Why is the Lancelet a chordate, but not a vertebrate?
nika2105 [10]

Lancelet is a chordate but not a vertebrate because it lacks a backbone

Explanation:

The subphyla of the phylum Chordata are - Vertebrata, Urochordata and cephalochordate

Those chordates with a structural backbone belong to Vertebrata.

Urochordates and cephalochordates lack a backbone and hence are termed invertebrate chordates.

Lancelet is an invertebrate chordate of the subphylum – Cephalochordata.  

The lancelets consist of a notochord that extends right from the head till the tail at the dorsal surface. The notochord acts like the backbone and provides support and a semi-flexible structure to aid in the movement of the organism.

They lack a developed nervous system like vertebrates but only has a dorsal nerve tube .

Thepotemich [5.8K]

Answer:

Avirulent.

Explanation:

VIRULENCE is the ability of a pathogenic organism  to infects the host, leading to damages  or death of the host. The extent of these virulent effect depends on  certain chemical substances ( called Virulence factors) produced during the  pathogenic processes.

The virulence effects  is achieved  due to the ability of the virulent factor to disrupt the entire physiological mechanisms of  the organisms; e,g crop plants; though  suppression of the host immune response, disruptions of the immune mechanisms, colonization of the host DNA structure etc. Therefore the pathogenic effects suppressed the host resistance and spread throughout the host body system.

In this present scenario, the pathogenic effect of the likable bacteria; is not virulent, because

none of the d crop pant is completely diseased.

the nascent intenodes and leaves  are growing to usual size.

Consequently, the physiological and the morphological features of the crop plants are still intact. Thus the infection is AVIRULENT.
