Breaking down of ATP or of the ATP returns the myosin molecule to the high energy conformation.

Hydrolysis

Explanation:

Actin is a protein that forms thin filaments which are part of the contractile apparatus in muscle cells. In these cells contraction is triggered by the interaction between actin filaments and myosin filaments that produces their movement relative to one another, a process that requires adenosine triphosphate (ATP). In the first place, myosin-ATP binding causes myosin heads to release actin. Subsequently, ATP hydrolysis induces a conformational change in the myosin filament, thereby myosin 'walks on the actin filament' as the muscle is contracted. After ATP hydrolysis, myosin filaments return to its high-energy configuration.

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.
