Points and lll simple here are six living things: a person, an oak tree, a mushroom, an amoeba, seaweed, and a bacterium. what features do they all have in common? how do they differ? use the internet to aid your research.

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
