C. E.coli

D. Monkey

Answer 1

Here , correct option is: (B) C.elegans

[In C. elegans, a protein in the outer mitochondrial membrane, called Ced-9 (the product of the ced-9 gene), serves as a master regulator of apoptosis. When a death signal is received by the cell, it overrides the brake, and the apoptotic pathway activates proteases and nucleases, enzymes that cut up the protein and DNA of the cell. The main proteases of apoptosis are called caspases; in the nematode, the chief caspase is Ced-3.]
