Discuss the movement (of substances) inside cells Substances can travel from inside the cell out and from outside of the cell inwards across a membrane. Movement of substances also occurs inside the cell and is part of many of the processes that occur inside cells in both eukaryotic and prokaryotic cells as well as animal and plant cells. The movement of substances may occur across a semi-permeable membrane such as the phospholipid bilayer membrane on the outside of a cell in the digestive

Understand the controls required for food safety Control measures are the actions you take to minimise‚ reduce or eliminate a potential hazard from occurring. To ensure the HACCP system is effective and provides adequate control over food safety hazards‚ it is essential that the HACCP system includes: Identification of the possible food hazards at all stages Identification of all the points were hazards can be controlled Any critical control points (CCPs) The maximum or minimum limits which

hospital stays‚ and can even induce long-term disability. The transmission of pathogens occurs mainly through the hands of contaminated health care workers. Routine hand hygiene is a simple and effective practice for reducing or eliminating infections. Both Methicillin-Resistant Staphylococcus Aureus (MRSA) and Vancomycin Resistant Enterococci (VRE) are major nosocomial pathogens found in many hospitals. Each pathogen has its own regimen for appropriate hand hygiene that must be followed. There is

Homework Week 4 1. How does OSHA protect health care employees? OSHA is in place to help with strong reminders of the potential dangers existing in a health care facility. These reminders help health care facilities to function safely‚ efficiently and for safety and security incidents that seem to create a serious threat to the financial well-being of any health care organization. 2. What should be included in a waste management plan? • Define and designate those wastes to be considered and

more significant impact in terms of lives saved” said Dr. Baker the director of the medicine history. Vaccination is the administration of antigenic material (a vaccine) to stimulate an individual’s immune system to develop adaptive immunity to a pathogen. Vaccines can prevent or ameliorate morbidity from infection. The effectiveness of vaccination has been widely studied and verified; for example‚ the influenza vaccine‚[1] the HPV vaccine‚[2] and the chicken pox vaccine.[3] Vaccination is the most

their crops. These pathogens cause great damage by wiping out whole generations of crops leaving the farmers unable to feed their families and no income. With all of these potential pathogens‚ rapid and inexpensive techniques that offer reliable resistance identification must be developed to assist breeders in their choices of what plants should be used to produce a resistant hybrid. Although there are various wild varieties of plants that are resistant to the different pathogens‚ these wild varieties

* AP IMMUNE SYSTEM * An animal must defend itself against unwelcome intruders -- the many potentially dangerous viruses‚ bacteria‚ and other pathogens it encounters in the air‚ in food‚ and in water. * Herpes simplex-1 (Herpes labialis‚ HSV-1) * Herpes simplex 2 (HSV-2‚ Herpes genitalis) on thigh * Three cooperative lines of defense have evolved to counter these threats. * Two of these are nonspecific -- that is‚ they do not distinguish one infectious agent from another

The second reason that they should fix this problem is because they can not only get cut by themselves‚ but by the person that is right next to you doing the exact same thing. For example‚ in a study executed by OSHA‚ it was said that “workers have also been cut by other workers as they remove their knives from a slab of meat. These ‘neighbor cuts’

body of an organism. There are four main types of disease: pathogenic disease‚ deficiency disease‚ hereditary disease‚ and physiological disease. Pathogenic diseases are caused by what is called a pathogen. Pathogens are parasitic organisms that cause disease in their host. For example the pathogen e.coli which can make people ill or kill them. Deficiency diseases are caused by a deficiency of a particular nutrient in the diet. A lack of vitamin c causes scurvy. Hereditary diseases are passed
