Sep. 21‚ 2014 Stem Cells Stem cells are the beginning of organism creation and have the potential to separate‚ becoming any kind of organism‚ endlessly. These cells have not gone through the process known as differentiation‚ which gives the cell a specific function. Technically‚ due to research over the recent years‚ scientists could grow certain organs with through stem cells because of the fact that these cells can be manipulated early on. There are multiple stem cells that have been determined

Social scientists have noticed that the concept of the family has changed in the past 40 years‚ and this has led some to comment on the ’disintegration of the nuclear family’. Do you agree with the claim that the nuclear family unit is breaking down? The conventional nuclear family model‚ Murdock first spoke of‚ which entails the father as the employed bread winner and the wife as the stay at home housewife and mother looking after their children. This early idealistic model of the stable family

constantly changing. The “normal” American family is known as the nuclear family‚ with a mother‚ father‚ son‚ daughter‚ and occasionally‚ a pet. But as time has progressed‚ the nuclear family has had to make room for larger families‚ single parent families‚ biracial families‚ and families with step and half relatives in them. After WWII‚ the American family’s structure changed drastically‚ with many types of families appearing‚ aside from the nuclear family structure. The baby boom led to larger families

P6- Describe different types of energy transfer For us to do work‚ we need energy. Energy is measured in joules‚ (J) or kilojoules (kJ) Energy exists in many different forums such as Kinetic and potential energy – Kinetic energy is the movement of energy and potential is stored energy‚ energy ready to go. A lawn mower filled with gasoline‚ a car on top of a hill‚ and students waiting to go home from school are all examples of potential energy. Gravitational potential energy is the energy crazed

The Nuclear Weapon Controversy The question of whether countries should have nuclear weapons or be able to test them is a very controversial topic among the public. "A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions‚ either fission or a combination of fission and fusion." (Vicky: "Nuclear Weapon"). The destructive atomic bomb is an example of a nuclear weapon. The United States used the atomic bomb to destroy the cities of Hiroshima and Nagasaki‚

The fluid mosaic model of the cell membrane. What is the fluid mosaic model? The fluid mosaic model is a model conceived by S.J. Singer and Garth Nicolson in 1972 to describe the structural features of biological membranes. The membrane is described to be fluid because of its hydrophobic integral components such as lipids and membrane proteins that move laterally or sideways throughout the membrane. That means the membrane is not solid‚ but more like a ’fluid’. The membrane is depicted as mosaic

The prokaryotic cell precedes any forms of Bacteria‚ Archaea‚ and eventually Eukaryotes by approximately two billion years. This cell was the original life form on the planet and represents the smallest and least complex of all organisms. Through the process of mutation and adaptation they were able to survive to evolve into our modern day Bacteria‚ Archaea‚ Fungi and Protists. These post organisms have benefited from their early ancestor‚ by way of Endosymbiosis. Intricate protest and fungi are

consist of protons and neutrons‚ which have a positive or negative charge. Electric forces are repulsive between similar charges‚ so there must be a force much stronger than electromagnetism keeping them together. This force is called the Strong Nuclear Force‚ and it is about a hundred times stronger than the electromagnetic force. Its strength allows it to hold a nucleus together‚ despite the desire of the electromagnetic force to thrust it apart. Despite its relative strength‚ the strong force
