Answer: E- Primary Layer
Explanation:
The definition of the Primary Layer, AKA Top soil, literally means the top layer of soil. This translates directly to the layer of soil with minerals and organic material.
The A horizon in the soil profile is the layer that contains a mixture of minerals and organic material. Part of this organic material is humus, which enriches the soil with nutrients, making it fertile for plant growth.
In the context of soil profile, the A horizon is the layer that is a mixture of organic material and minerals. This includes the inorganic material of soil, which is made up of rock that has slowly degraded into smaller particles that vary in size, known as sand, silt, and loam. The organic matter that is mixed within this horizon is known as humus. Humus, which comprises microorganisms both dead and alive, as well as decomposing animals and plants, contributes greatly to improving the soil structure by providing plants with water and minerals. Therefore, the answer to your question is b) A horizon.

in general, areas on earth that are dominated by subtropical high-pressure cells are often rain forests.
The subtropical ridge, more recognized as the subtropical high or horse measures, is a vital belt of evocative high influence situated nearby the ranges of 30°N in the Northern Hemisphere and 30°S in the South Hemisphere. It is the outcome of the global atmospheric rotation cell identified as the Hadley Cell.

Answer: B. Natural Gas
Explanation:
Natural gas is the cleanest-burning fossil fuel as it primarily emits just carbon dioxide and water vapor when burnt. It is cleaner than petroleum, oil, and coal.
The cleanest-burning fossil fuel is B. natural gas. This is because natural gas is a hydrocarbon gas mixture primarily composed of methane. When natural gas is burned, it produces mostly carbon dioxide and water vapor. These are the same compounds that we exhale when breathing. Compared to other fossil fuels like petroleum, oil, and coal, natural gas releases a lesser amount of harmful emissions and pollutants, thus making it the cleanest-burning fossil fuel.

herb zone - short plants
b.
tree stratum zone - trees between 60-100 feet tall
c.
small tree and sapling zone - young and short trees
d.
ground zone - grasses
D)ground zone - grasses.
The most appropriate grass type for zones 1 and a couple of are bluegrasses. No other common lawn grasses will live on in those extraordinarily cold areas. Bluegrassseeds are first-rate planted in February thru may also, or September via November to create a low-protection, medium- to high-quality-textured garden.
Purple muhly grass is one of the easiest decorativegrasses to care for. This taller plant grows to about three toes and makes an exciting show, in particular near the quit of summer. As the season draws to a close, the deep inexperienced leaves produce smooth crimson plantlife that supply off a fuzzylook.
