Answer:
The correct answer will be option-B.
Explanation:
Sertoli cells are the large somatic cells present in the testis which helps in the formation of spermatozoa. The Sertoli cells create a suitable environment for the production and maturation of the sperms as they produce certain molecules which nourishes the sperms.
The Sertoli cells act as a barrier between the testis and blood and secrete enzymes like inhibin. They eliminate the apoptotic germ cells and also produce seminiferous fluid to nourish the sperm. They do not play any role in primary spermatocytes.
Thus, Option-B is the correct answer.
Canada, one of the wealthiest countries in the world, is also one of the most water-rich. The province of Ontario shares the Great Lakes—which contain 18 percent of the world’s fresh surface water—with the United States. Access to sufficient, affordable, and safe drinking water and adequate sanitation is easy for most Canadians. But this is not true for many First Nations indigenous persons. In stark contrast, the water supplied to many First Nations communities on lands known as reserves is contaminated, hard to access, or at risk due to faulty treatment systems. The government regulates water quality for off-reserve communities, but has no binding regulations for water on First Nations reserves.

It is very hard to see what is going on.
The most significant limitation to the clinical utility of anthracycline antineoplastic medicines, which include doxorubicin (adriamycin), daunorubicin, or epirubicin, is the danger of cardiotoxicity.
- Nevertheless, these substances continue to rank among the most popular anticancer medications.
- Although the oxidative stress-based concept involving intramyocardial formation of reactive oxygen species (ROS) has acquired the most respect, the molecular etiology of anthracycline cardiotoxicity is still quite debatable.
- Through redox cycling of both their aglycones and anthracycline-iron complexes, anthracyclines may facilitate the generation of ROS.
- Given the remarkable cardioprotective efficacy of dexrazoxane, this suggested mechanism has gained a lot of traction (ICRF-187).
What is Influenza?
- It affects the lungs, nose, and throat.
- High-risk groups include young children, elderly individuals, pregnant women, persons with chronic illnesses, and those with weakened immune systems.
- Fever, chills, muscle pains, cough, congestion, runny nose, headaches, and exhaustion are some of the symptoms.
- Rest and fluids are the main treatments for the flu because they allow the body to fight the illness on its own.
- Anti-inflammatory painkillers sold over-the-counter may aid with symptoms. An yearly flu shot can lessen complications and aid in prevention.
