Option A.

It lowers the head.

Explanation:

The ischial arch is a prominent structure closer to the colliculus seminalis of horse. The ejaculatory duct is lateral to this and correspond to the area of ductus differenc eand vesicular gland opening.

The vesicular glands can be easily catheterized using a small-diammeter, flexible polyethylene catheter or a stylet . The catheter is inserted into the instrument channel of the videoendoscope and serves as a route for direct aspiration of fluid or instillation of pharmacologic solutions for direct treatment.It also helps to guide the scope head into the seminal vesicle .

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.
