Transparency (also called pellucidity or diaphaneity) in the field of optics is the physical property of allowing light to pass through the material without significant light dispersion.
Glycolysis yields 2 ATP molecules, Krebs cycle yields 2 ATP molecules, ETS yields 34 ATP molecules.
"A" is the answer. The chemical reaction is when the batter becomes brown.
B is mixing C is mass becoming a liquid and D. is dissolving no chemical reaction happened there.
Hope that helps!
Mass spectrometry was discovered by Francis Aston, a British Physicist, in 1919. This involves separating mixtures of substances into their components and transforming them into beams of particles and subsequently, bending them with the use of electricity and magnetism to come up with a spectrum that is inherently unique for every individual atoms for easy identification.
