Answer:
<em>The correct option is d) gymnosperms and angiosperms</em>
Explanation:
Gymnosperms can be described as plant species which do not produce flowers. These plant species produce cone and seeds instead of flowers.
Angiosperms can be described as the plants which produce flowers. These plant type comprises of eggs which when fertilized develop into seeds. Angiosperms are also known as flowering plants.
Environmental changes (such as a natural disaster) may cause adaptive responses in organisms, such as the Galapagos finches. Due to the islands getting hard-hit by natural disasters, the once-same species of finch were isolated in separate islands. Each generation, through natural selection, adapted to their new environment. For example, their wingspans differed, and their beak shape adapted to their source of food in their separate environments (ranging from big beaks for seeds to narrow beaks for insects).
