A researcher performed an experiment during vulva formation in C.elegans;

I- In first experiment destroyed anchor cell 

II- In second experiment destroyed three central VPCs 

What kind of conclusion has been drawn by these experiments?

a) I-Three cells out of six of the equivalence group divide once and contribute to the vulva formation

b) I-all six cells of the equivalence group divide once and contribute to the hypodermal tissue

c) II-three outer cells, which normally form hypodermis, generate vulval cells instead

d) II-three remaining cells normally formed hypodermis as usually

Biosensor is a sensing device. It senses biomolecules by sensing

1. The interaction produces some detectable physical change that is measured and converted into an electrical signal

2. The interaction produces some detectable physical change that is measured and converted into ions.
