At which position will the bar magnets most likely experience the least magnetic potential energy between them?
A diagram is shown of 4 different positions for a pair of magnets.A table shows 4 arrangements of a pair of magnets. In the first row, position 1, shows two horizontally oriented magnets as rectangles with the left end in red labeled N and the right end in blue labeled S. A large gap exists between the magnets. The second row, position 2, shows the magnets slightly closer together. In the third row, position 3, they are even closer. In the fourth row, position 4, the magnets are connected, with the blue end of the left magnet connected to the red left side of the magnet to the right.

Why is cellular respiration essential for homeostasis? (4 points)
To create energy that the cell can use
To make air in the body
To remove oxygen from tissues
To make new types of cells
Answers
2. The only form of energy a cell can use is a molecule called adenosine triphosphate (ATP). Chemical energy is stored in the bonds that hold the molecule together. ADP can be recycled into ATP when more energy becomes available
3. The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
4. The regulation of tissue oxygenation is based at the start from the ability of the respiratory system to fully oxygenate the arterial blood which the heart then delivers to the peripheral tissues. The need for different levels of respiration varies with the physiologic state of the organism (e.g., sleep, excitement, exercise). The respiratory system must try to maintain constant levels of O2, CO2 and H+ in the arterial blood which then ensures relatively constant levels of these important substances in the interstitial fluid. For O2, one needs an adequate supply to meet cellular metabolic requirements. For CO2 and H+, one needs to maintain the acid–base status of the body's cells
5. New cells are created from a process called cell division. The new cells are produced when a cell, called the mother cell, divides into new cells called daughter cells. When two daughter cells have the same number of chromosomes as the original cell, the process is called mitosis

What is the correct term for the flow of charged particles?
A. electricity
B. electric force
C. electric force
D. electric chargeelectric charge
Answers
Answer:
I would say electric current, but since that isnt a given choice, i would choose electricity.
Explanation:
an electric force is an attraction between two charged particles, not the flow.
electric charge is the cause of the electric force.
again im not sure, hope this helps!
The correct term for the flow of charged particles is known as electric current or electricity. Hence, option A is correct.
What is Electrical energy?Charged material experiences a force when exposed to an electromagnetic field because of the fundamental characteristic of electric charge. It's conceivable for electrical ions to be positive or negative. Two charges that are opposed to one another repel one another.
An object with no net charge is said to be "neutral." Classical electrodynamics refers to the older theory of how charged particles interact, and it is still valid for problems that do not necessitate accounting for quantum phenomena.
The net charge of an isolated system, which is the total of the negative and positive charges, cannot change since electrical current is a conserved property. Electric charge is carried by subatomic particles.
Therefore, it concludes that flow of charged particles is termed as electricity.

Answer:
Your stomach acid helps you break down and digest your food. Sometimes, a higher than normal amount of stomach acid can be produced. This can lead to symptoms like abdominal pain, nausea, bloating, and heartburn.
Explanation:
brainliest plz
Answer:Stomach acid, or gastric acid, is a watery, colorless fluid that’s produced by your stomach’s lining.It’s highly acidic and helps break down food for easier digestion. This helps your body absorb nutrients more easily as food moves through your digestive tract.In order to break down everything from meat to tough, fibrous plants, stomach acid has to be highly acidic.Your body is designed to handle normal levels of stomach acid so it doesn’t cause you any illness or health complications.
Explanation:Stomach acid encounters a lot of things on behalf of your body. It breaks down the foods you eat into easier-to-digest particles. It also acts as the first line of defense against pathogens and microbes that could make you sick.
