like interference and diffraction, while the particle theory accounts for aspects such as the photoelectric effect.


What is the difference between Newtonian gravity and Einstein's theory of gravity?

Newtonian gravity is based on the concept of gravitational force acting between two objects with mass, according to an inverse square law. Einstein's theory of gravity, known as general relativity, describes gravity as the curvature of spacetime caused by mass and energy. This theory provides a more accurate explanation of gravitational phenomena, especially in extreme conditions such as near massive objects or at high speeds.

What is the main difference between the heliocentric theory in the geocentric theory?

The main difference - is the centre of the galaxy. The heliocentric theory placed the Sun at the centre of our galaxy - the previous 'geocentric' theory placed the Earth at the centre.
