Answer:
Capillary Action
Explanation:
Water molecules are attracted to the molecules in the wall of the glass container.Water molecules stick together because of polarity; a water molecule has a slightly positive end and a slightly negative end. Opposite charges attract, creating a cohesive force. Water molecules are attracted to each other. Which are basically the definitions of adhesion and cohesion.

Answer: C. Microevolution is small scale change to the gene pool of a population while macroevolution is larger scale changes that lead to speciation.
Explanation:
Microevolution can be defined as a small change in the gene frequency within a gene pool of the species, these changes will be inherited by the organisms and there will not be any drastic change at the species level. But in case of macroevolution the large scale change occurs at the genetic level, which retain for long. This leads to development of new organisms or results in speciation. 
 
        
             
        
        
        
The answer is false. To explain further, let G have vertices
{v1, v2, v3, v4}, with ends between each pair of vertices, and with the mass on
the edge from vi to vj equal to I + j. Then each tree has a bottle neck edge mass
of as a minimum of 5, so the tree containing of a track through vertices v3, v2,
v1,v4 is a least bottleneck tree. It is not a least spanning tree, though, subsequently
its total mass is greater than that of the tree with edges from v1 to every
single vertex.
 
        
             
        
        
        
Answer:
i think its the first one (I'm not sure tho but i will leave the explianation) 
Explanation:
 Organic molecules are usually composed of carbon atoms in rings or long chains, to which are attached to other atoms of such elements as hydrogen, oxygen, and nitrogen.
(hope its clear )
