Answer:
If the shape of an enzyme changes then the enzyme will no longer be able to perform its function.
Enzymes can be described as bio-catalysts which usually speed up a chemical reaction. Each enzyme has a particular substrate which fits into the active site of the enzyme. Every enzyme needs a particular temperature and pH for its functioning. If the shape of an enzyme changes, then it will no longer be able to perform its function and will become denatured.
quartz
vinegar
sugar
salt
As you indicate, quartz or silica is exceptionally stable because of its exceedingly low solubility. Thus, option A is correct.
The amount of an oil that will dissolve in the water column at a specific temperature and pressure is known as its solubility in water.
The compound's water solubility increases with increasing polarity. The high water solubility of BTEX chemicals is one reason why they are found in groundwater so frequently.
In pure water at neutral pH, room temperature, and pressure (a saturated silica solution under these conditions only contains 6 parts per million of silica dissolved in water).
Quartz is about water-insoluble at normal temperature. There is no need to be concerned about quartz crystals being harmed by frequent washing.
Therefore, quartz substance is insoluble in water.

Answer=C
B. Fossil fuel reserves will never be depleted.
C. Fossil fuels are easily renewed.
D. Fossil fuel use does not affect the environment.
Answer:
The correct answer is A. Fossil fuels are cheaper than alternative forms of energy
Explanation:
Fossil fuels are made from organic matter of dead animals and mainly plants who were buried in the soil over hundred and thousand of years. We use fossil fuels because they are the best source to provide energy in the current time.
Fossil fuels are easily available and are present in very large amount which is the main reason for it to be cheaper. Fossil fuels like coal, petroleum or natural gas are more cheaper and efficient than alternative forms of energy like solar or wind energy.
But in future these fossil fuel will not be there and alternative forms of energy will become the primary and cheaper source of fuel.
Answer: Option A
Explanation:
Fossil fuels are formed inside the earth when dead plant and animal remains have enormous pressure on them. They get converted into coal and other types of fossils fuels.
They are not that that costly and is used by people at different places as it is so economical.
These are cheaper than other other sources of fuels. These are available in huge amount inside the earth and can be used for a very longer period of time with a very cost.
