Butterflies of the genus colias live in the rocky mountains. Why do they exist in this types of area?

This is because these species of butterflies has two variant of enzymes.which makes them well adapted to the varied range of temperature exposed to in this habitat, and therefore ensures their activity at wide temperature ranges.

Generally, rock mountains has wide range of temperature. Therefore the possession of variant of enzymes ensures sustainable of biochemical reactions for survival of  theses species because of the resistance of these enzymes to high varied  rocky temperature.

Explanation:

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.
