Bill and any want to ride their bikes from their neighborhood to school which is 14.4 kilometers away. it takes Amy 40 minutes to arrive at school. bill arrives 20 minutes after any. how much faster (in meters/second) is amy’s average speed for the entire trip?

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 compound light microscope is used to magnify objects in steps.
