Fossil evidence of several species has been found linking modern-day whales to their ancient land mammal ancestors. this series of fossils provides evidence for

a) adaptive radiation because the whales retained most of the skeletal shape and structure of their ancestors
b) co-evolution because the different mammals evolved together to interact with the changing environment
c) gradualism because one species evolved slowly and steadily over time by small genetic and physical changes
d) punctuated equilibrium because one species evolved into several related species over a long period of time

climate change and pollution

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
