The urinary system is made up of the kidneys, bladder and ureters (tubes that connect the kidneys to the bladder). The kidneys act as filters removing extra fluid and waste from your blood to make urine. Urine passes from the kidneys into the ureters, which drain into the bladder. When the bladder is full, urine flows out of the body through a tube called the urethra.
The ureters normally enter the bladder at a diagonal angle and have a special one-way valve system that prevents urine from flowing back up the ureters in the direction of the kidneys. If this system doesn’t work, urine can flow back towards the kidneys. This is called vesicoureteric reflux (also known as urinary reflux).
Sometimes vesicoureteric reflux (VUR) can be associated with other 'plumbing' problems in the urinary tract and with small, damaged or malformed kidneys.
So I believe the answer is 1.
Answer: Fungi are microscopic heterotrophic living organisms that grow as long threads called hyphae. In terms of their function, they can be divided into-
Parasitic fungus that obtains nutrients from living host while harming it, mutualistic fungus that obtains nutrients and inturn provides benefit provides to the host, and saprophytic fungus that are mainly classified as decomposers.
Thus, correct match is as-
A) Parasitic fungus- 4) lives within the blood of another organism and causes disease
B) Mutualistic fungus - 5) lives around the roots of a tree and provides nutrients to the tree
C) Saprophytic fungus- 2) lives in a marsh environment and aids in biodegradation.
