Statement 1 : Cephalochordata bears noto chord all along the body throughout life. Statement 2 : Urochordate bears vertebral column only in tail region throughout the life. Which statement is correct?
1 Both $1^{\text {st }}$ and $2^{\text {nd }}$ are correct
4 Both $1^{\text {st }}$ and $2^{\text {nd }}$ are wrong
Explanation:
B Cephalochordates and vertebrates have a hollow dorsal nerve cord, pharyngeal gill slits and notochord . - Cephalochordates have notochord all along the body throughout the life. - The notochord is retained into adulthood and is never replaced by vertebrae. - Urochordates have notochord in the tail region in their larval stage only.

The protochordate that doesn't have heart, respiratory pigment, blood corpuscles but performs respiration through the external body surface is
1 Oikopleura
2 Doliolum
3 Branchiostoma
4 Pyrosoma
Explanation:
C Branchiostoma is a lancelet, a type of choradata that is closely related to vertebrates. It has a notochord, a dorsal hollow nerve chord, and pharyngeal slits. However, it does not have heart respiratory pigment, or blood corpuscles. It respires through its external body surface.

The outermost covering of the egg of housefly is
1 chitin
2 chorion
3 vitelline membrane
4 plasma membrane
Explanation:
B The hard outer covering of the egg of housefly is known as chorion. The chorion is made up of chitin, a strong, flexible material that is also found in the exoskeleton of insects.

Solenocytes are associated with
1 respiration
2 digestion
3 excretion
4 nutrition
Explanation:
C Solenocytes are flagellated cells involved with excretion, ion regulation and osmoregulation in some chordates which belongs to the subphylum Cephalochordata. It is a cup shaped cell that includes group of cilia and this is the main excretory organ of platyhelminthes. In lower vertebrates solenocytes removes the nitrogenous wastes.
