B. Biosphere
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.
The given statement is true.
Explanation:
Research work needs to be conducted in some particular, well-organized processes. This systematic process aims at gathering ample of information to reach a conclusion by the researcher.
It includes-
(i) identification of a problem to raise a question on that;
(ii) reviewing that problem and learning all about it;
(iii) clarification of the problem is needed which make the scope of study narrow;
(iv) defining the concepts and terms of the research;
(v) studying a particular group which is the objective of the research; (v) The methods and participation is reviewed;
(vi) Collection of data is needed;
(vii) analyzing the data is the last step.
I have to say airborne infections. If the infection is airborne it can travel and infect many people more quickly and wide spread.
