Answer:Tissue
Explanation:Heart muscle cells beat in unison to push blood in timing with the rhythm of the heart, at the direction of nearby nerve cells. These muscle cells could best be called. Tissue. As cell division proceeds, the cells increase in number, but also become specialized in structure and function.
Answer: C- glycolysis, krebs cycle, electron transport chain.
Explanation: Glycolysis is a catabolic reaction that comprises of series of steps that breaks down food to give off energy in a form of ATP. Pyruvate is the product of glycolysis together with two ATP molecules. Pyruvate is further broken down by joining the krebs cycle and finally the electron transport chain that transfer electrons using the redox reaction, to reduce NADH to NAD + H and FADH to FAD, creating the final product i.e ATP, Overall one glucose molecule gives 38 ATP molecules in aerobic respiration.
