If you carefully feel a blood vessel that is visible on the inner surface of the forearm and find that it has no pulse. Which vessel is it?

should be the ulnar vein

Explanation:

Veins-The major veins of the forearm are the Cephalic vein, Basilic vein, Ulnar vein, and Median Antebrachium vein. These veins are responsible for returning blood from the forearm back to the heart. There are also many superficial veins that are visible and important for clinical purposes.

Deep veins — The deep veins of the upper extremity include the paired ulnar, radial, and interosseous veins in the forearm; paired brachial veins of the upper arm; and axillary vein. The axillary vein becomes the subclavian vein at the lower border of the teres major muscle.

In anatomy, the ulnar veins are venae comitantes for the ulnar artery. They mostly drain the medial aspect of the forearm. They arise in the hand and terminate when they join the radial veins to form the brachial veins. They follow the same course as the ulnar artery.

Im sorry if Im wrong. Hope this helped though.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
