Answer:
What did researchers learn from terra preta?... Because terra preta is loaded with so-called bio-char -- similar to charcoal -- it also can pull substantial amounts of carbon out of the increasing levels of carbon dioxide in the Earth's atmosphere, helping to prevent global warming.
How is bio-char different from the traditional Amazonian method of creating terra preta? Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, broken pottery, compost and manure to the low fertility Amazonian soil. ... Terra preta soils were created by farming communities between 450 BCE and 950 CE..
The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.
Terra preta is a type of dark, fertile soil found in the Amazon rainforest that is believed to have been created by indigenous people thousands of years ago. Researchers have learned from terra preta that it contains a high level of carbon, along with nutrients such as nitrogen, phosphorus, and potassium.
What is terra preta soil?Terra preta, or "black earth," is a type of dark, fertile soil found in the Amazon rainforest that is believed to have been created by indigenous people thousands of years ago. Scientists have studied terra preta to understand its unique properties and how it was created. Terra preta is a type of anthropogenic soil, which means that it was created by human activity rather than natural processes. It is believed that the indigenous people of the Amazon region created terra preta by adding biochar to soil along with other organic materials such as bones, shells, and manure.
Hence, researchers have learned from terra preta that it contains a high level of carbon along with nutrients such as nitrogen, phosphorus, and potassium.

Where were the metal cylinders located when they had the MOST
gravitational potential energy?
Just above the short plastic tube
O Just above the long plastic tube
O At the bottom of the long plastic tube
O At the bottom of the short plastic tube
Answer:
The answer is third example
At the bottom of the short plastic tube metal cylinders located when they had the Most gravitational potential energy.
What is Gravitational potential energy?The energy that an object has due to its location in a gravitational field is known as gravitational potential energy.
When an object is close to the surface of the Earth, when the gravitational acceleration can be assumed to remain constant at roughly 9.8 m/s2, gravitational potential energy is most frequently used.
The potential energy at a height h above that point is equal to the effort that would be needed to raise the object to that height with no net change in kinetic energy because the zero of gravitational potential energy can be chosen at any location.
Therefore, At the bottom of the short plastic tube metal cylinders located when they had the Most gravitational potential energy.

Which statements correctly describe herbivores and carnivores?
Choose all that apply:
Carnivores are often secondary or higher consumers.
Carnivores are often primary consumers.
Herbivores are often primary consumers.
Herbivores are often producers.
Answer:
The First and Third one for sure
Explanation:
Carnivores eat primary consumers as well as other carnivores if I'm not wrong, which would make them secondary or higher consumers.
Also, herbivores eat producers, which are plants and stuff and basically organisms that make their own food, which would make them primary consumers.
Amagnetwith alength of 10cmwasgiven to Meera and shewas told to break themagnetinto3 pieces.Before breaking the magnet had 1 north and 1 south pole. How many north and south poles will the magnets now havetotally in all the 3 broken pieces?
Answer:
3 North poles and 3 South poles
Explanation:
A magnet is a piece of object that produces a magnetic field outside itself. A magnet has a north pole and a south pole. Similar poles repel each other, while opposite poles attract each other.
If a magnet of 10cm is broken into 3 pieces, we will have 3 pieces of magnet. Breaking a magnet does not destroy the properties of the magnet. Rather, each piece becomes a full magnet with both north and south poles.
Breaking a 10cm magnet will give us 3 magnets with 3 north and 3 south poles with equal pole strength.

Explain how the structure (order) of DNA can determine the structure of a protein. Use as many of the following terms as you can in your explanation: DNA, base pairs, mRNA, tRNA, ribosome, amino acid, protein, codon, anticodon
The stages of DNA bases in a molecule can determine the order of amino acids in protein molecules. Groups of three bases called triplets represent different amino acids. This is the basis of the genetic code . A sequence of bases (genetic information) on DNA that codes for a protein is called a gene
Protein synthesis is the generation of proteins by cells that employ DNA, RNA, and different enzymes.
What is protein synthesis?It generally includes transcription, translation, and post-translational events, such as protein folding, modifications, and proteolysis the process of protein synthesis.
the mRNA contains the sequence of nucleotides transcribed from the DNA that defines the sequence of amino acids that a synthesized protein will have.
In mRNA, codons are triplets of nitrogenous nucleotides that code for amino acids and using ribosomes mark the beginning and end of protein synthesis.
Therefore, in contrast to mRNA codons, anticodons are triplets of nucleotides found in transfer RNA (tRNA). The linking of amino acids to the polypeptide chain being produced is carried out by tRNA.

Concerns about soil management are not the same in all climates. Suppose you own a farm in the state of Washington, where there is a lot of rain throughout the year. Which two issues would be of major concern in managing the soil on your farm?
Answer:
Soil Erosion
With so much rain coming all year, soil erosion will definitely be a problem if not handled. The splashing of the water on the soil and the subsequent runoff will increase soil erosion. Your farm will lose soil if this is not stemmed and losing soil can lead to a number of negative consequences.
Loss of Nutrients.
One such effect of soil erosion which will be another major concern is the loss of nutrients. This happens when the structure of the soil is broken down by the erosion and the various nutrients in the soil will be carried off as the rain moves away and lost to your farm.

what is the molar mass of Br2 in grams
Answer:
159.808 g/mol
Explanation:
Br itself is 79.904 g/mol. So multiply it by two.
The molar mass of [tex]Br_{2}[/tex] is approximately 159.808 grams per mole.
When calculating the molar mass of [tex]Br_{2}[/tex], also known as diatomic bromine, the atomic masses of the two bromine atoms (Br) found in the molecule are added together.
Bromine (Br) has a mass of roughly 79.904 grammes per mole according to its atomic weight.
Because of this, the molar mass of [tex]Br_{2}[/tex] is calculated as follows: 2 times 79.904 g/mol = 159.808 g/mol
As a result, the amount of grammes that constitute one mole of [tex]Br_{2}[/tex] is roughly 159.808.
