Bustamante Roscoe’s Journey through the Respiratory System Hi my name is Roscoe and I am an oxygen cell. I was told by my grandfather Gene that I was a very important cell. He told me that when someone takes a breath they take in all types of molecules in the air including myself. My grandfather was a very wise man and whenever he talked I listened. “You will take a very important path around the body one day Roscoe‚” my grandfather said to me. “Really grandpa‚” I asked. “Yes‚ through the

Properties of life‚ Basic Chemical Terminology‚ Molecules and Compound of a cell Properties of life: All living things are made of cells and keep certain characteristics in common. All living things are divided into several characteristics: order‚ reproduction‚ growth and development‚ energy processing‚ respond to the environment‚ regulation and evolution. Cells are either made of prokaryotic or eukaryotic. Prokaryotic is simple‚ small and lacking membrane-enclosed membrane. Eukaryotic

Origin of Eukaryotes * The origin of eukaryotes is important to understand the origin of modern complex cells. There are three main separate theories that hypothesize the origins: the three-domain system‚ eocyte theory‚ and endosymbiosis. Each one have there own merits and evidence supporting. These theories suggest the evolution of cells from the most primitive prokaryotes‚ unicellular organism having cells lacking membrane-bound nuclei‚ to the most complex eukaryotes‚ single or multicellular

The way that the molecules move across the cell membrane is that the carbon dioxide molecules spread out rapidly out your red blood cells down their concentration gradient to your lungs. When water molecules move freely through your cell membrane is called osmosis as we learned last unit. The reason why molecules move across the cell membrane is because they are small molecules that have no charge like oxygen which the cell membrane need to survive. So basically the molecules that move across the

Strengths and weaknesses of the service industry in the UAE Student name: Rashed Salem Al Mansoori ID: 111 210 153 Economy of countries is composed of different sectors that work together in an integrated way so as to form the entire economy of the country . The importance of the role that each sector plays in the economies of countries differs from one country to another as a result of the strength or weakness of that sector. Regarding the UAE ‚ it is a country of a strong economy especially

Yafaa Chaudhary PHYSICS 5 NOTES Physics 5 3.5.1 Radioactivity Evidence for the nucleus Qualitative study for the Rutherford scattering. Rutherford directed a narrow beam of α-particles‚ all of the same kinetic energy‚ in an evacuated container at a thin gold film‚ in order to identify the structure of an atom: The α-particles need to be of the same kinetic energy otherwise slow α-particles would be deflected more than faster α-particles on the same initial path. The container needs to be evacuated

Extraction of DNA from Calf or Hog Thymus/Isolation of Yeast RNA I. Abstract Nucleic acids may be divided into two groups RNA and DNA. DNA contains almost all the genetic information while RNA serves as the bridge between the DNA and proteins. Study of both DNA and RNA initially involves proper extraction/isolation. The storehouse of eukaryotic DNA is the nucleus (and in the mitochondria)‚ so experimentally‚ DNA is extracted from tissues that have a high nuclear to cytoplasmic mass ratio‚ such

DNA Transcription The process of transcription is where a copy of a gene is made within DNA to use as RNA. It is located in the nucleus of eukaryotes and in the nucleoid of prokaryotes. DNA stores information encoded in a genetic code. The code consists of four letters and they are T (thymine)‚ G (guanine)‚ A (Adenine)‚ and C (cytosine). One gene codes for on protein. RNA is a molecule that copies information that is coded in another genetic code. This code also consists of the same four
