Just below the O horizon is “topsoil” or “A” horizon.
Usually it is darker than the lower layers, loose and crumbly with varying amounts or organic matter. Plants roots, bacteria, fungi, and small animals are abundant here, and plants thrive in it. It is generally the most productive layer of soil.

Matching questions match each description with the appropriate phase of mitosis:
strojnjashka [21]
Hello!!
A: Anaphase — 1 chromatids move towards opposite poles. I always remember that “Ana” moves to different places on the sides of town. This is where the chromatids begin to move.
B: Telophase — 4 Cytokinesis may occur. Cytokinesis is the last and final step. The sister chromatids finish moving towards the poles and then cytokinesis occurs.
C: Metaphase — 3 Chromatids line up in the middle of the cell. I always remember since they line up in the middle, they “met” there.
D: Prophase — 2 and 5 Disintegration of the nuclear membrane and the spindle forms. Both of these have to happen first in order for the rest of the processes to occur.
**The order of mitosis goes prophase, prometaphase, Metaphase, Anaphase, Telophase, and Cytokinesis.**
For the bottom:
A: Algae 6 and 10. Both diatoms and kelps (plant related) are a part of the Algae general type.
B: Fungi 7 and 9. Deuteromycetes and Ascomycetes.
C: Protozoa 8. It is ciliates because they are a major group of Protozoa from cilia.
I hope I helped!! Have a great day!! :)

What are Advantages of Natural resources.​
trasher [3.6K]

☁️ Answer ☁️

In the natural ecology, all kinds of natural flora and fauna grow automatically.

One of the main benefits of natural resources is the provision of energy that is used to drive machinery, vehicles and even airplanes. In fact, most of the moving objects, including sheep would not move without the energy from natural resources. Crude oil is one of the main sources of this energy.

Hope it helps.

Have a nice day!~  ̄▽ ̄❤️
