A.
leptospirosis and bilharzia
Leptospirosis (also known as Weil's disease, canicola fever, canefield fever, nanukayami fever or 7-day fever) is a bacterial zoonotic disease caused by spirochaetes of the genus Leptospira that affects humans and a wide range of animals, including mammals, birds, amphibians. and reptiles. It was first described by Adolf Weil in 1886 when he reported an "acute infectious disease with enlargement of spleen, jaundice and nephritis. Humans become infected through contact with water, food, or soil containing urine from these infected animals. This may happen by swallowing contaminated food or water or through skin contact.
Leptospirosis is common among watersport enthusiasts in certain areas as prolonged immersion in water is known to promote the entry of the bacteria Schistosomiasis or bilharzia is also called snail fever or swimmer's itch.
Schistosomiasis is a life threatening parasitic disease caused by a worm that lives in a host snail. Humans can become infected when they come in contac with water in ponds and rivers where the snail lives. The pathology is mostly caused by the large number of eggs becoming stuck in various body parts, in particular the liver (causing liver enlargement and malfunction) and the kidneys (causing kidney damage, detectable by blood in the urine).
The main reason why antibiotics could not solve all the problems of bacteria mediated diseases is
insensitivity of the individual following prolonged exposure to antibiotics
inactivation of antibiotics by bacterial enzymes
decreased efficiency of the immune system
the development of mutant strains resistant to antibiotics.

The binding of antibodies to the antigens to produce a large insoluble complex is known as
antibody-antigen complex
agglutination
immunisation
suppressor cell reaction.
Assertion: Hybridoma cells are shifted to a medium deficient in nutrient which cannot be synthesized by myeloma cells.
Reason: This medium allows selection of hybridoma cells.
If both assertion and reason are true and reason is the correct explanation of assertion
If both assertion and reason are true but reason is not the correct explanation of assertion
If assertion is true but reason is false
If both assertion and reason are false.
When a man inhales air containing normal concentration of O2 as well as CO he suffers from suffocation because
CO reacts with O2 reducing its percentage in air
haemoglobin combines with CO instead of O2 and forms carboxyhaemoglobin
CO affects diaphragm and intercostal muscle
CO affects the nerves of the lungs.
