Answer:
The correct answer is - destroying their leaves.
Explanation:
Gypsy moths are the most important moth species as their caterpillar defoliate the leaves of the trees, shrubs, and other plants and ultimately kills them.
These moths destroy most of the leaves or separate the leaves from the trees. These moths lay their egg on the leaves of the trees and plants and their caterpillar eat these leaves for food and nutrition.
 
        
             
        
        
        
A pH environment has a significant effect on an enzymes. It can affect the intramolecular forces and change the enzyme's shape -- potentially to the point where it is rendered ineffective. With these effects in mind, typical enzymes have a pH range in which they perform optimally. For example, alpha amylase, which found in the mouth, operates most effectively near a neutral pH. However, lipases operate better at more basic pH levels.
        
             
        
        
        
Answer:
Option C, cladistics reveals relative evolutionary branching by utilizing genetic analysis
Explanation:
Cladistics classification is a way of classifying organisms biologically in a way that a relationship between their shared traits could be established which leads to identification of closely related organism and species. It further helps to identify ancestry history of closely related species to identify closely related common ancestors and the evolution of various characteristics.
Basically in  Cladistics  study, species are arranged on a phylogenetic tree based on the time of their emergence from any other group. 
Hence, option C is correct.
