The carbon that plants need for photosynthesis comes from (carbon dioxide gas in the atmosphere)
Plasma is important because
-it helps transport red blood cells facilitating transport of oxygen
-regulates body temperature
-it for forms a medium in which substance dissolve

In the period when the lush ancient forests exited on Earth, the ones that provided the material for the formation of the coal that we use nowadays, Australia did not provide the right conditions for the existence of these forests.
The problem was that Australia was located very close to the South Pole in that period. Because of its location, Australia was colder and drier than most of the landmass on the Earth. By having less precipitation, and colder climate, Australia was not suitable for the tropical rainforests of that period, thus it did not had the material from which the coal formed latter on in the geological time scale.
The answer is : b. Theoretically, noise pollution could be so great that it could kill a person. Noise pollution affect our sense of hearing... leading to hearing loss. It also disturb our sleep which could lead to fatigue. Long-term noise above a certain level can have a harmful influence on our health. Research shows that road traffic and aircraft noise increase the risk of high blood pressure. Noise pollution also affects wildlife, where animals depend wholly on their hearing for hunting.
Answer:
Fault
Explanation:
A break or crack in earth's lithosphere along with rocks move. Earth is made up of 4 basic layers a crust,mantle,outer core,inner core and lithosphere. A solid crust and hard layers of mantle make up a region name the lithosphere. The lithosphere is made up of pieces of tectonic plates. These plates are constantly changing and move towards the mantle. Non-stop movement of tectonic plates causes stress on the earth's outermost layer i.e,the crust. When these stresses extends it leads to cause cracks called faults.
