"the thickness and of soil are key factors in determining site suitability for a septic system."

The key factors are the thickness and the type of the soil.

What should be done is the study of the stratigraphic sections of the receiving ground (profile and thickness of the different soil layers of the natural terrain, rock profile and average maximum groundwater level, soil types: texture, structure, density, color, presence traces of oxidation-reduction, associated level of permeability, presence of organic matter, etc.).

The report should describe the classification system used to describe soils.

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
