Final answer:
Genomes of an oak tree and a grizzly bear differ in numerous aspects, even though they may code for similar adaptations.
Step-by-step explanation:
The genomes of an oak tree and a grizzly bear are similar in that they share the same number of genes, which means they both have a similar number of functional units of heredity. However, their DNA is not made of the same components as they have different base pairs. Additionally, their DNA sequencing is not identical, meaning that the arrangement of nucleotides in their genomes is different. Therefore, option D, they code for similar adaptations, would be the most accurate choice as oak trees and grizzly bears may exhibit similar genetically determined characteristics or adaptations that help them survive in their respective environments.
