What is the difference between a coroner and a medical examiner? where does the term coroner come from?

The correct answer would be - their selection process and their professional status.

Explanation:

A medical examiner is someone that performs an autopsy on the other hand coroner does not perform it. The medical examiner needs to be a forensic pathologist while coroner does not require such qualification.

The major differences that differentiate the medical examiner and coroner are their selection process and their status professionally. Medical examiners have required a board certification in a medical specialty while coroners are elected and not required any professional training.

Coroner term comes from the Anglo-Norman coroner, which is derived from the corouner or "crown."  

Thus, the correct answer is - their selection process and their professional status.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
