Answer:
The answer to this is simple.
There is a school of thought that believes that natural fires are necessary.
Explanation
They are required to reduce the density of the forests that are so thick that when they eventually burn, the effects are usually catastrophic. According to one source, some of these forests are over a hundred years old. When eventually these kinds of forests catch fire, they become very hard to manage and the destruction the leave are usually worse off than if they had not been allowed to so heavy and impenetrable.
Another reason put forward by this school of thought is that the countries who own these forests have politicised wildfires using them as an excuse to attract international funding/assistance because the fires are depleting the worlds protective greenery/earth biggest natural oxygen factory.

> So, to fill this shell, will it be easier for sodium to steal
seven more electrons from another atom, or will it be easier
for sodium to give up that one electron and get rid of that third
shell? Sodium is simply going to give away that last electron.
This means that it will lose an electron (negative charge) but
will keep the same number of protons (positive charges).
What will the sodium ion's overall charge be now?
40
- Exploring Anatomy & Physiology in the Laboratory
Answer:
+1
Explanation:
Sodium has one electron in its outermost shell. Sodium can not be able to accept seven electrons because the energy required for that process is very high. Sodium would rather loose its only valence electron to form a univalent positive ion Na^+.
This is an easier process. When sodium looses one electron, it now has a charge of +1.

Which of the answer choices provides an accurate example of how knowledge of nuclear reactions has been used to benefit society
select all that apply.
1.Radiation in correct doses may be able to prevent and treat illnesses caused by viruses, such as HIV and influenza.
2. Nuclear fusion can be easily activated and controlled in nuclear power plants and harnessed to generate clean electricity.
3. Controlled fission chain reactions can be used to produce electricity in a nuclear-powered submarine.
4.Medical imaging devices use radioactive elements with short half-lives to see through the human body and diagnose patients.
Answer:
Controlled fission chain reactions can be used to produce electricity in a nuclear-powered submarine.
4.Medical imaging devices use radioactive elements with short half-lives to see through the human body and diagnose patients
Explanation:
A submarine uses nuclear vision as a source of energy. The heat from controlled nuclear fission reactions produces steam which drives a steam turbine to power the submarine.
In the area of medicine, medical imaging is becoming a popular technique for diagnosis of many illnesses. These radioactive elements with short half lives are used to see through the human body for the purpose of diagnosis.

The individual components of a solution
Answer:
"can be separated using physical means" is the answer
A student describes the motion of particles in each of the four different states of matter
State 1: particles that are charged move freely
State 2: particles move freely at high speed
State 3: particles are locked in place
State 4: particles slide past one another
which state describes solids?
State 3: particles are locked in place describes the solid state exactly.
What is Solid State ?The physical characteristics of matter in which molecules or atoms are unable to move freely and are instead required to maintain their borders independently and in fixed connection to one another.
One of the four basic states of matter is solid.
The least energy molecules are those that form solids and are tightly grouped.
The solid's defining structural rigidity and resistance to external pressure.
Solids have precise mass, volume, and shape as well as compact arrangements of their constituent particles. Between molecules, there is not much intermolecular space.
Therefore, State 3: particles are locked in place describes the solid state exactly.

You can compress a substances in the gas state, but not in the solid or liquid state. Use the particle theory to explain why？
Answer:
we can compress gas instead of liqued or solid because it contains a lot of space between its particles.
Explanation:
particles of gases are far apart from each other and there motion are irregular as well, due to the free free space gases can be expressed.

How did Louis Pasteur’s experiments lead to new scientific understandings of germs? A.Experiments with cooking food showed that disease-carrying germs in food could be killed when heated. B.Experiments with different magnification lenses showed that germs were real and could be observed. C.Experiments with animals showed that dominant genes could lead to risks of disease. D.Experiments with shallow dishes showed that groups of germs could be grown so they could be seen without microscopes.
Answer:
A.Experiments with cooking food showed that disease-carrying germs in food could be killed when heated.
Explanation:
Louis Pasteur (1822-1895) is regarded as the father of immunology. He extensively studied microbes and their effect on food. He discovered that microorganisms were responsible for the spoilage of food.
His most important discovery was the fact that heating wine to 55°C will lead to the death of microorganisms and prevented wine from spoiling and did not affect its taste. This process is known as pasteurization.
Answer:
A
Explanation:
explain how heat is exchanged through potential and kinetic energy
Answer:
Kinetic And Potential Energy Working Together All forms of kinetic energy are the result of a previous state of potential energy. For example, the stored chemical potential energy of a battery converts to electrical kinetic energy to transport electricity to a light bulb, which radiates thermal kinetic energy.

Paper clips are made of stainless steel. Steel is a mixture. There are different kinds of steel that have slightly different ratios of substances. Stainless steel is made of iron mixed with high-density metals. Carbon steel is made of iron mixed with carbon, an element with a lower density than metals. Would you expect the density of stainless steel and carbon steel to be the same? Why or why not? Font Sizes
No, firstly bc stainless steel and carbon steel mixed with different things, high-density metals and carbon.
High-density metals and carbon both has different density which will affect the steel when they combined with iron. So it cant be the same.
