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.

Brendan made a chart to categorize the characteristics of animals.
An empty 2-column table titled Characteristics of Animals. Column 1 is labeled Always. Column 2 is labeled Sometimes.
Which phrase should be written in the column titled "Sometimes”?
Are multicellular
Have membrane-bound organelles
Produce their own food
Display an asymmetrical body plan
Answer:
Im gonna say produce their own food, i may or may not be wrong. sorry
Explanation:
Animals are multicellular and have membrane-bound organelles, sometimes display an asymmetrical body plan and sometimes they produce their own food. Thus, the correct option are C and D.
What is an asymmetrical body plan?Animals are the organisms which are multicellular eukaryotic organisms. Animals have all membrane-bound organelles such as mitochondria, chloroplast, etc.
Animals sometimes produce their own food. Animals also are asymmetrical sometimes because they have disproportionate arrangement of body parts, which exhibits no pattern. However, animals are also symmetrical sometimes because of the proportional arrangement of body parts and pattern.
Therefore, the correct option are C and D.

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.

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.

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.

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.
