Answer:
During the water cycle, the water on the earth's surface gets evaporated leaving the impurities behind and enters into the atmosphere as water vapor. Thus, the water cycle removes pollutants from earth’s water.
Explanation:
Water cycle is the continuous movement of water on the earth's surface and the atmosphere. Some of the water from the oceans, lakes, rivers etc gets evaporated by sunlight and enters into the atmosphere as water vapor. Also from the processes like sublimation (ice and snow) and evapotranspiration (plants), water vapor reaches the atmosphere. This vapor is then condensed into clouds and later falls back from the sky on to the earth's surface as precipitations like rain, snow etc. During the evaporation, the pollutants (impurities) in the water sources are left behind. Thus, the water cycle removes pollutants from earth’s water.
B) Vacuoles allow water to enter and exit the paramecium.
Nails are made of iron because, iron is strong and sturdy; although nail rust when it undergoes oxidation when expose to water but it is not explosive.
Barium and phosphorus are not suitable for nail making because of their properties.
Barium is an element which reacts with virtually all non metals, forming poisonous products which are dangerous to health and to the environment. It also reacts explosively with water.
Phosphorus is not found in its pure form in nature, it conducts electricity and it is combustible in nature.<span />
The fluid inside of the Extracellular Matrix is Extracellular Fluid. Extracellular Fluid is also called ECF. ECF is mostly tissue fluid. It is also made up of a large amount of intravascular fluid. The remaining smaller amount of ECF is transcellular fluid.
hope i could help :)
The observation from the first question would tend to disprove the idea that evolution is based on b. inheritance of acquired characteristics because according to the experiment <span>theory of <span>adaptation was taken as a basis.
The answer for the next question is definitely adaptation as at first every live -being should get used to its environment in order to develop and so on.</span></span>
