Answer:
A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below). The Bohr model shows the three basic subatomic particles in a simple manner. Most of an atom's mass is in the nucleus—a small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged. Electrons, which are negatively-charged, are located outside of the nucleus.
Bones contain bone cells in lacunae, which are tiny chambers arranged in circles and canals. The canals contain blood and nerves.
Answer:
The answer is A, to serve as an outgroup.
Explanation:
The study of any phylogenetic group requires that there must be an outgroup that can serve to understand which characters are plesiomorphic (or ancestral) and how they changed over the years to a new evolved character. In this case, Lily, since it is not a member of the group which is under study (orchid), serves as an outgroup.
