Nervous tissue is made up of neurons and supportive cells. Throughout the human body the neurons carry electrical and chemical signals, while nutrition is provided by the supportive cells.
Seed plants have an evolutionary advantage for several reasons. For one, the seeds can disperse easily. Furthermore, seeds can time their germination. For example, some seeds only germinate when they experience a period of being frozen.
The reaction that links monomers to make polymers is polymerization. This process is also referred to as dehydration synthesis. Two monomers are binding to each other and form one polymer. Example: hydrogen (H) from one monomer binds with a hydroxyl group (OH) from the other monomer and forms the polymer : H+<span> + OH</span>-<span> = H</span>2O - the <span>water molecule. </span>
