Statement A : Notochord is persistent only at larval stage, after that it diappearsin urochordates Statement B : Insects blood has no role in transport of oxygen
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Notochord is persistent only at larval stage, after that it diappearsin urochordates is correct. Hemolymph, is a fluid, analogous to the blood in vertebrates, which circulates in the interior of the arthropod body remaining in direct contact with the animal's tissues. It contains hemocyanin, a copper-based protein that turns blue in colour when oxygenated, instead of the iron-based haemoglobin in red blood cells found in vertebrates, thus giving hemolymph a blue-green colour rather than the red colour of vertebrate blood.

Assertion : Branchiostoma belong to sub phylum cephalochordata. Reason : Notochord extends from head to tail region and is persistent throughout their life.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
Explanation:
When notochord extends from head to tail region and is persistent throughout their life, organism belongs to subphylum Cephalochordata. Examples are Branchiostoma.
