2. Lead is toxic, but do you know why? Lead is toxic mainly because it preferentially replaces other
B B B B B B B B B B B B B B B B
B metals in biochemical reactions. In so doing it interferes with the proteins that regulate blood pressure
B B B B B B B B B B B B B B B
B(which can cause development delays in children and high blood pressure in adults), heme
B B B B B B B B B B B B B
production (which can lead to anemia), and sperm production. Lead also displaces calcium in
B B B B B B B B B B B B B B
the reactions that transmit electrical impulses in the brain, which diminishes the ability to think and

3. Aristotle focused on clarifying the concept of virtue itself. He argued that it was virtuous to choose the
B B B B B B B B B B B B B B B B B
proper amount of emotion and/or action called for in a particular situation and that extremes of
B B B B B B B B B B B B B B B B

4. Illegal immigrants pay local sales taxes, and many of them also pay state, local, and federal income tax
B B B B B B B B B B B B B B B B B
and Social Security tax. They also purchase items from local merchants, increasing the amount these
B B B B B B B B B B B B B B B
Bmerchants pay in taxes. In addition, they work for low salaries, which increases the earnings
B B B B B B B B B B B B B B

6. It's even more important these days that your computer be protected by a firewall. There are criminal
B B B B B B B B B B B B B B B B

planetologists.

9. Humans are biological organisms. To understand our behavior and mental processes, we need to
B B B B B B B B B B B B B
understand their biological underpinnings, starting with the cellular level, the neuron. How

we feel, learn, remember, and think all stem from neuronal activity. So, how a neuron works and how
B B B B B B B B B B B B B B B B B B
neurons communicate are crucial pieces of information in solving the puzzle of human behavior
B B B B B B B B B B B B B B
and mental processing.

10. Viruses are acellular entities too small to be seen with a light microscope. They are composed of a
B B B B B B B B B B B B B B B B B
nucleic acid and a few proteins. Viruses replicate themselves and display other properties of living
B B B B B B B B B B B B B B B
organisms only when they have invaded living cells. Indeed, some viruses can be crystallized and
B B B B B B B B B B B B B B B
stored in a container on a shelf for years, but they retain the capacity to invade cells and cause disease.

82 percent since 1981. Solar energy technology has made remarkable progress as new photovoltaic
B B B B B B B B B B B B B B
