Give reasons for the following: a) Presence of cartilaginous rings in trachea. b) Small intestine in herbivores is longer than in carnivores. c) What will happen if platelets were absent in the blood?
Answers
Answer:
a) : Rings of cartilage are present in the trachea because it provide flexibility and support to the trachea permitting it to move it and flex when breathing. ... These rings stabilise the trachea and make it rigid while permitting it to "expand in length" when the person breathes.
b) The small intestine is longer in herbivore than in carnivore because herbivores eat only grass which is full of cellulose and the digestion of cellulose takes a long time.
c) The blood platelets are required for the process of blood clotting. Whenever there is an injury, to prevent the loss of blood it is necessary to form a clot. ... If there are no platelets, there will be no clot formation. This might result in haemorrhage in which there is continuous blood loss.
Explanation:
Mark me as a brainliest
a= to support the trachea
b= because herbivores have to digest cellulose
c= platlets are responsible for blood cloting if its absent in blood delay blood clot and excessive blood loss occure
I hope this is helpfull for u
