Reproductive Biology in Humans

Can you please help me understand the answers to the attached multiple choice questions on human reproduction?

Living species around you

Start by observing the living species around you. Ever wonder why a pollinator is attracted to a particular flower, or what would happen to predator species if a particular prey species is eliminated? If you were a scientist you could do an experiment to answer your question. For this assignment, choose two non-human species that interact with each other, such as bees and flowers, or predator and prey species, or two species that compete. Or, you can consider the effect of an environmental factor on living non- human organisms, such as the effects of light or sound on plants or animals, or how food preference, or nutrient quantity / quality affect plants or animals. These are just a few... click for more

Food: How does it break down?

Can you help me find the nutritional values/info in food from USDA Nutrient Data Laboratory? Select a food. Use the USDA website to analyze the nutritional components and composition in terms of carbohydrates, lipids, and proteins (including molecular structure). Assess calories, vitamins and minerals. Is this food recomended?

Biotechnology and reproductive cloning.

Biotechnology allows us to use living organisms or their processes for human needs or purposes. This current topic includes such examples as cloning, stem cells (adult, umbilical cord, and embryonic), DNA fingerprinting, biological warfare, bioremediation, genetically modified organisms, vaccines, and transgenic plants and animals to name a few. Research how biotechnology is used today and answer the following questions: 1. What biotechnology application did you choose? 2. Briefly describe this process or application. 3. What benefits are derived from this? 4. Are there any concerns or negative impacts associated with this use of biotechnology? Why or why... click for more
