2. Lead is toxic, but do you know why? Lead is toxic mainly because it preferentially replaces other
t t t t t t t t t t t t t t t t


metals in biochemical reactions. In so doing it interferes with the proteins that regulate blood
t t t t t t t t t t t t t t t


tpressure(which can cause development delays in children and high blood pressure in adults), t t t t t t t t t t t t


heme production (which can lead to anemia), and sperm production. Lead also displaces
t t nn t t t t t t t t t t


calcium in the reactions that transmit electrical impulses in the brain, which diminishes the ability to
t t t t t t t t t t t t t t t t


think and recall information.

3. Aristotle focused on clarifying the concept of virtue itself. He argued that it was virtuous to choose
t t t t t t t t t t t t t t t t


ttheproper amount of emotion and/or action called for in a particular situation and that extremes of
t t t t t t t t t t t t t t t


temotion and action were vices. In all communities there are some men of practical wisdom who
t t t t t t t t t t t t t t t


have the capacity to judge wisely. Aristotle argued that they have the capacity to follow the "right
t t t t t t t t t t t t t t t t t


rule" whatever the situation.

4. Illegal immigrants pay local sales taxes, and many of them also pay state, local, and federal income
t t t t t t t t t t t t t t t t


taxand Social Security tax. They also purchase items from local merchants, increasing the amount
t t t t t t t t t t t t t t


tthese merchants pay in taxes. In addition, they work for low salaries, which increases the
t t t t t t t t t t t t t t


tearnings of their employers and the amount of taxes these employers pay. Thus, it is not correct
t t t t t t t t t t t t t t t t


tto say that illegal immigrants contribute nothing to the communities in which they live.

5. Numerous studies have indicated that women of color, black women in particular, are over- arrested,
t t t t t t t t t t t t t t


over-indicted, and over-sentenced. African-American women are seven times more likely to be
t t t t t t t t t t t t


arrested for prostitution than women of other ethnic groups. Black women have received
t t t t t t t t t t t t t


tsignificantlylonger sentences for crimes against property and served longer periods in prison. For t t t t t t t t t t t t


both murder and drug offenses, Euroamerican women ended up serving one-third less time for the

6. It's even more important these days that your computer be protected by a firewall. There are
t t t t t t t t t t t t t t t


criminal elements lurking in the shadows of cyberspace who send out probes to detect unprotected
t t t t t t t t t t t t t t t


PCs. Once a vulnerable computer is found, these criminals install software that assists them in
t t t nn t t t t t t t t t t t


committing identity theft and fencing stolen IDs. They also defraud online advertisers by
t t t t t t t t t t t t t


using these zombie computers tovisit pay-per-click ads.

7. The earth is of interest to astronomy for many reasons. Nearly all observations must be made
t t t t t t t t t t t t t t t


through the atmosphere, and the phenomena of the upper atmosphere and the magnetosphere
t t t t t t t t t t t t t


reflect the state ofinterplanetary space. The earth is also the most important object of comparison for
t t t t t t t t t t t t t t t t


planetologists.

8. If the trade in tiger products is banned, tiger reserves are guarded by well equipped staff,
t t t t t t t t t t t t t t t


communities abutting tiger habitat are given a stake in protecting tigers, and the makers of

traditional medicines canbe persuaded that tiger parts are not needed, then tiger poaching will be
t t t t t t t t t t t t t t t


halted, habitat and life sustaining prey will be restored, and the immanent extinction of tigers in

the wild will be averted.

9. Humans are biological organisms. To understand our behavior and mental processes, we need to
t t t t t t t t t t t t t


understand their biological underpinnings, starting with the cellular level, the neuron. How we feel,
t t t t t t t t t t t t t t


learn, remember, and think all stem from neuronal activity. So, how a neuron works and how
t t t t t t t t t t t t t t t t


neuronscommunicate are crucial pieces of information in solving the puzzle of human behavior
t t t t t t t t t t t t t


and mental processing.

10. Viruses are acellular entities too small to be seen with a light microscope. They are composed of a
t t t t t t t t t t t t t t t t t


nucleic acid and a few proteins. Viruses replicate themselves and display other properties of living
t t t t t t t t t t t t t t t


organisms only when they have invaded living cells. Indeed, some viruses can be crystallized and
t t t t t t t t t t t t t t t


tstored in a container on a shelf for years, but they retain the capacity to invade cells and cause
t t t t t t t t t t t t t t t t t t


disease.

11. Harnessing the clean, abundant energy of the sun and wind is critical to solving the global
t t t t t t t t t t t t t t t


warming problem. Technological advances have brought the cost of electricity generated by the
t t t t t t t t t t t t t


wind down by82 percent since 1981. Solar energy technology has made remarkable progress as
t t t t t t t t t t t t t t


new photovoltaic cells have been developed to convert even greater amounts of sunlight directly
t t t t t t t t t t t t t t


into electricity. Todaythe costs of wind and solar power are becoming competitive with dirty

coal-fired plants.

12. It is likely that innocent prisoners in this country have been executed for crimes they did not
t t t t t t t t t t t t t t t t


commit. From 1973 until 2007, 124 death row inmates have been exonerated. In many of
t t t t t t t t t t t t t t t


tthese cases DNA evidence played a crucial role. Yet, in that same time frame, more than 1000
t t t t t t t t t t t t t t t t


prisoners were executed. For many of these prisoners no DNA evidence was available. If such
t t t t t t t t t t t t t t t


evidence had been available, howmay more would have been exonerated?
