Si Se Sumerge En Un Vaso De Agua Una Piedra, Un Bolígrafo Y Un Tajalapiz. ¿Que Sucede?.

Al introducir una piedra en agua, está se va al fondo del vaso, por que es más pesada que el agua

Al introducir un bolígrafo, este flota, por que es más liviano que el agua

Si se introduce en agua un tajalapiz se evidenciará un proceso de corrosión del metal

Debido a la reacción con el agua, sin embargo el efecto será más evidente si se agrega sal a la mezcla

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
