1. Dead plants, animal carcasses, compost.
2. You would find plenty of dead leaves and bones on the forest floor, while the desert floor would be very low in organic matter and would contain a higher majority of sand.
3. Organic matter is generally darker when referring to color. This is why the humus layer, or the final stage in the decomposition of organic waste, is black.
4. The soil texture triangle is used to help visualize and understand the meaning behind soil texture names. It tells us specifically what textures soils may be depending on the percentage of sand, silt, and clay in each.
5. The numbers on the side of the triangle relate to the percentage of clay, silt, and sand in the soil.
6. Soil compaction can prevent water drainage, slow microorganism population growth, and suffocate and stunt plants. Air can be brought back to the soil by using an aeration tool, or by introducing burrowing animals and plants with heavy roots. Aeration tools reduce compaction in soil, while rooted plants and burrowing animals create pores that allow air and water to drain into it.
7. (I can't 100% answer this question because it is apart of the reading that I don't have access to but I'll give it a shot) A soil profile is the arrangement of soil horizons that make up the various layers in the soil. We observe and describe soil horizons and soil profiles to help classify and interpret the type and uses of soils.
Answer: The answer is option D) phylum-class-order-family-species-genus
Explanation:
In taxonomy, living organisms are arranged from large to smaller categories. The complete arrangement as given by Carroleus Linnaeus is shown below
Kingdom --> phylum/division --> class --> order --> family --> genus --> species
He first split living things into a general category called KINGDOM.
- The kingdom is further split into large smaller groups called PHYLUM (for animals) and DIVISION (for plants).
- Each phylum or division is broken down into CLASSES.
- Each class is broken down into ORDERS
- Orders into FAMILIES,
- Families into GENUS
- Genus into SPECIES
His red blood cell count is low, so Gerald is feelign lightheaded and tired.

In Translation messenger RNA, is decoded in a ribosome, some outside the nucleus ,to produce a specific amino acid chain or polypeptide . the polypeptide later folds into an active protein and performs its function in the cell
