-you are not using paper cups which results in less trees being cut down which provides more filtered oxygen for us to breath.

- You can recycle plastic so less of it is used. Plastic takes a while to deteriorate in the Earth so using less of it is good for the planet.

-Plastic is very easy to clean and doesn't usually make stains that cannot be cleaned.

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
