Write a short letter to a friend (imaginary) who you are concerned may be using drugs. You can pick any drug of concern.

Include you suggestion regarding what steps should be taken to help this friend. Don't forget to add references to the bottom of your letter for me to review regarding any statistics you report in your submission. Pls help me, this is due today
(If you just want points and randomly say something I will report it)

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

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
