 The best option for showing locations of housing and industry on a city map is drawing a circle around the industrial areas. Thus option "C" is correct.
<h3>What are general reference maps?</h3>
Road maps and historical maps are general reference maps as it shows the physical (natural and man-made) features in an area and can use different colours to differentiate different rods and locations.
Early formed maps or historical maps are general reference maps as it can represent the discovery of a landscape briefly.
Thus option "C" is correct.

Answer:
Explanation:
In the  structure of  Nucleic acids the nucleobases (nucleotide and bases) are arranged is  a specific  form.This form of arrangement is called Base stacking.It simply refers to the bond formed between the adjacent bases.
These nitrogenous bases of (A,T,C.G) pairing  in DNA are in planes in geometry.The bases planes stack  with one another.This form of arrangement  give rooms for more Van der Waals interactions in the plane of the bases.Although the Van der Waals are weak interactions,the bond ensure that these bases are braided or twisted together to give maximum energy,to maintain stability of the bases,and therefore of DNA structure 
Therefore in water  and other aqueous solution the stability of  structure of DNA is enhanced by the base stacking,(coiling or twisting)with maximum van der waals interaction  among the bases, than the hydrogen  bonds formed between bases.Generally there are more stacking among G-C,than A-T,thus the former pairing contribute more the structural stability than the latter (A-T)
 
        
             
        
        
        
Answer:
plankton
Explanation:
plankton are eaten by pretty much everything as they are so small. they also get food through photosynthesis therefore they do not eat any other animals. i am pretty certain krill eat them but i dont know
