When does the embryo begin to move its limbs? 1. After the first week of conception 2. Immediately after the formation of external genitalia 3. Soon after the formation of the nervous system 4. After 14 weeks of conception

Option-4

Explanation:

After conception during the third week, the fertilized eggs get implanted where the embryogenesis takes place in the uterus. After the fourth week, different types of the cell gets formed like kidney, nerve cell and others.

After 8th to 10th week, the arms and legs begin to grow and after 14th week the muscle and bones grow. This allows the baby to move and stretch their bodies in the womb. This takes place during the 15-16 week of the pregnancy

Thus, option-4 is the correct 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.
