GCSE Biology for teaching from September 2011 onwards (version 1.1) 3.3 Unit 1: Biology 1 B1.1 Keeping healthy Subject Content A combination of a balanced diet and regular exercise is needed to help keep the body healthy. Our bodies provide an excellent environment for many microbes which can make us ill once they are inside us. Our bodies need to stop most microbes getting in and deal with any microbes which do get in. Vaccination can be used to prevent infection. Candidates should use

and Nagasaki. I only support this devastating attack because of what Japan did to the U.S and the bombing of Pearl Harbor. I do not support it when we do it just to kill thousands of people without a reason. It’s a lot cheaper and easier to create pathogens then to invent new form of weaponry in the gun or tank department. The U.S is a very powerful county with a big target on it for terrorist attacks. I like the thought of Biological engineered viruses because they can be used to create a sense of

Genetics: the science of heredity that includes the study of what genes are‚ how they carry info‚ how they are replicated and passed to subsequent generations of cells or passed between organisms‚ and how the expression of their info within an organism determines the particular characteristics of that organism. Genome: the cell’s genetic information that includes it’s plasmids and chromosome. Chromosomes: structures containing DNA that physically carry hereditary info‚ contain the genes Genes:

They function to guard against inhaled and ingested pathogens. They have deep pits that catch bacteria and food debris. E. What are the structural similarities found in lymph nodes‚ spleen and tonsils? a. They all have a capsule‚ they are rounded organs with an internal parenchyma of lymphoid cells

CHAPTER 3 The Legal Environment: Equal Employment Opportunity and Safety Chapter Summary The legal environment is one of the critical environmental factors that affects the management of people. This chapter first describes the U.S. legal system‚ including the legislative bodies‚ regulatory agencies‚ and judicial bodies whose decisions affect the legality of HRM practices.

placement. What is a hazard? A hazard is anything that has the potential to cause harm. Risk is the likelihood of that harm. For example hazards in terms of infection control are pathogens. Some pathogens are considered a greater risk to others‚ for example MRSA (super bug) or Clostridium difficile. What casues pathogens to grow? Baceteria grow by splitting in two. In ideal conditions bacteria can divide every 20 minutes‚ so the size of the colony doubles every 20 minutes. In theory a colony of

Management of soil borne diseases mainly involves use of preventive measures because it is harder to control the disease once established. Thiram and carbendazim are used in majority of the crops as seed dress fungicides against a wide variety of pathogens. The efficacy of the rates of these two fungicides against Fusarium wilt of chickpea was evaluated at four levels (0%‚ 50%‚ 100% and 150%) of the recommended rate
