(ii) What is your observation after a few hours for flask A’ and ‘B’ ?
(iii) Name the chemical uged to prevent bacterial growth.
Explain how the bacteria would interfere with the experiment.

(v) Which is the control set-up and why ?
Answer:
(a) (i) To show that heat is liberated by respiration process from germinating seeds.

ICSE Class 9 Biology Sample Question Paper 1 with Answers

(ii) In flask A, as seeds are germinating so they undergo respiration and heat is evolved which is marked by rise in mercury level of thermometer. But in flask B as seeds are dead, so no respiration and thus no heat is produced. So mercury level in thermometer will not rise.

(iii) Carbolic acid : Bacteria will undergo respiration and will produce heat that will cause rise in level of mercury of thermometer. Thus, the bacterial growth may interfere with results of the experiment.

(iv) Thermos flask acts as an insulator, so it does not allow outside environmental temperature to interfere with the results of the experiment.

(v) Flask B is a control set-up as seeds are dead, so there is no respiration hence no production of heat.

(iii) Nostrils contain fine hairs which trap large foreign particles present in air and prevent them from entering into our body. Nasal chamber secretes mucous which entraps harmful particles like dust, germs thus allowing pure and germ free air entering into our respiratory tract. It also warms and moistens the air. Thus, we should breathe through nose and not through mouth.

(iv) The C-shaped cartilaginous rings provide strength and flexibility to the walls of trachea and keep the trachea in distended condition permanently without collapsing the windpipe.

(v) Two activities of WHO are :
