(a) part which separates chest cavity from abdominal cavity (b) balloon like structures where exchange of gases takes place. (c) part where air is filtered by fine hair and mucus.
(d) part which terminates in balloon like structures.
(c) Write its balanced chemical equation.
(1+1+1)
(ii) “Rate of breathing in aquatic organisms is much faster than in terrestrial organisms”. Justify.

Answer 1

(A) Diaphragm

(B) Alveoli

(C) Nasal cavity.

(D) Bronchioles

C

(ii)The amount of dissolved oxygen in water is fairly low compared to the amount of oxygen in the air. Therefore, rate of breathing in aquatic organisms is much faster than in terrestrial organisms.

Answer 2

Answer:

a diaphragm

b alveoli

c nose

d bronchitis

the rate of breathing in aquatic organisms much faster than in terrestrial organisms due to less amount of oxygen is present in water as water is H2O and the amount dissolved in H2O of oxygen is less that's why they required a lot of water to get oxygen oxygen for their gills that's why they respiration is more faster than terrestrial organisms
