Examine their efforts to protect a few specific ecoregions.  What if the government of one of these ecoregions determined it was necessary to develop parts of the region to free up land for agriculture and housing, as well as harvest valuable resources essential to the economic growth and prosperity of the country? Furthermore, this project would provide homes to the homeless and help alleviate poverty in the region.

• Is protecting the biodiversity of the environment and salvaging ecoregions from development more important than human progress and prosperity? Is it more important than alleviating poverty, hunger, and other social issues? Why or why not?

• Is sustainability more important than economic growth? Why or why not?

• How would you respond to this situation?

Two gene loci, A and B, assort independently, and alleles A and B are dominant over alleles a and b. Indicate the probablilities of producing .... an AB phenotype from a cross AaBb x AaBb. Not sure if I did this correctly but my answer came out to :1/4 x 1/4 = 1/16

I have no idea how to do this: two gene loci, A and B, assort independently, and alleles A and B are dominant over alleles a and b. Indicate the probability of producing:an AB phenotype froma cross aabb x AABB

Two gene loci, A and B, are ulinked (and thus assortindependently), and alleles A and B are dominant over alleles a andb. What is the probability producing an AB gamete from an AaBbindividual?

Drug X has been tested in clinical trials to treat mitochondrial function diseases. It has some efficacy, but too many side effects. You are working on a project to develop a drug that would be as effective as X, but without side effects. However, you don’t know what cellular function or pathway is affected by the drug. What experiment can you do to gain insight into this problem?
