Killing animals for food: for & against The question of killing animals for food is very difficult because there are a lot of different reasons for people to kill animals and a great number of reasons why we mustn’t do it. Of course we can’t imagine our life without meat‚ sausages and other tasteful meals made of meat. But I think it’s really cruel and inhuman to kill animals. We are not gods and it’s not up to us to decide if they must live or should be killed. Who gave us the right to

Investigating the Water Potential of a Potato. I have been asked to investigate the water potential of a potato. During my investigation I will not actually be able to measure a value for‚ as it is a pressure value (kPa). Osmosis is a special form of diffusion involving only water molecules. It is defined as "The passage of water from a region of high water potential to a region of low water potential through a partially permeable membrane" Definition of Water Potential. The potential for water to move

an electric light and a dark room becomes bright. Turn on a music player and sound comes through your headphones. In both situations‚ energy moves from one place to another; effect and reaction. The two different types of energy are kinetic and potential energy. Kinetic energy is the energy a moving object has because of its motion. The kinetic energy of a moving object depends on the object’s mass and its speed. The kinetic energy of a moving object can be calculated from this equation: Kinetic

a man lying on the floor‚ then looked up into the barrel of a semi-automatic rifle. He dived back out the door as Martin Bryant pulled the trigger. Bryant killed 12 people in 15 seconds. Bryant moved towards the gift shop in the next 75 seconds‚ killing another eight people. In little over half an hour the 35 were killed and‚ 23 wounded. This became the worst single-person mass shooting in Australia’s history; and is still the third worst recorded worldwide. Bryant’s gun was an AR-15 rifle with a

The theme of The Killing Sea by Richard Lewis is family. In The Killing Sea Sarahs family gets split apart when the tsunami hits. Sarah’s first thought when she wakes up after the tsunami is that her family is most likely dead‚ when she finds Peter she almost never lets him out of her sight again. When the 2004 indonesian tsunami hits many people were separated from their family. An example is that according to bbc news 228‚000 people were killed in this tsunami. These people probably had family

Star Trek the Space Seed In the episode of Star Trek‚ titled Space Seed by Gene Roddenberry‚ there are plenty of examples of science fiction. At the very start of this episode and almost every Star Trek episode you see the crew in a spaceship flying in space‚ called the starship enterprise. This is one example of science fiction because even though we have spaceships now‚ in Star trek they can somehow cancel out gravity so they don’t need to wear space suits like we do today. Also the starship

Introduction Molecules are constantly in motion due to thermal energy. Therefore‚ the molecules will move around and bump into each other. Because of this‚ molecules tend to spread out evenly into available space in a process called diffusion. Diffusion is the random process of molecules moving from areas of high concentration to low concentration‚ thus requiring no energy. Many of the substances that enter or leave the cell do so through diffusion. Osmosis‚ a type of diffusion‚ is the movement

The Scam in Mercy Killing Imagine one of your family members is terminally ill and presumed she will die very shortly. This is a controversial topic where some people want to die with dignity. So many people can choose Euthanasia to assist them in dying peacefully. So many of these people approximately 3‚147 cases are put under this pressure to end their lives and say god-bye. Euthanasia is the putting to death by painless means or in Greek language it means a good death. Either you can do this
