What is unique about obtaining water from an artesian well?
The water is heated by magma or hot rocks.
The water is found in an impermeable layer.
The water is under pressure naturally and no pump is needed.
A mechanical pump must be installed to bring water to the surface.
Answer:
The water is under pressure naturally and no pump is needed.
Explanation:
C
The water in artesian wells is under natural pressure and requires no pump.
What are artesian wells?They are wells that contain water that is under natural flowing pressure. Thus, there is no need of using artificial pumps in order to get the water to the surface.
Artesian wells are dug on lands with special geological features that enable the water to flow out under natural pressure.
Artesian wells differ from other types of wells that require mechanical or electric pumps before the water can get to the surface.

How does melanin provide protection against skin cancer? use absorb
energy
light in your sentece
The melanin provides protection against skin cancer by absorbing harmful UV light from the electromagnetic spectrum.
What is electromagnetic spectrum?
The electromagnetic spectrum consists of radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

How does this evidence help explain why the skin cancer rate is higher in Australia than in Brazil, even though the two countries get the same amount of sunlight?
Answer:
The Ozone layer
Explanation:
Ozone in the atmosphere can absorb ultraviolet light, which stops the light from reaching Earth’s surface, so people absorb less of it. Australia has less ozone than other places, like Brazil, and this is why Australia gets more ultraviolet light.

CH4 + __O2 → CO2 + ___H2O
balance this equation
Explanation:
need points bye have good day
Answer:
CH4+2O2→CO2+2H2O
Explanation:
Start with the least common atoms and leave things like H and O to the end.
You need to have the same number of methane reactants as carbon dioxide products because there is one carbon in each. I’ll set them both to 1 for now. O see two things with oxygen on the product side so we will have to juggle numbers a bit to figure out those. There is only H in the water so we’ll go there next. One CH4 gives 2 water molecules so we have that done now. At last we can tackle the O atoms. In two waters there are 2 and in the CO2 there are two more so a total of 4 O atoms in the products so we need two O2 molecules in the reactant side.

In an exothermic reaction, chemical energy is converted to _____.
1.thermal
2. mechanical
The chemical reactions are generally of many types. The exothermic and endothermic reactions are important among them. In an exothermic reaction the chemical energy is converted to thermal energy. The correct option is 1.
What is exothermic reaction?The chemical reactions which proceed with the evolution of heat energy are defined as the exothermic reactions. The chemical reactions which proceed with the absorption of heat energy are called endothermic reactions.
In an exothermic reaction, system loses heat to surroundings. Since heat is given out in exothermic reactions, the enthalpy of the products will be less than that of the reactants.
In exothermic reaction, q will be negative and the enthalpy change will be also negative. In this reaction chemical bonds are broken and new bonds are formed. The chemical energy is converted to kinetic energy which is released as heat.
Thus exothermic reaction releases thermal energy.
