Alecia Rae Atiyeh Winter 2011 Nuclear Fusion Vs Fission At the speed we are using up fossil fuels, nuclear energy is looking more and more like a possible replacement. Nuclear energy is created in two ways, through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together

Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential

BIOL/ BMSC 114: Asexual vs. sexual reproduction Asexual and sexual reproduction • Two modes of animal reproduction: asexual and sexual reproduction. – In most cases asexual reproduction relies on mitotic cell division. – Sexual reproduction is the creation of offspring by fusion of haploid gametes to form a zygote. • Gametes are formed by meiosis. • Sexual reproduction directly reduces your contribution to the next generation!

water waves, swaves (earthquakes). The major difference between longitudinal and transverse waves is their direction. Longitudinal waves move left to right while transverse waves move up and down. 5. Compare and contrast: light waves vs. sound waves Light waves are transverse and sound waves are longitudinal. Light waves can travel through a vacuum but sound waves cannot. Speed of light is nearly 300 million m/s while sound has a speed of about 340 m/s. 6. What changes the pitch of sound

Answers to Conceptual Integrated Science End-of-Chapter Questions Chapter 1: About Science Answers to Chapter 1 Review Questions 1 The era of modern science in the 16th century was launched when Galileo Galilei revived the Copernican view of the heliocentric universe, using experiments to study nature’s behavior. 2 In Conceptual Integrated Science, we believe that focusing on math too early is a poor substitute forconcepts. 3 We mean that it must be capable of being proved wrong. 4 Nonscientific
