Based on what you have learned about emotion and motivation, learning theories, as well as biological (nature) and environmental/social (nurture) factors, explore the debate on what is known about the causes of aggressive behavior. Include the following sections in your essay.

Introduction Paragraph

Body Paragraphs:

Nature: Biological Basis of Behavior

Is one gender naturally (genetically) more or less aggressive than the other gender? Why or why not? Discuss evidence to support your position. (Refer to specific theories, models, and research of particular psychologists in this section of the paper.)

Nurture: Social and Environmental Influences on Behavior

Does exposure to aggressive behavior in the environment (i.e. home, role models, caregivers, media - TV, movies, music, and video games), encourage or discourage aggressive behavior? Discuss evidence to support your position. (Refer to specific theories, models, and research of particular psychologists in this section of the paper.)

Conclusion Paragraph

Based on what you have learned about biological and environmental influences on behavior, which plays a more influential role in helping us understand aggression?

Telomeres and aging
In human blood cells, the length of telomeres steadily declines over time from 8,000 base pairs at birth to 3,000 base pairs as people age, and as low as 1,500 in the elderly (an entire chromosome has about 150 million base pairs). Each time a cell divides, an average person loses 30 to 200 base pairs from the ends of that cell's telomeres.
While telomere shortening has been linked to the aging process, it is not yet known whether shorter telomeres are just a sign of aging; like gray hair, or actually contributes to aging. After conducting some research, answer the following:

Why do cells have telomeres?
Why do telomeres get shorter every time a cell divides? What counteracts this shortening?
What role do telomeres play in aging? Conduct research about dyskeratosis congenita.
If telomerase makes cancer cells immortal, could it prevent normal cells from aging?
Do you think we could extend the average lifespan by preserving or restoring the length of telomeres with telomerase? If so, does that raise a risk the telomerase also will cause cancer?
