Demonstrate how to set up a microscope and skilfully prepare microscopic slides in order to observe and draw stages in mitosis and meiosis. Explain the structure and function of chromosomes and discuss and evaluate how their behaviour during mitosis and meiosis leads to variation. Skilfully and independently prepare: Three microscope slides to observe a minimum of four stages of mitosis, for example- root tip squash. Three microscope slides to observe a minimum of four stages of meiosis...

Provide an illustrated report that assesses the impact of error in the stages of protein synthesis, discusses the functional role of nucleic acids in the stages of protein synthesis and explains the structure and function of nucleic acids. Explain the nucleotide structure and main features of the following nucleic acids: DNA- stages and enzymes involved in DNA replication. RNA- mRNA, tRNA, rRNA, and siRNA. Discuss the functional role of these nucleic acids in protein synthesis and the...

This is a distinction awarded assignment about Nutrition and health Before food can be digested, it must first be ingested, which is the process of taken food into the body (eating). Food is first mechanically digested by the teeth (chewing) then chemically digested by enzymes; amylase in the saliva, proteases and carbohydrases in the stomach and small intestines. As the food travels through the digestive tract by peristalsis, it is assimilated and nutrients absorbed. Waste is then egeste...

This is a distinction awarded assignment about The Lymphatic system The lymphatic system is made up of a network of tissues, organs and vessels that all work together to move lymph, which is a colourless fluid, back into your circulatory system. The main function of the lymphatic system is to work as our immune system, to filter out harmful pathogens in the blood, to discard waste material from cells and transport beneficial nutrients.

This is a distinction awarded assignment about The Musculoskeletal System and Disorders Related (Unit 8 Aim A) The musculoskeletal system involves the skeleton and muscles working together with various types of tissue to allow our body to perform various functions. When there is a disruption to any aspect of this delicate system, basic functions such as movement or protection are compromised. These conditions can be acquired or genetic and often cause a domino effect; this can lead to a co...

Provides an in depth description of the lymphatic system and explanation of its functions. Uses labelled diagrams to aid description showing lymph nodes and lymph vessels. Explains T and B lymphocytes and an in depth explanation of how the lymphatic system works. Also shows diagrams of different lymphatic organs and an explanation of how these come into play.

This assignment looked at the first human body system, the muscoskeletal system where first I showed a diagram of the human skeleton where I labelled every bone. After this, I described the structure and function of some bones in the body. I then went on to explain the different types of joints that are present in the body, what type of movements these joints carry out and where these can be found (as well as using diagrams). Then, I explained the different types of muscles including the locatio...
