The difference is that photosynthesis occurs in the chloroplasts and cellular respiration occurs in the mitochondria. Another difference is the reactants for photosynthesis are different than the reactants for cellular respiration. One more difference is in photosynthesis you capture Energy from the sun and change it into food and cellular respiration is the process by which cells use oxygen to break down food and produce.

Answer:
C, a long absolute refractory period.
Explanation:
Tetanus is not possible in cardiac muscle tissue because cardiac cells have longer action potentials and a very long refractory period compared to other cells. This helps prevent the heart from cramping and seizing up.
Corpus Callosum is a band of thick fibres which connects the hemispheres of the brain.
Because the three-horned alien is heterozygous, we know that three must be dominant to four, because the gene for the three horns is "hiding" the gene for four horns. Therefore, the three-horned alien has the genotype Tt (T for three horns, and t for four horns). The four horned alien must be tt, because that is the only way that a recessive trait may be seen. If you solve the punnet square on a cross between Tt and tt, you end up with half three (heterozygous) and half four (homozygous recessive) it is a bit easier to explain with something a little "closer to home" if you want me to explain it again, just say so, I don't mind!
