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 .

Cathy placed a sample of yeast , a single celled eukaryotes, in a closed test tube containing a solution of glucose. How will th
maxonik [38]
Yeast is very similar to human cells in that we have the same cellular respiration process. The formula for cellular respiration is C6H12O6(Glucose) + O2(Oxygen) = CO2(Carbon dioxide) + H2O
Because of this we know that the yeast is going to take oxygen from the air and the glucose in the test tube and produce carbon dioxide with it, so the full answer would be “The composition of the air in the test tube would change so that there is a higher composition of CO2.” If you need to explain it more pull from my explanation :)
