[#76] In filarial nematode, the life cycle is
Correct Answer
(C) Indirect
Explanation
Solution: In filarial nematode, the life cycle is Indirect. Microfilariae wander through the skin, where they may be picked up by a feeding vector blackfly. In the blackfly they mature into infective larvae, which may enter a new host when the blackfly feeds. The larvae then move to the subcutaneous tissues, mature, mate, and produce microfilariae.

[#80] Cattle belongs to the phylum
Correct Answer
(A) Chordata
Explanation
Solution: Cattle belong to the phylum Chordata. All chordates possess, at some point during their larval or adult stages, five synapomorphies, or primary physical characteristics that distinguish them from all the other taxa. The name “chordate” comes from the first of these synapomorphies, the notochord, which plays a significant role in chordate structure and movement. Chordates are also bilaterally symmetric, have a coelom, possess a circulatory system, and exhibit metameric segmentation.
