QUESTION( Conservation of Energy) 1. Missy Diwater‚ the former platform diver for the Ringling Brother’s Circus had a kinetic energy of 15 000 J just prior to hitting the bucket of water. If Missy’s mass is 50 kg‚ then what is her speed? Solution: According to energy conservation‚ the kinetic energy at the bottom of the dive (15‚000J) is equal to her gravitational potential energy before the dive. We can use this fact to find her dive height: PE = mgh h = PE/mg = 15‚000J / (50kg)(9.81m/s²)

COCONUT OIL AND ITS MEDICINAL EFFECTS Edible oils are found in large amounts in our daily diets hence adding up to a great amount of fatty acids in our system. Examples are in our stews‚ some soups‚ several rice dishes‚ fried or grilled meat and fish. Many have thus perceived that oil has been the cause for several of the ailments that have plagued and still plague our race‚ especially heart disease and other related cholesterol issues (Blonz‚ 1991).Nature gives the best source of oils‚ such as

STUDY GUIDE LORENZO’S OIL Overview Lorenzo’s Oil is the story of the Odones’ race against time for the survival of their little boy. Lorenzo at age 6 develops a classic childhood case of Adrenoleukodystrophy. Augusto and Michaela Odone work tirelessly with little assistance from the medical community and the parent support group to find a therapy to stop the progression of this devastating disease. In 2001 Elizabeth Spike‚ a high school biology teacher in Rochester‚ New York‚ chose to show a film

Agricultural Land Conservation The issues of land distribution and land conservation in agriculture attract more and more attention‚ especially when the expansion of cropland is hitting a limit since much more land is conserved for environmental purposes. Soil erosion is devastating the topsoil of land as chemical fertilizers are used to increase output within a limited amount of land. At the same time‚ livestock production expands at an ever-growing speed‚ worsening the land use situation.

Conservation is the practice of protecting plants or animals‚ and their habitats. These plants and animals may be very close to extinction. North America experienced a big loss of megafauna at the end of the Pleistocene era (about 13 000 years ago). This started a program known as “Pleistocene re-wilding”. Re-wilding involves the reintroduction of extant species into areas where they became extinct in the past. This program aims to restore the evolutionary and ecological potential that North America
