Formation of a gas, formation of a precipitate and formation of a slightly ionized product are the cases for the completion of ionic reactions.
What are the three conditions under which ionic reactions completed?The three conditions under which ionic reactions can run to completion i.e. formation of a gas, formation of a precipitate and formation of a slightly ionized product.
K+(aq) + Br−(aq) + Ag+(aq) + C2H3O2−(aq) → K+(aq) + C2H3O2−(aq) + AgBr(s)
Mg2+(aq) + SO42−(aq) + Ba2+(aq) + 2NO3−(aq) → Mg2+(aq) + 2NO3−(aq) + BaSO4(s)
So we can conclude that formation of a gas, formation of a precipitate and formation of a slightly ionized product are the cases for the completion of ionic reactions.

Is a law a theory or is a theory a proposed law
Answer:
Theory is a proposed law.
Explanation:
A proposed law is a law that has not yet been approved; a speculation made by an individual that has not yet been proven as a real thing. For example, I say that ice cream is now free for all, and that would be a completely proposed law since no one has approved that but me.
Answer:
Neither
Explanation:
A law is something in science that can be proved through experimenting. A law does not attempt to explain why something is the way it is, it only states it.A theory is an idea that has a large amount of scientific data backing it and is the accepted answer by most scientists, but there is no way to experiment on a scientific theory. A theory will never be able to become a law. A theory explains what it is describing.An example of a law is the law of conservation of energy, which has to do with how energy is used. Scientific experiments can be done to observe energy.
An example of a scientific theory is the theory of natural selection. Based off of data and observation, the theory of natural selection has been formulated, and the theory of natural selection explains why.

impulse begin in a
neuron?
A. A positive charge is created in the cell that travels
down it.
B. The cell filling with sugars gives it an energy surge.
C. Water moves down the cell by osmosis.
D. The cell contracts like a muscle and connects to the

A positive charge is created in the cell that travels down it does a nerve
impulse begin in a neuron. Thus, the correct option is A.
How the neuron get stimulus?When a neuron receives a chemical stimulation, a nerve impulse is formed. The electrical action potential of the nerve impulse passes along the axon membrane to the axon terminal. Neurotransmitters are released at the axon terminal, which transfer the nerve impulse to the next cell.
The resting potential of a neuron is the electrical differential across its membrane. The sodium-potassium pump, a transport protein, creates the resting potential. This protein generates a positive charge by moving a high number of sodium ions (Na+) outside the cell.

What are the consequences of the depletion of natural resources?The consequences of this ecological excess are increasingly evident, with imbalances such as the extinction of species, scarcity of fresh water, soil erosion, loss of biodiversity and global warming.
Reaching this limit means that all the resources used for the survival of humanity are depletion and we are in “debt” to the planet, in this case it is the graphic representation of this depletion.

Answer:
A) Red Light
B) Green Light
A) Blue Light
B) Cyan Light
Explanation:
I believe that you are overthinking this. White light is a combination of all the colors on the visible spectrum. This means that if you shine a white light through a red filter, it will only show the red light that is in the white light. There will be only red because the other colors of the spectrum are not visible due to the filter.
This rule applies to all of the filters.
From 2007 to 2010, the mink population stayed fairly consistent, but in 2010, the population dramatically decreased. Which of the following could describe what happened to the population of minks?
The mink population ran out of space to live so many died
A catastrophic event occurred like a disease or big natural disaster that quickly wiped out a large number of mink.
There were more voles for the mink to eat, so their population increased
The bears began to eat the mink in 2010 so the population of minks decreased.
The most likely event that led to a sudden decrease in the population of mink in 2010 would be a catastrophic event. The correct option would be B.
Decrease in populationA sudden and sharp decrease in the population of an organism can be caused by a host of factors. These include:
catastrophic events such as disease outbreaks, natural disasters, famine, etc. a sudden appearance of predators in the environmentIf the predator has always been in the environment with the population of the organism, this will not result in a sharp decline in the population. A population of predators suddenly joining the environment may be the only cause for a sharp decline in the population of the organism.

Describe what happens when blood glucose levels are not kept stable.
Blood glucose levels should be kept stable in the body because :-
A rise in glucose level can cause diabetes mellitus or simply diabetes due to too much glucose in the blood stream.In this patients pass urine too much loaded with sugar. Also he feels thirsty due to too much loss of water and becomes weaker and weaker.A fall in glucose level can cause hypoglycemia.
Even a little fall of glucose level in the bloodstream can bring a patient in a state of coma. The person gets frequent headaches, vomiting, dizziness, etc.The regualtion of glucose in the body is done by two main hormones secreted by an endocrine gland called pancreas.
These two hormones are - Insulin and Glucagon.Insulin lowers the glucose level in the body whereas, Glucagon helps in increasing it.Therefore, the glucose level should be always kept stable in the body.
