Based on the macroscopic views of the three substances, which is most permeable? gravel sand silt impossible to tell

Gravel

Explanation:

Gravel is a material that has high permeability. Gravel is widely used as a material for paving, because it is a material of lower cost offering savings for construction, for this reason, it is easily found in parking lots, bicycle paths, sidewalks, among others. Its permeability allows that when a liquid reaches it, it can drain through the gravel pores very easily.

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

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.

can i get the brainliest pls
