D identity disorder is characterized by the presence of two or more distinct personality identities. Each may have a unique name, personal history, and characteristics.
So other scientists can try the exact same experiment and see if they both got the same results.
La hepatitis B es un virus, una infección de su hígado. Puede causar cicatrización del órgano, insuficiencia hepática y cáncer.
I think the answer is D but it's been a while since I've done this.
