How does the law of polystyrene affect consumers?
The law of polystyrene affects consumers because of the chemmicals inside the material and the polystyrene is burned underground and the chmicals gets into the environment which can make consumers sick
What cell transmits and receive nervous-system signals?
The dendrites collect information from other cells (afferent) or send information to other cells (efferent). The afferent dentrites are stimulated by chmicals from sensory cells. The efferent dentrites send chemical signals to other cells.
How did life begin according to the evolutionary theory?
The Theory of Evolution does not seek to how life began, although there are several very credible hypotheses for the beginning of life on Earth. The traditional view is that, billions of years ago while the Earth was still hot and there was extreme volcanic and lightning activity, organic chemicals began to form out of the simpler inorganic chmicals that abounded. These organic chemicals became more and more complex, until RNA molecules (the precursors to DNA) formed. Once RNA, and then DNA molecules existed, life was ready to begin. Another hypothesis is based on the ability of some crystals to replicate themselves, even replicating the defects that occasionally formed. In a 'dirty' environment, carbon atoms could attach themselves to those crystals and become replicated along with the crystal itself. This self-replication is not yet life, but could conceivably lead to the development of life.
