Locard’s exchange principle is best described as
a) no two pieces of evidence have any similar markings
b) a scientific experiment has been generally accepted by experts
c) evidence at a crime scene should be replaced with evidence from the victim’s home
d) there is a transfer of evidence when two objects come into contact with each other.

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
