It is only found in topsoil (not sure abt this tho)
Humus forms from dead plants, fertilizes soil, contains carbon, and is only found in topsoil. The correct options are A, C, D, and E.
What is humus?When plant and animal debris decomposes in the soil, humus, a black, organic substance, is created.
Plants scatter leaves, twigs, and other debris to the ground, which accumulates. Leaf litter is the name of this substance. Animal carcasses contribute to the litter after they pass away.
Humus is a form of soil produced by decomposing organisms and plants.
The name was developed by a French soil expert named Muller and is based on the Latin word "soil". Humus is challenging to define and is still not completely understood.
Only found in topsoil, humus is a material that develops from dead plants, fertilizes the soil, and contains carbon.
Thus, the correct options are A, C, D, and E.

what is the essence of recognizing the different species of organism in our country 1 paragraph pls
Answers
Answer:
To maintain equilibrium.
Explanation:
The essence of recognizing the different species of organism is very important in our country because we can avoid certain activities that leads to the extinction of that species. Recognizing the nature of a specie is necessary in order to provide good and suitable environmental conditions to the organisms and avoid those activities due to which its growth is negatively affected and leads to removal of that specie from ecosystem so that's we can say that the essence of recognizing the different species of organism is very important to maintain equilibrium in the ecosystem.

Discuss the orogenies that produced the Appalachian Mountain Range. Include in your answer the timing, process, and resultant sedimentation patterns. Include additional Paleozoic orogenic events to strengthen your answer if need be.
Answers
Answer:
Explanation:
Appalachian orogenic belt, an old mountain range that extends for more than 3,000 km (1,860 miles) along the eastern margin of North America from Alabama in the southern United States to Newfoundland, Canada, in the north. The geosynclinal theory of mountain building was first worked out in the Appalachians by James Dana and James Hall in the late 19th century; today a plate tectonic theory is invoked. The earliest Appalachian sediments were deposited near the start of the Cambrian Period (542 million years ago) on the shores of the opening Iapetus Ocean. Subduction of the Iapetus led to its destruction and the collision of different continental blocks and island arcs. Those collisions gave rise to three Appalachian orogenies: the Taconic in the Middle Ordovician (about 472 million years ago); the Acadian in the Middle to Late Devonian (at 390 million to 370 million years); and the Alleghenian in the Late Carboniferous to Permian (300 million to 250 million years ago). The age of these orogenies decreases eastward across the orogenic belt, demonstrating that it was formed by the progressive eastward addition of arcs and continental fragments to the continental margin of North America. The Appalachian belt continues to the east in the form of the Caledonian and Hercynian orogenic belts in western Europe. The Alleghenian orogeny led to the formation of the Pangaea supercontinent during the Permian Period (299 million to 251 million years ago). Geophysical seismic studies show that the southern Appalachian Mountains comprising the Ridge and Valley region, the Blue Ridge Mountains, and the Piedmont region belong to a crustal slab some 6–15 km (3.7 to 9.3 miles) thick that has been thrust 260 km (162 miles) westwards over the former continental margin.

14. Which of the following is not a way in which humans improve biodiversity?
O Introduction of invasive species
O Removal of pollutants
O Reducing fertilizer loads
Restoration of local communities
O Building artificial reefs
Answers
The introduction of invasive species is not a way to improve biodiversity.
• An organism, which causes economic or ecological harm in a new environment where it is not native is known as an invasive species.
• It can harm the natural resources in an ecosystem and at the same time can hamper human use of these resources.
• An invasive species can be a kind of plant, amphibian, insect, fungus, fish, bacteria, etc. and is not native to an ecosystem and results in harm.
• They possess the tendency to cause extinctions of native animals and plants, decline biodiversity, by competing with local species for limited resources, and changing habitats.
Thus, introducing invasive species is not a way by which humans can improve biodiversity.

b) Skeletal developments leading to the amphibian movement onto land probably evolved from lobe-finned fishes.
c) Fish fins are ancestral (homologous) structures to the flippers (forelimbs) of turtles.
d) The anterior gill arch formed the basis for the evolution of the vertebrate jaw.
e) The swim bladder ultimately led to the evolution of the amphibian urinary bladder.
Answers
Answer:
a) Teeth arose from the rough scales of ancestral sharks.
b) Skeletal developments leading to the amphibian movement onto land probably evolved from lobe-finned fishes.
d) The anterior gill arch formed the basis for the evolution of the vertebrate jaw.
Explanation:
The animals we know today have physical characteristics that are evolutionary adaptations of characteristics of their ancestors, which have undergone a series of evolutions and modifications over the years giving rise to new species that have resulted in the species we know today. This process of evolutions and adaptations also happened with the ancestral species of fish, which allowed that today, they had characteristics such as teeth and jaws. Many of these evolutions occurred even in different species, such as the evolution that allowed the amphibians to have a skeleton, which evolved from the spine fins of fish.
