The answer is A. skeletal system
Answer:
Elastomeric
Explanation:
An elastomer is a polymer whose main characteristic is elasticity and can even recover its shape after being deformed
The chemical composition of an elastomer is the grouping of thousands of molecules called monomers, which join together forming huge chains. These large chains of polymers are those that give elasticity since they are flexible and are intertwined in a very messy way.
When an elastomer is stretched, its molecules align, allowing many times to take a crystalline appearance. However, upon releasing the tension, it immediately returns to its original state of elastic disorder. The above distinguishes elastomers from plastic polymers.
<h3>prey and its food source</h3>
The presence of a top predator also helps to maintain balance in an ecosystem by influencing the behaviour and movements of its prey through the fear of being caught.
<h3>What is Trophic Cascade ?</h3>
trophic cascade, an ecological phenomenon triggered by the addition or removal of top predators and involving reciprocal changes in the relative populations of predator and prey through a food chain
- When a top predator is removed from an ecosystem, a series knock-on effects are felt throughout all the levels in a food web, as each level is regulated by the one above it.
- The results of these trophic cascades can lead to an ecosystem being completely transformed.

The answer is; B
Mutation is one source of variation (in addition to sex and gene flow). Mutations are rare and occur in a small proportion of individuals. However, due to the advantage that the genetic mutation confers to these individuals, their chances of passing the genes to the next generation is higher than that of the general population.
This way, the allelic frequencies of these advantageous mutated genes increase with each generation and eventually become the majority population over time.
