Answer:
Water
Explanation:
When a colloid such as a gelatin forms, water is entrapped by the process of protein coagulation. 
Colloids can be describes as particles of solid having spherical diameter between 1 and 100 nm which are dispersed in the liquid medium. Coagulation can be described as a process in which particles aggregate and lead to the formation of flocs. Flocs can either settle in water or can easily be seperated from water. 
 
        
             
        
        
        
The evolutionary tree is not observed here but it is possible to answer this question by observing which nucleotide is found in the root of the node. It indicates the first substitution.
<h3>What is an evolutionary tree?</h3>
A phylogenetic evolutionary tree is a diagram used to show the evolution of a given taxonomic group (for example, a group of species).
It is possible to trace the evolution of a given taxon by tracing the nucleotide substitution observed from a common ancestor.
In an evolutionary tree, the root of the node is represented by the common ancestor and therefore the presence of a particular nucleotide (either T or C) in that position can be considered as the ancestral character.
