Answer:
Polyploidy is the state of a cell or organism having more than two paired (homologous) sets of chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two sets of chromosomes—one set inherited from each parent. Hence ploidy is defined with respect to a cell.

Answer:
C) predation
Explanation:
Such an insect would serve as a prey to a predator in a prey-predator relationship. Such relationship is a predation.
Predation is an act of feeding in a prey. The preys are weaker and smaller organisms which can easily be overpowered by the bigger predators. 
When an insect evolves to resemble a plant twig, it is an evolutionary mimicry. Such organism that evolves must be prey. This presents the prey an evolutionary advantage for it to be evaded by the devouring predator. Mimicry is an evasive tactics. 
In parasitism, one organism benefits while the other, the host, suffers from the relationship. Here, the parasite is lives inside the host. A mimicry won't apply here.
