False, because if it is air pollution, the polluted particles diffuse in the air and then travels. In addition, for noise pollution, sound waves travel!
        
             
        
        
        
Correct answer - 120 for Thymine.
Why? - 320 Nitrogen bases. 
Cytosine = 40, Cytosine = Guanine.
Therefore Guanine = 40. 
320 - 80(Cytosine and Guanine)
240. 
Adenine and Thymine = ? 
Adenine = x and Thymine = x.
2x = 240.
X = 240/2
X = 120.
Adenine 120, Thymine = 120, Cytosine = 40 and Guanine = 40.

Answer:
The correct answer is option d, that is, endocytosis. 
Explanation:
A procedure in which a component gains entry within the cell without getting passed through the cell membrane is termed as endocytosis. In this process, the cell captivates the substances from the external of the cell by engulfing and combining them with its plasma membrane.  
The process is further differentiated into three distinct kinds. These are phagocytosis, pinocytosis, and receptor-mediated endocytosis.
