Two critical requirements must be met before light elements, like hydrogen or helium, will fuse and form heavier elements. the two requirements for nuclear fusion are

Explanation:

Nuclear fusion is the union of the protons and neutrons of two atoms to form a single atomic nucleus, of greater weight than those that gave rise to it.

In this process, an amount of energy equivalent to the difference between the binding energy of the new atom and the sum of the energies of the initial atoms is released.

For the fusion process to occur, it is necessary to overcome the electric repulsion force between the two nuclei, which grows in the direct ratio of the distance between them. This is only possible with extremely high temperatures, these reactions are also called thermonuclear reactions.

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.
