Wind is a renewable source of energy‚ meaning turbines can harvest wind for electricity repeatedly without depleting the Earth’s natural resources. Furthermore‚ taking a bike or walking is healthier than taking a car which pollutes air to the atmosphere. Not only we can protect our planet by making sure that

Natural Selection Lab This hands-on laboratory exercise is a highly simplified model that attempts to simulate evolution by means of natural selection. Predators will act as agents of selection on their prey‚ a species whose members vary in color. We will assume that color is an inherited trait. Small squares of paper will represent the prey‚ which will be spread out of a piece of printed colored fabric that will serve as the habitat. The predators (you) will prey upon the population‚ with the surviving

Biomes and Diversity Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate? This is an interesting question. Lets consider the fact that it begins by stating extinction is a natural selection process. This seems to stifle one side of this argument.The side of the argument that rallies humans to be concerned with the extinction rate and strive to preserve a representation

Natural selection would favor groups living in areas with large amount of predators. This is because when individuals live in large groups‚ there are more eyes to watch the predators‚ and therefore‚ more time to eat. Moreover‚ it favors species that usually hunt huge animals because they can catch their prey easily. 2) Optimal flock size in birds has important benefits such as a better possibility of fending off predators. When a group of several birds are watching for predators‚ each individual

The Natural Gas Case In the Natural Gas case‚ a German company and a Dutch gas reseller (the plaintiffs) is suing an Austrian partnership company (the defendant) for a breach of contract. The plaintiffs negotiated and agreed to purchase 3000 metric tons of propane gas for $381 per metric ton from the defendant. Because of the two companies never conducting business with one another‚ the plaintiffs agreed to secure a letter of credit with its purchase. To secure the letter of credit with the purchase

January 2001 Explain the theory of Natural law (25 marks) The theory of natural law originates from Aristotle’s idea of goodness as fitness for purpose and stoic’s concept of a universal law of reason which is in agreement with nature. What we now call human nature. This point is then furthered by Aquinas who agrees with the argument but furthers it by linking it with his Christian belief by saying following this law is equivalent to following the command of God as human nature is in us inbuilt
