BIO Question, biology homework help

In October 2002, the government of Zambia announced that it was refusing to distribute 15,000 tons of corn donated by the US. The government refused the corn because it was likely to contain genetically modified kernels. The government made the decision after its scientific advisers concluded that the studies of the health risks posed by GM crops “are inconclusive”

**Do you agree with this assessment? Do you think it is a good justification for refusing the donated corn?

At the time Zambia was facing food shortages, and 35,000 Zambians were expected to die from starvation over the next six months.

**How do the relative risks posed by GM crops compare with the relative risks posed by starvation?

In this lab, you will see the time progression of impacts associated with either coal-fired or nuclear power plants for electricity generation to help you write up a scientific paper that centers on the following:

  • Given that the current 2 primary sources of electricity generation are coal and nuclear power plants, which of these sources is better for human sustainability?

Analyze Energy Sources Lab

Everything people do in their daily lives involves the consumption of resources—particularly energy. With respect to energy, electricity is one of the most important resources consumed and also one of the highest in demand. Traditionally, fossil fuels such as coal, natural gas, and oil have dominated the U.S. energy mix; however, as it is well-known, carbon-emitting energy sources are very detrimental to the environment and are contributing to global warming. Fortunately, alternative energy resources such as solar, wind, hydro, and geothermal power are becoming more efficient and prevalent in today’s energy economy.

Using the M.U.S.E. link, review the background information and gather your data.

Application: Grammatical Rules and APA Format

Credibility in the criminal justice field depends on language competence. Learning, and then internalizing, grammatical rules and the appropriate formats and styles to follow when creating a document such as a police report, is a worthwhile challenge. Recurring errors are often the result of not internalizing the rules that govern communication. Identifying grammatical errors and attempting to correct them is one of the most effective ways to eliminate those same errors in the future. With conscientious practice, you might be able to eliminate these errors from your communications.
