Fossils provide scientists with evidence that allows them to hypothesize how living organisms have evolved over time. Tiktaalik roseae was a unique organism that has been shown to be 375 million years old. It has been nicknamed the
"fishapod" because it is believed to be a common ancestor of both fish and tetrapods, the first four-legged animals.
How would a scientist study the relationship between the Tiktaalik roseae and modern fish and tetrapods?
create a diagram that hypothesizes ancestry
use relative dating
use transitional fossils to determine age
review its analogous structures

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.  

a symbiotic relationship with the mitochondria
