Why are tears and saliva potential biohazards?
Expert Solution & Answer
Summary Introduction
To analyze:
Tears and saliva potential biohazards.
Introduction:
Biohazard is any substance of biological origin posing an intense threat to living beings and their health. It can be bacteria, viruses, a bio-toxin, infected body fluids medical wastes, etc.
Explanation of Solution
Body fluids like blood, saliva, semen, vaginal fluids, mucus, transport nutrients to the cells and expel wastes out of the body. Saliva that is produced by the salivary gland contains glycoproteins and minerals. It becomes a biohazard if it is infected with deadly microbes. There are many levels of biohazards amongst which Biohazard level 2 are agents that pose severe illness that gets transmitted through direct exposure to the infected fluid. For instance, Hepatitis B gets transmitted through infected blood, saliva, semen, etc.
Tears and saliva are not potentially infectious materials unless contaminated with blood or other OPIM (Other Potentially Infectious Materials) like body fluids, unfixed tissue or organ from a live or dead human, Infected cell or tissue cultures.
Conclusion
Hence, the body fluids with infection are major biohazards if transmitted.

13. Practice Calculations: 3 colonies were suspended in the following dilution series and then a
viable plate count and microscope count was performed. Calculate IDF's, TDF's and then
calculate the CFU/mL in each tube by both methods. Finally calculate the cells in 1 colony by
both methods. Show all of your calculations in the space provided on the following pages.

- You have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forwardUse the following tree diagram to answer Questions #8-10. 8) Which of the following two animals are the most closely related based on the tree to the left? a) Pig and camel b) Hippo and pig c) Deer and cow 9) CIRCLE on the tree diagram where the common ancestor between a hippo and a cow is. 10) Put a SQUARE on the tree diagram where the common ancestor between a pig and a peccary is.arrow_forwardExplain: Healthy Cell Function Overview→ Briefly describe how a healthy cell usually works: metabolism (ATP production), pH balance, glycogen storage, ion transport, enzymes, etc. Gene Mutation and Genetics Part→ Focus on the autosomal recessive mutation and explain: How gene mutation affects the cell.
