Empirical evidence is information acquired by observation or experimentation. Scientists record and analyze this data. The process is a central part of the scientific method

Muscle cells access what they need to continue producing energy through chemical energy from ATP to transform it into mechanical energy.
Muscle cells are elongated cells whose length can reach several centimeters.
The muscle uses ATP (energy) to carry out conformational changes in its molecular structure => variation in the length of the sarcomere.
Adenosine triphosphate (ATP) is the basic source of energy for muscle contraction.
Each link stores 7300 calories of energy per mole of ATP under normal conditions and when a phosphate radical is separated from the molecule, these calories are available providing the energy necessary for muscle contraction.
The muscle cell has three mechanisms to resynthesize ATP:
- ATP synthesis through phosphocreatine.
- Anaerobic glycolysis process with the transformation of muscle glycogen into lactate.
- From oxidative phosphorylation.
ATP synthesis through phosphocreatine consists of the transfer of energy from phosphocreatine to ADP so that it can reincorporate a phosphate group to its molecule and transform it into ATP.
So the energy that has been released in the hydrolysis of PCr is directly used to resynthesize ATP from ADP.
Therefore, we can conclude that muscle cells access what they need to continue producing energy through the chemical energy of ATP to transform it into mechanical energy.

All of the above statements describes scientific theory
Answer: Option D
<u>Explanation:</u>
A scientific theory is a clarification of a part of the characteristic world that can be more than once tried and confirmed as per the logical strategy, utilizing acknowledged conventions of perception, estimation, and assessment of results. Where potential, hypotheses are tried under controlled conditions in an examination.
In conditions not amiable to trial testing, speculations are assessed through standards of deductive thinking. Set up logical speculations have withstood thorough examination and epitomize logical information. The importance of the term scientific theory as utilized in the control science that is altogether unique in relation to the basic vernacular utilization of theory.
In ordinary discourse, the hypothesis can suggest a clarification that speaks to an unconfirmed and theoretical guess, while in science it depicts a clarification that has been tried and broadly acknowledged as substantial. These various utilization are practically identical to the contradicting uses of forecast in science versus basic discourse, where it signifies a simple expectation.
