Answer;
D. Rift valley
Explanation;
-A divergent boundary also called the divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Most divergent plate boundaries are underwater (Iceland is an exception) and form submarine mountain ranges called oceanic spreading ridges.
-Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys.They are constructive boundaries. Convergent boundaries on the other hand are areas where plates move toward each other and collide.
Plasticity is most adaptive when the environment change <u>Slowly and predictably </u>throughout an organism's life.
The ability of individual genotypes to create various phenotypes when exposed to various environmental situations is known as phenotypic plasticity. Here, the emphasis is on the role of plasticity in evolution rather than the evolution of plasticity itself, i.e., the evolution of phenotypic traits and organismal variety through plasticity. Phenotypic plasticity is a crucial characteristic of developmental systems that enables the organism to deal with environmental variability and/or unpredictability, although its significance for adaptive evolution is still debated.
