A craton is a large, stable portion of Earth's lithosphere that makes up part of a continent. The Kaapvaal craton in Africa is one of five ancient cratons left from the Precambrian era. The rock has remained tectonically stable since its formation 3.6 billion to 2 billion years ago. What do you think the term "tectonically stable" means? Why do you think this rock formation is important to understanding the history of Earth? Do you think studying ancient rock formations such as the Kaapvaal craton can teach scientists not only about Earth's past but also its future? Why or why not?

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.

option c is the correct answer.

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.
