Internal Assessment 3.2 Biology Research a contemporary biological issue Introduction Stem cells are undifferentiated cells able to differentiate into specialized cell types. These are used for stem cell treatment‚ which is an intervention strategy that introduces new adult stem cells into damaged tissue in order to treat disease or injury. For over 30 years‚ bone marrow and‚ more recently‚ umbilical cord blood stem cells have been used to treat cancer patients with leukaemia and lymphoma because during

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

Dissect a Plasma Membrane Objective: to understand the structure of a membrane 1. Why is the membrane described as a phospholipid bilayer? It is described as a phospholipid bilayer because there are two layers of phospholipid molecules. 2. How does the arrangement of the phospholipids form a bilayer? The phospholipids arranged in two layers so that the charged phosphate heads interact with the water on either side of the membrane‚ and the lipid-like (hydrophobic) tails point away from the

individual different. DNA is the molecule that makes up chromosomes each pair of chromosomes contains DNA from one parent. DNA is found in the nuclei of eukaryotic cells and prokaryotic cells in living organisms. DNA is so important it is unable to leave the nucleus therefore the body makes RNA to carry information out into the cytoplasm. The three major components of DNA nucleotide monomers are phosphate‚ 5 carbon ring sugar (de-oxyribose) and a nitrogenous base. The orientation of the sugar determines
