DNA- is the material found in the nucleus that contains the genetic info. 4 billion codes in length Gene- a segment of DNA that controls a certain protein production. A gene is made up of hundreds to thousands of codes. Chromosomes- genetic material that is coiled up into structures during cell division. Importance of DNA- genes control the production of proteins..(look like‚ body function‚ body communications‚ and enzyme control) DNA screening- the process of testing individuals to determine

TASK 3 COMPONENTS OF BLOOD AND TRANSPORT OF OXYGEN Blood components are red cells‚ white cells‚ platelets and plasma. These can be put to different uses. RED BLOOD CELLS Red blood cell also known as erythrocytes make up 45% of blood volume lacks nucleus and contains the oxygen-carrying protein haemoglobin‚ which is a pigment that gives whole blood its red colour. Erythrocytes are produced inside of red bone marrow. Its main function is to distribute oxygen to body tissue‚ and carry waste

Energy Metabolism Respiration and the Respiratory System- The respiratory system is in charge of getting the oxygen needed for respiration to the blood flow where it is passed by the blood cells around the body to reach each living cell. The lungs have a huge blood supply and a huge surface area so they are very effective at getting oxygen out of the air. They are also in charge of getting rid of the carbon dioxide excess and some of the excess water as water vapour. It is the lungs job to
