Answer:
Boiling water and alcohol
Explanation:
Nowadays we know that we can never disinfect completely a syringe, so that is why we don't do it and we use a new one every time.
Although the best way to disinfect a syringe may be the following method:
- Disinfect the syringe using sterile cotton balls soaked in 70% alcohol. Rub all the surface of the syringe with the cotton until you feel that the alcohol covered everything. This will kill most bacteria but not everything.
- Sterilize the syringe using an autoclave machine. An autoclave machine is nothing but a special pressure pot that uses steam pressure and heat to kill most of the organisms, except spores and heat-resistant bacteria.
- Just to help more the probabilities of killing the most part of microorganisms, repeat the step number one. Use alcohol after taking out the syringe from the autoclave.
- Use the syringe right away or it will get infected again in a matter of seconds.
There are different types of biases in a survey sampling. This includes: under coverage, nonresponse bias, response bias, voluntary response bias, etc.
A.- 2.
B. - 3.
C. - 1.
A. Under-coverage - 2. Few chosen representatives are not good sample for that project. Thus, not a representative sample.
B. Response bias - When there is expectation of a selected answer. Thus, expecting a certain answer.
C. Question-wording bias - 1. The wordings in an answer is false or inappropriately put together. Thus, Answer given do not reflect true views.
