You will conduct an experiment of your own design to investigate thermoregulation in crickets. Which of the following factors would be the most important independent variable (experimentally controlled / varied / manipulated by you) to determine the relationship of temperature and metabolism rate in crickets?
variation in ambient / surrounding environment temperature

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.  

c is the correct answer!
