Summary Introduction

To contrast: The nutritional mode of fungus and humans.

Concept introduction: Nutrients are the substances in food that maintain the body and make it work. Fungi are multicellular eukaryotes (except yeast) and are classified according to their structure and mode of reproduction. Fungi are achlorophylous (do not contain chlorophyll and not able to make food). They are heterotrophic feeders as they depend on other organisms for the carbon source. Unlike humans, they do not ingest their food but instead absorb nutrients from the surrounding environment by secreting various hydrolytic enzymes or act in the form of saprobes, symbionts, or parasites. By contrast, humans have the holozoic mode of nutrition; they relatively ingest large pieces of food and thus, digest the food in their bodies.

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?
