_______ rock can be changed directly into _______ rock with the application of heat and pressure.

Final answer:

A book dropped from a certain height has no potential energy when it reaches the floor, since the height (a factor in the potential energy equation 'PE = mgh') becomes zero.

Explanation:

The potential energy of an object of mass (m) at height (h) is given by the formula PE = mgh, where g is the acceleration due to gravity (approximated as 9.8 m/s² on Earth). In this case, however, when a book reaches the floor after being dropped, its height is 0 meters, hence its potential energy is also 0 joules because potential energy is dependent on height.

In the mitochondrion, small molecules combine withoxygen to produce water and carbon-di-oxide. This process releases a large amount of energy.

Explanation:

• The mitochondrial membrane is where the chemical processes happen, and where the fluid contains the matrix.
• It form an integral part of eukaryotic cells. Its principal function is to conduct cellular respiration. This implies that the cell sucks in nutrients, breaks it down and transforms it into energy.
• The oxygen present inside the cell is applied and mitochondria transform chemical energy from food in the cell into energy in a form that is accessible to the host cell, understood as oxidative phosphorylation, it occurs within mitochondria.
• The processes identified as the citric acid or Krebs cycle generate a chemical called NADH in the mitochondria matrix. NADH is then used to produce adenosine triphosphate (ATP) through enzymes located in the inner cone of the mitochondrial membrane.
• Within ATP the energy is contained within chemical bonds form. You can open those bonds and retrieve the energy.

Answer:

Option C:- concentration of products

Explanation:

According to Le Chateleir's principle,

if the forward reaction is favored in the equilibrium then concentration of products will increase and concentration of reactants will decrease.

If the reverse reaction is favored in the equilibrium then concentration of products will decrease and concentration of reactants will increase.

Answer is: adenosine triphosphate.

ATP is made of three components: the triphosphate (P), the sugar ribose and a nitrogenous base (adenine).

ATP is short for adenosine triphosphate

Adenosine triphosphate converts to either the adenosine diphosphate (ADP) or adenosine monophosphate (AMP), in this process energy is released.  

The correct answer is A- Adenosine Triphosphate

Methanol has severl uses few of which are discussed below.

Explanation:

Methanol is the simplest alcohol with chemical formula CH3OH. Its nin drinkable because its toxic when consumed.

Methanol is used for preparing acetaldehyde, formaldehyde, butandiol, acetal resins etc which are used for production of furthur high specific chemicals with high rate of purity. Its also used widely in automobile industry.

Its used to produce acetic acid, solvent esters and acetates, terepthalic acid, etc which are used in automobiles, paint industry, ink industry etc.

Its used in preparation if zero emmision fuels. Its also used to produce antifreeze, lubricants, burning alcohol, spirit etc.

Its also used to produce different cleaners and canned heat.
