Some populations have cooperative relationships. This is where members of the same species work together for survival, therefore the correct answer is option C.
What are biomes?Biomes can be defined as regions specified by particular biological and geographical communities that evolved because of the shared regional climate of that region.
In the natural world, symbiotic partnerships can take one of three main forms: parasitism, commensalism, or mutualism. Mutual benefit: both parties win.
There are certain populations that work together. The right response is option C since this is a situation in which individuals of the same species collaborate in order to survive.

What is the correct term for the flow of charged particles?
A. electricity
B. electric force
C. electric force
D. electric chargeelectric charge
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.

why do you suppose the stomach contains acid? what do you think happens when there is more acid than food in the stomach?
PLZ help I need an answer ASAP
50 points to the first person!!!!!
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.
