describe what is happening to rock climbers’ body systems and cells at the small scale.
Answers
Answer:
It is being pressured!
Explanation:
The pressure point changes so people aren't used to that certain pressure
As a rock climber climbs higher, the systems and cells experience a decrease in pressure.
Pressure decreases with height. Hence, the higher you go, the lesser the pressure becomes and this may have obvious implications on the cells and systems of a rock climber.
As air pressure decreases at higher altitude, a rock climber may find it difficult to breathe because of the sudden decrease in air pressure hence the respiratory system is affected.
Prolonged exposure to high altitudes may lead to a decrease in the amount of oxygen in blood causing the heart to pump harder.

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?
Answers
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.

A. 2Mg + AlCl3 → Al + 2MgCl2
B. 3Mg + 2AlCl3 → 2Al + 3MgCl2
C. Mg + 2AlCl3 → 2Al + MgCl2
D. 3Mg + 4AlCl3 → 4Al + 3MgCl2
Answers
Explanation:
Reactants side Products side
Mg - 3 Mg - 3
Al - 2. Al - 2
Cl - 6 Cl - 6
The chemical equation which is balanced according to law of conservation of mass is 3 Mg + 2 AlCl₃ → 2 Al + 3 MgCl₂.
What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

What role does gravity play in the water cycle?
Describe the flow of one molecule of water through the water cycle, beginning in the ocean.
Answers
Answer:
A and E.
Explanation:
When water evaporates, it leaves the salt. When rain falls, the salt is diluted. The sun causes the evaporation. The also the sunlight is the energy source, the greatest force propelling the water cycle is gravity. Gravity is the force of attraction between two objects, and Earth’s gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Also Water travels in a continuous path through Earth called the water cycle. The journey starts in the Earth's oceans. As the Sun heats the ocean, the water evaporates into a gas. The gas meets cooler air, and the gas changes into droplets of tiny water molecules. This process is called condensation. Little droplets of water fall back down to Earth again as precipitation. The precipitation fills up the rivers and various other things and the cycle begins all over again. Now with this being said, there is much more than just this!

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.

CH4 + __O2 → CO2 + ___H2O
balance this equation
Answers
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.
Hope this is useful.
Drinking water has two sources. It can come from surface water, such as reservoirs or rivers. Or it can come from groundwater where it either naturally surfaces in a spring or where it must be pumped to the surface from a well. Where does your drinking water come from?
Answers
82% of drinking water supplies in Ireland are sourced from surface water (rivers and lakes) and 18% comes from groundwater - it depends where you live (quick g00gle search should answer you question)
Our drinking water comes from the underground sources like wells, hand pumps, etc.
What are the sources of water?Sources of water are the places from where the water comes to earth for the uses.
In our houses drinking water comes from the underground sources, through the wells, hand pumps, etc. From that source we get natural water for the drinking purposes.
Hence we get water from underground sources.
