Alik [6]

Answer:

The (rough) endoplasmic reticulum

Explanation:

The endoplasmic reticulum is a system of interconnected membranes that functions in the synthesis of several membrane-related proteins and lipids. There are two types of endoplasmic reticulum in the eukaryotic cell;

  • Smooth endoplasmic reticulum
  • Rough endoplasmic reticulum

The smooth endoplasmic reticulum is actually smooth because it has no ribosome attachment while the rough endoplasmic reticulum appears rough due to the attachment by ribosomes.

<em>Therefore, the name of the specific organelle that is studded with ribosomes in eukaryotic cell is endoplasmic reticulum.</em>

Soloha48 [4]

The highlighted vessels branch into arcuate arteries.

Arcuate arteries- The interlobar arteries bend over to produce imperfect arches at the point where the cortex and medulla meet. The arcuate artery is the name given to this portion of the blood supply as a result. The arcuate artery divides into several tiny radial arteries, which diverge at right angles and provide blood to the cortex.

Vessels- In the blood, vessels (canals) move waste away from organs and tissues and carry nutrients to those tissues. The vasculature's participation in oxygenating the organism serves as one of its main functions and important roles.
