Q. Define thermoregulation?
Ans. Balance the amounts of water and salts concentration is called thermoregulation.

Q. Define osmoregulation?
Ans. Internal body fluid maintaince is called osmoregulation.

Q. Write the parts of name of urinary system?
Ans. Kidney,ureter,urinary bladder,and urethra.

Q. What is hypo-tonic urine?
Ans. Excess secretion of water in urine.

Q. What is hyper-tonic?
Ans. Shortage of water in body fluid.

Q. What is meant by osmosis?
Ans. When water move from higher concentration to low concentration is called osmosis.

Q. Define hydrophytes?
Ans. Those plants which live in water

Q. Define xerophytes?
Ans. Plants live in dry condition is calles xerophytes.

Q. How plants secrete their metabolic waste?
Ans. Excrete their waste in body as a harmless substance and then convert nontoxic insoluble substance.some waste gums,resin,latex.

Q. What is homeostasis?
Ans. Maintenance of internal body condition to make at equilibrium state.

Q. What is excretion?
Ans. Elimination of waste material is called excretion.

Q. What is meant by pressure filtration?
Ans. Blood enter the kidney through renal artery then go glomerulus so pressure of blood is high and water salts glucose urea of blood more pressurize the glomeruler.

Q. What is the size and weight of human kidney?
Ans. Each kidney is 10cm long,5cm wide and 4cm thick and weight about 27 grams.

Q. What role is played by lungs in homeostasis?
Ans. Lungs maintain the concentration of carbon dioxide in blood.carbon dioxide produce they perform cellular respiration.

Q. What is kidney failure?
Ans. When kidney does not perform its function properly.it lead to kidney failure.

Q. Name the metabolic wastes produced in conifers and keekar tree?
Ans. Conifers Resins  Ans. Keekar Gums.

Q. What is lithotripsy?
Ans. Removal of stones in kidney.In which non electrical technique use and waves falls on stone from outside of the body.

Q. What is tissue rejection?
Ans. When tissue protein not match they reject the kidney.

Q. Define dialysis?
Ans. Artificial cleaning of blood

Q. Define Guttation?
Ans. Drops of water present on the upper surface of leaves is called guttation.
