It fertilizes soil
It contains carbon

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 are 5 examples that the muscles are working in pairs
Answer:
Muscles that work like this are called antagonistic pairs. In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens.
...
Antagonistic muscle pairs.
Biceps Triceps
Hamstrings Quadriceps
Gluteus maximus Hip flexors
Gastrocnemius Tibialis anterior
Pectoralis major Latissimus dorsi
Answer:
Muscles that work like this are called antagonistic pairs.In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist.For example, when you perform a bicep curl, the biceps will be the agonist as it contracts to produce the movement, while the triceps will be the antagonist as it relaxes to allow the movement to occur.The biceps contracts and raises the forearm as the triceps relaxesAntagonistic muscle pairs
The following groups of muscles are antagonistic pairs:Biceps
Triceps
Hamstrings
Quadriceps
Gluteus maximus
Hip flexors
Gastrocnemius
Tibialis anterior
Pectoralis major
Latissimus dorsi
To allow antagonistic pairs to work efficiently, other muscles called fixators assist by supporting and stabilising the joint and the rest of the body. Some fixators also assist the agonist and act as a synergist.The trapezius muscle can act as a fixator when the biceps is flexing the elbow joint.The abdominals can act as fixators to stabilise the body for hip and knee movements.

what is the essence of recognizing the different species of organism in our country 1 paragraph pls
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.

A scientist helps a colleague do a better experiment by:
O A. laughing when a common and avoidable mistake is repeated.
B. offering advice about how best to perform a standard procedure.
C. explaining why a hypothesis does not need to be tested in an
experiment.
D. refusing to allow anyone else to use an expensive instrument.
Answer:
B. Offering advice about how best to perform a standard procedure.
Explanation:
Helping others can be in different ways, be it helping out or by giving encouraging words or advice. But in all aspects of help, there is always a positive outcome if help is given in the right way and at the right time. And it is also how one person lifts another.
A scientist can help a colleague out by offering advice and telling the person how to best perform a standard procedure. This will help the colleague do better in the experiment and also help ensure that the right things are done and the efforts are successful. The other options are all negative in their 'approach' which will only hinder the colleague in his/her works.
Thus, the correct answer is option B.
Answer:Offering advice about how best to perform a standard procedure.
What is the process consumers use to release energy from food?
Answer:
Primary producers—plants, algae, and bacteria—make up the base of the pyramid, the first trophic level. Through a process called photosynthesis, producers capture energy from the sun and use it to create simple organic molecules, which they use for food. Consumers constitute the upper trophic levels.

What is photosynthesis?
Photosynthesis is the process whereby plants manufacture their own food with the use of sunlight and carbon dioxide.
When this occurs, (energy in form of glucose) and oxygen are produced. The oxygen is released for animals to use.
Thus, producers capture energy from the sun and use it to create simple organic molecules, which they use for food. Consumers constitute the upper trophic levels.

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.
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.
