Summary Introduction

Introduction: Hybrid offspring is produced when organisms of two species are mated. However, there are certain barriers that obstruct the mating of two species known as reproductive isolation. Allopatric speciation occurs when geographic isolation restricts the gene flow, whereas sympatric speciation does not occur due to geographic isolation and may be caused by certain mutation, natural or sexual selection. There will be three possible outcomes if closely-related species mate over time- reinforcement of barriers, fusion of species, and stability.

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?
