Question 4 Leave the rocks submerged in the jars for about 90 minutes. Then use a spoon to carefully scoop the rocks from the jar
labeled 0% Acid. Dry the rocks by patting, or blotting, them with a soft rag. After the rocks are dry, measure their mass and
record it on the sticky note. Use this format: "Final Mass:." Place the jar with the liquid on the counter and place the
dried rocks next to the jar. Repeat this process for the other three jars. After you have recorded the final mass for each
jar, complete this table.

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
