Humans have
an exoskeleton
jointed appendages
segmentation
no coelom

The correct answer for the blank is-  Jointed appendages.

Appendage can be described as a part of the body that usually depicts an outgrowth in the body of an organism. Example- Legs, arms, fingers

Human beings have jointed appendages. These appendages possess bones that are linked to each other with the help of skeletal muscles, which are attached to cord like tendons that in turn are linked with bones of the appendages.

Therefore, jointed appendages is the right answer.

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.
