The tendency of biological systems to resist change

The tendency of biological systems to change with change in environment

Disturbance of self-regulatory system and natural controls

Match the items of column I with those of column II: Column I Column II a) Ammonotelism (i) Birds b) Bowman's capsule (ii) Water reabsorption c) Micturition (iii) Bony fish d) Uricotelism (iv) Urinary bladder e) ADH (v) Renal tubule

(a)- (iii) Ammonotelism is the process of excretion of ammonia as an excretory product. Ammonia is highly toxic, so the organism needs plenty of water to make it less toxic. That is why aquatic organisms like bony fishes, octopus excrete ammonia and are called as ammonotelic organism. (b)- (v) Bowman's capsule and renal tubule are the part of nephron of the kidney. (c)- (iv) Micturition is the action of urination where urine is released out from urinary bladder through the urethra. (d)- (i) Uricotelism is the process of excreting uric acid. It is a highly concentrated compound released by organisms who live in water deficit region and the example of these type of organisms are birds. (e)- (ii) ADH is a hormone secreted from posterior pituitary. It helps in reabsorption of water from DCT and CT (collecting tubule) of nephron.
