Why are some fruits sweet and some sour, whereas others have no specific taste? How does the ripening of fruit affect the process of seed dispersal? How do humans interfere in this process by consuming grains and fruits? Does the seed use the fructose or starch in fruits for its metabolism?

Charts and tables are tools we use in science to break down information analytically and present data in an organized manner. It is a beneficial strategy for learning about and organizing scientific material, which we will be using often in this class. Make sure that you are detailed, thorough, and specific in your responses. Explain yourself clearly. Do not list a word or brief phrase without explaining what it means. For example, if you list diabetes for carbohydrates, make sure you explain how carbs are associated with diabetes. Don't leave the reader to make that connection for you. Also, make sure you provide APA-style references for each of your so

1. The Brazil nut tree, Bertholletia excels (n = 17), is native to tropical rain forests of South America. It is a hardwood tree that can grow to over 50 meters tall, a source of high-quality lumber, and a favorite nesting site for harpy eagles. As the rainy season ends, tough-walled fruits, each containing 8-25 seeds (Brazil nuts), fall to the forest floor. Brazil nuts are composed primarily of endosperm. About $50 million worth of nuts are harvested each year. Scientists have discovered that the pale yellow flowers of Brazil nut trees cannot fertilize themselves and admit only female orchid bees as pollinators. The agouti (Dasyprocta spp.), a cat-sized rodent, is the only animal with teeth strong enough to crack the hard wall of Brazil nut fruits. It typically eats some of the seeds, buries others, and leaves still others inside the fruit, which moisture can then enter and allow the remaining seeds to germinate.
The large white part of a Brazil nut that people eat serves which of the following functions in nature?
A. It serves as protection for the embryo from agoutis looking for food. | ||||||||||||||||
B. It attracts harpy eagles and encourages them to nest in the tree. | ||||||||||||||||
C. It provides energy and nutrition to a germinating seedling. | ||||||||||||||||
D. It provides a water source for the developing embryo. 2. Scarlet gilia (Ipomopsis aggregata) usually has red flowers in an inflorescence of up to 250 flowers. In certain populations in the Arizona mountains, however, the flowers range from red to pink to white. In early summer, most (but not all) of the flowers were red. Six to eight weeks later, the same individual plants were still present; the flowers ranged from pink to white, and few red flowers were present. The major pollinators early in the season were two species of hummingbirds active during the day; they emigrated to lower elevations, and the major pollinator later in the season was a hawk moth (a type of moth). The hawk moth was most active at sunset and later, and it preferred light pink to white flowers after dark. When hummingbirds were present, more red flowers than white flowers produced fruit. When only hawk moths were present, more white flowers produced fruit (K. N. Paige and T. G. Whitham. 1985. Individual and population shifts in flower color by scarlet gilia: A mechanism for pollinator tracking. Science 227:315-17).
3. Mistletoe is a plant that lives on trees and gains nutrition from them (that is, it is a parasite). The fruit of the mistletoe is a one-seeded berry and is consumed by birds. In members of the genus Viscum, the outside of the seed is viscous (sticky), which permits the seed to adhere to surfaces such as the branches of host plants or the beaks of birds. What should be expected of the fruit if the viscosity of Viscum seeds is primarily an adaptation for dispersal rather than an adaptation for infecting host plant tissues? The fruit ________.
