Which event is an example of genetic drift? an earthquake kills 90 percent of the green beetles in a population of green, black, and brown beetles. a green beetle travels from its population into a new population of entirely black and brown beetles. green beetles have better camouflage than brown or black beetles and are not eaten as often. warm temperatures cause green, black, and brown beetles to start reproducing earlier than normal.

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
