A. Prokaryotes are separated into two of the three domains of life: the Archaea and Bacteria.
1. Archaea often live under extreme conditions of salinity (high salt), acidity, temperature, and other
environments not tolerated by other organ
INFORMATION FLOW AND THE NEURON
A. Our activities (such as movement involved in playing Frisbee) depend on the functions of only two major
cell types: neurons and glial cells. (The neurons are the nerve cells; the glial cells play a supporting role)
A. Kingdom Plantae covers more than at least 260,000 living species separated into 10 phyla.
B. The first plants are hypothesized to have lacked seeds, and include the mosses, horsetails, and ferns.
