FOCUS ON INFORMATION

A typical prokaryotic cell has about 3,000 genes in its DNA while a human cell has almost 21,000 genes About 1000 of these genes are present in both types of cells. (a) Based on your understanding of evolution explain how such different organisms could have this same subset of 1,000 genes. (b) What sorts of functions might these shared genes have? Justify your choices

What are biofertilizers and mention the significance

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans? Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.

Other than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)? How is water unique compared to these other liquids? What follow-up experiment would you like to do, and how would you relate it to your life?
