Explanation:
Incinerators are not helpful in reducing pollution as they produce a lot of ash and smoke so it increases the air pollution by burning of waste. 
Solar and wind energy are the clean source of energies replacing the fuels. Catalytic converters reduce the air pollution from the exhaust fumes of vehicles.

Answer:
The researcher centred on the potential uses of biochar, charcoal primarily used for agricultural and to improve the quality of post mining sites.
A method called mountaintop removal was used by mining firms. This means that they remove rock and mineral deposits off the top of the mountain to gain access to within the coal seams. The resulting soil is infertile and strongly acidic.
The compacted soil after mine proves harder to  bring seed into the soil. 
The researchers  try to use biochar to help reforest the soil at the post-mining site. Before it was reseeded and replanted, they got permission to add a layer of biochar to a post-mining site. the team created 
“planting cells” of biochar‐enhanced soil on the post‐mining site and that showed improvment in the sapling growth.
 
        
             
        
        
        
Answer:
Bacteria
Explanation:
Bacteria constitutes large group of unicellular organisms that lacks membrane bound organelles and constitute cell wall. Bacteria are used for the production of recombinant proteins.
Bacteria can be selected easily for the recombinant protein formation. The plasmid of bacteria is helpful for the integration of desired genes and the production of protein. The bacteria culture can be maintained easily in the laboratory. The different strains of bacteria with different traits can be used for the production of different recombinant proteins at low cost. 
Thus, the correct answer is option (1).

Answer:Yes
Explanation:
Binary fission is a type of asexual reproduction where a parent cell divides, resulting in two identical cells.
