Summary Introduction

To explain: The sex-limited and sex-influenced traits on the basis of the fact that hormones interact with DNA to turn certain genes on and off.

Introduction: There are obvious phenotypic differences among males and females. The differences between the sexes in humans are emphasized with the help of secondary sex characteristics which include the body size, the patterns of fat distribution, muscle mass, and the development of male or female sex organs such as penis or vagina respectively.

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?
