C) all cells divide to form new cells
Explain why Gram-negative bacteria are more resistant to biocides than Gram-positive bacteria. Be specific and descriptive in your response. A description of the differences between Gram-negative and Gram-positive bacteria should be included, along with an explanation of why any of those differences would have anything to do with the actions of biocides.
Explanation:
Gram positive and gram negative bacteria differ in their cell walls. gram positive bacteria have a thick peptidoglycan layer and an outer membrane protect the gram negative against many antibiotics that could otherwise damage the peptidoglycan layer or inner cell.
Immunological memory accounts for the ancient observation that someone who had recovered from the plague could safely care for those newly diseased.
Significance of plague disease
The plague is a contagious sickness that affects both animals and people. Bacteria named Yersinia pestis causes it.
- This bacteria is prevalent in rats and their fleas around the world, including in the United States.
Sunlight and drying are both effective in killing Y. pestis.
- Even yet, when discharged into the air, the bacteria may live for up to an hour, however, this might vary depending on the environment.
- Pneumonic plague is one of several types of plague. These types may occur independently or in combination, depending on the circumstances:
- When Yersinia pestis attacks the lungs, it causes pneumonic plague. This disease can spread from person to person via the air.
Transmission can occur if a person breathes in aerosolized germs, as could occur in a bioterrorist strike.
- Pneumonic plague can also be disseminated by inhaling Y. pestis suspended in respiratory droplets from a person (or animal) infected with the disease.
- In order to become infected in this manner, you must generally come into direct and personal touch with the sick person or animal.
- If a person with bubonic or septicemic plague goes untreated, the germs can migrate to the lungs and cause pneumonic plague.
The most frequent type of plague is bubonic plague.
- This happens when an infected flea bites someone or when materials contaminated with Y. pestis enter through a skin breach.
- Patients have enlarged, sensitive lymph nodes (known as buboes), as well as fever, headache, chills, and weakness.
Hence, the correct answer is option D
