Meningitis is the inflammation of the protective covering of the meninges, the three membranes covering the brain and spinal cord. Meningitis usually occurs from a viral infection, but may sometimes result from a bacterial or fungal infection, cancer or drug allergies.
Viral and bacterial meningitis may be contagious and can be transmitted through coughing and sneezing.
Symptoms of meningitis include:
- sensitivity to bright light
Treatment is by vaccination, use of antibiotics and antifungal agents.
Answer:
C
Explanation:
I think its C . A transcriptional repressor usually represses the transcription pathway when its active. According to the question, the repressor is not usually active until an effector molecule binds to it making it active and blocking the transcription pathway. So if the region where the effector binds on the repressor is mutated i.e. it turns nonfunctional that means the effector cannot bind to repressor which means repressor cannot become active to block transcription which in turn increases the transcription of gene A because repressor cannot repress it since it is inactive due to its inability to bind to the effector.
ALOT of words please lmk if it makes sense
They pollinate plants, which saves farmers work. Insects such as bees and butterflies help to pollinate plants.
