maybe 1 and 5 is the answer
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

C. glycolysis
D. et chain
E. et chain
F. Kreb's cycle
G. Kreb's cycle
H. et chain (when oxygen at the end of the chain combines with electrons/hydrogen ions)

Answer and Explanation:
This is a model of an atom. Atoms are made up of three main parts: neutrons, protons, and electrons.
Neutrons are neutrally-charged subatomic particles, protons are positively-charged subatomic particles, and electrons are negatively-charged. Neutrons and protons are always located in the nucleus of the atom, which is basically the central location. Electrons, on the other hand, orbit all around this nucleus.
In the model, the protons and neutrons should be labelled in the center big golden ball, while the electron should be labelled on the small spheres "orbiting" this big center one. The electrons should also be labelled "negatively charged". Finally, the nucleus is positively charged because it's made up of protons (which are positive) and neutrons (which have no charge).
