Answer: a. too much acetylcholine staying in the neuromuscular junction for too long
Explanation:
Sarin is a gaseous organophosphate. This gas is used for chemical warfare. This affects the nervous system of the body. The gas if inhaled can cause death within minutes.
Acetylcholine is a neurotransmitter molecule. It is released from the pre-synaptic neurons that binds to the acetylcholine receptors.
The gas sarin will target the enzyme acetylcholinesterase present in the neuromuscular junction of the body where the nerves actually meet the muscles. The enzyme degrades nerve signaling molecule acetylcholine. Thus when the sarin degrades the enzyme the levels of acetylcholine will rise up in the blood. The acetylcholine remain in the neuromuscular junction. The acetylcholine will stimulate the nerve cell receptors. Excess of acetylcholine will cause excessive twitching and may lead to paralysis.
Answer: Difference between presumptive test and confirmation test
Explanation:
A presumption test or screening is a test to detect diseases in early stages and shows the prevalence of a disease in the population, it is performed in asymptomatic people, which is classified as having or not having the disease that is sought, the objective of these tests are to reduce morbidity-mortality in the study population, confirmatory tests or diagnostic tests are those that confirm or rule out the disease and are performed after a screening test, an example is HIV-AIDS tests, in which the screening test is performed on the population with risky sexual contacts called the rapid test, ELISA and if it is positive, the Western Blot confirmation test is performed.
Answer:
Trigger the production of anti-bodies.
Explanation:
Antigens are the substances, may be virus, bacteria, fungi which can cause infection. In response to this, Antibodies are produced stimulated by immune system.
For e.g. if a blood group of person is A, the cells contain A antigen on it. So it having anti-B antibodies.
