Answer:
a. generated during bacterial infections
Explanation:
Free radicals are atoms with an unpaired electron which make them highly reactive. Many of these are necessary for life, such as the intracellular killing of bacteria by phagocytic cells such as granulocytes and macrophages
If this is a true or false question then this will be true
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

Answer:
The proximate explanation for this fixed action pattern might be that nudging and rolling released by the sign stimulus of an object outside the nest, and the behavior is carried to completion once initiated. The ultimate explanation might be that ensuring that eggs remain the nest increased the chance of producing health offspring.
Hello,
The answer should be "sound waves".
Reason:
If a gun go off the sound waves can go through anything to allow the person to hear for example: the sound wave can go through walls, water, and hard surface. It can also allow you to hear something but not see it therefore the answer is sound wave!
If you need anymore help feel free to ask me!
