Explanation:
describe what is happening to rock climbers’ body systems and cells at the small scale.
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.

The student mixed up 500ml of salt solution. He weight it and found it mass to be 585g. will his shake up toy work the way that he want it to work?why or why not?
Remember, 1 mL = 1cm
Show your math
Answer:
...
Explanation:
find density of salt solution 585g/500cc = 1.17g/cc
leaves density = 1.25g/cc, stars density = 1.12g/cc
Stars float, leaves sink. since everything is in g/cc, you do not have to worry about the info 1ml=1cc.
density = mass / volume.
density of salt solution = 585g(mass)/500cc(volume)
The picture shows a spoonful of salt being added to a glass of water. What physical property of the salt is being demonstrated?A.
A.
solubility
B.
density
C.
boiling point
D.

Order the list of Earth’s water resources from greatest to least: Rivers; Ocean water (salt); Ice Caps/glaciers; Groundwater
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?
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.

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.

Which property of physical changes explains why matter is conserved in a physical change? The arrangements of particles do not change, and the bonds between atoms do not break.
Mass, not energy changes in a physical change.
Energy and mass change in a physical change.
The bonds between atoms do not break, it's only the arrangement that changes.
Mass is the amount of matter in an object, and weight is the downward pull on an object due to gravity. Which property of physical changes explains why matter is conserved in a physical change? The bonds between atoms do not break; it is only the arrangement that changes.

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.
