Answer:
question 2 answer
Explanation:
if platelets not have in human clotting factor is absent due to absence of platelets and after injury blood will not stop because of absence of platelets
Multicellular organisms are coelomates their body is designed in a complex pattern hence they require specialorgans.
A reason is that multicellular organisms need special organs for exchange of gases with the environment because of prokaryotic cells found in the body. The cells are not in contact with the environmentand therefore diffusion would not work in the exchange of gases.
