C. Oxygen gas
d. Extremely cold temperatures

A. Ultraviolet Radiation

The mutation rates in drosophila will most likely increase after exposure to ultraviolet radiation.

Explanation:

Mutation are spontaneous random sudden changes that occur in the genetic makeup of an organism's. they are changes in the genetic sequence, and they are main cause of diversity among organism

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.
