Compare the plant embryo to the animal embryo. Can you make inferences about the evolutionary relationship between animals and plants based on what the embryos look like?

Plants show immediate growth, animals do not at first. The cells of plants differ immediately, whereas this is not the case with animals. Animals bend inwards and make a body cavity and plants do not form an inner space.

In Bohr's model, electrons traveled in fixed orbits around the nucleus of the atom, much like planets around the sun. However, resent discoveries have led to the new atomic theory, in which electrons are randomly in an electron cloud around the nucleus: more dense in some places than others.
