This causes it to reproduce blue colonies of bacteria. 5. We did not add plasmid to the control plate because it did not have any bacteria on it to cause a reaction. 6. We put the bacteria through a heat shock because that is how hot it would be in a human body, therefore, making it a natural
Hand gels should only be used as an interim measure until you are able to perform a proper hand wash; they are not a suitable replacement for good hand washing. Uniforms must be kept clean and tidy, and I wear a clean uniform every day. Tunics should have short sleeves to prevent them from dragging in body fluids when undertaking moving and positioning procedures. I must not go to the shops in my uniform, because I could be spreading bacteria and infectious agents. Personal hygiene is also important in the fight against infection.
I also need to dispose of hazardous substances correctly and not mix substances in case of any hazardous fumes or explosions that may occur. I must also never decant chemicals to unlabelled or wrongly labelled containers. To prevent any accidents or incidents happening with hazardous substances I must ensure I follow the data sheets and follow instructions. I must wear the PPE (personal protective equipment) when using substances to avoid cross contamination and accidents. I must also report any defects or ill health that may happen.
| | | A) | endoplastic reticulum | | | B) | microtubules | | | C) | cytoplasm | | | D) | mitochondria | | | | | | Feedback: The cell's chemical processes take place in a semifluid material called the cytoplasm. This material provides an ideal environment for organelles because of its fluidity. | | 7 CORRECT | | This shows an example of endoplasmic reticulum. What is the significance of its structure? | | | A) | provides a location for DNA production | | | B) | helps decrease surface area | | | C) | allows selective permeability of cell membrane | | | D) | facilitates breakdown of chemical bonds | | | | | | Feedback: The pleats and folds of the endoplasmic reticulum provides a large surface area where cellular functions, such as breaking chemical bonds, can take place.
He was now certain that there were no live germs in the flasks. All the flasks were allowed to cool. As long as they were not shaken or tipped up, the liquid did not go bad. The necks of some flasks were broken so allowing the air to carry dust into them. The experiment was repeated with many flasks under many different conditions.
It reduces them to a level which is considered safe and not harmful to health however is may not necessarily destroy some viruses. Disinfection should not be used as a substitute for sterilization as it will not achieve the same reduction in microorganisms as sterilization will. Sterilization- Sterilization renders an object free from viable microorganisms, including viruses and bacterial spores. Sterilization can be achieved by steam, hot air, ethylene oxide or irradiation. Autoclaving is the most common method, it uses steam under pressure to sterilize instruments and is the most reliable method.
Mercury thermometers should not be thrown in the trash because mercury is toxic. Reference: p.522. Question 2: Which of the following is an accurate guideline to follow when assessing blood pressure using a Doppler ultrasound? You selected: If using a mercury manometer, check to see that the manometer is in the horizontal position and that the mercury is within the zero level. Correct response: Center the bladder of the cuff over the artery, lining up the artery marker on the cuff with the artery.
In this case, I believe the government took it too far because there was no warrant allowing officers to scan DLK’s home, there was no danger of losing evidence, and DLK’s fourth amendment rights were violated. First of all, using the thermal scanner in this case is considered a legal search and the officers that used it were not given a warrant. On a warrant, there are three major parts; who is being searched, where they are searching, and what is being searched for. Since officers knew who and what exactly they were searching for at DLK’s home, a warrant should have been provided. Obviously, heat radiation cannot be seen without some type of tool.
Unit 4223-031 Outcome 1 Understand how to maintain a clean environment to prevent the spread of infection. 1. State the general principles for environmental cleaning. The work environment should clean dry and germ free. Dust, dirt and liquid substances must not be allowed to build up.
Prioritizing means that one particular situation is the only one in concern before all other situations. Prioritizing poverty means forgetting about HIV/Aids, diabetes, but more importantly environmental protection. That comes to our definition of protection. Protecting ourselves from something means we are only doing things to help prevent something bad from happening. It does not mean we are eliminating the situation.
