Chapter 1 highlights nine properties of life. A brief description of order‚ metabolism‚ motility‚ responsiveness‚ reproduction‚ development‚ heredity‚ evolution‚ and adaptation will be provided. Also addressed‚ is how things like a virus‚ prion‚ and viroid‚ can produce‚ but are not considered to be alive. First is order. Order or structural and behavioral complexity lies in specific relationship to all other structures and activities. It is the precise arrangement of things structured together

Theme : Electrical Sector and Chemical Engineer a) “The Chemical Engineer – His Role in Electrical Manufacturing” by N.R. Maleady The article is about the role of chemical engineer in manufacturing transformers in the electrical manufacturing sector. The important components of the transformer are copper wire‚ cellulosic insulation‚ insulating varnish and dielectric liquid. Wire enamel or resin is the insulting structure for copper wire. The resin can either applied as a solution or in solventless

Material: Realms of the Earth Astro-physicists and scientists believe that there could be quite a few planets in the Universe similar to our planet Earth. There is also a probable chance that some form of life prevails and sustains in one of such planet. However‚ so far as we presently know‚ the Earth is the only planet which supports life which makes it a very unique planet. It is therefore imperative (very important and necessary) for us to understand the spheres of the Earth as the spheres play a

2013 Utopia is Not Possible If one were to ask 100 different people a subjective question‚ one is likely to elicit 100 different answers. This shows that everyone is different and has a wide range of views. Knowing this‚ one can assume that each one of their views on utopia must be equally as varied. Therefore‚ achieving a common utopia is near impossible. A utopia is a perfect place where everyone is happy both in society and in oneself. Motivation; an element of life that gives someone the

“You are not that special”‚ “Do you want to be thrown into a mental hospital?”‚ “You can’t do anything right” “retard…” Admittedly‚ this is a strange introduction when discussing about possible-selves; seeing that these quotes are highly derogatory. However‚ there is a method to my madness. That is to say‚ in view of the theory about possible selves‚ it brings up the question: if a child could overcome the trauma they endured and achieve success? Concerning my possible self‚ the years of abuse resulted

Chemical Bonding Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are: Covalent Bonds Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms‚ in contrast to the transfer of electrons in ionic bonds. Such bonds lead

I am going to talk about how gold is made. I also noticed some physical and chemical changes happening in the video. My first Physical change I saw was when they drill in a certain spot‚ on the rock then they can put the pieces back together and pretend it did not happen because the molecules have not changed in the object‚ you are just breaking them into smaller pieces. So that is why it is a physical change. A chemical change I saw is when there is gold mixed with other materials like silver and

The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth’s gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation‚ warming the surface through heat retention (greenhouse effect)‚ and reducing temperature extremes between day and night (the diurnal temperature variation).The common name given to the atmospheric gases used in breathing and photosynthesis is air. Dry air contains roughly (by volume) 78.09% nitrogen‚ 20.95% oxygen
