Answer:

Covering organs within trunk cavities

Lining trunk cavities

Explanation:

Serous membranes are layers of tissue that protect the organs. They prevent the organs from getting damage from friction which can occur as they rub against the cavity walls.

Serous membranes have two layers, the visceral layer and the parietal layer. The visceral layer covers the organs while the parietal layer covers or lines the cavity walls. In between these two layers, you will find a gap or cavity filled with serous fluid.

They cover organs like the heart, lungs, blood vessels (some of them at least), testes and other organs found in the abdominal cavity.

Answer:

The Golgi apparatus plays a central role in molecular transport after biosynthesis.

Explanation:

Transcription occurs in the nucleus during protein synthesis, followed by translation inside ribosomes. Then, new molecules join the endoplasmic reticulum to be folded and modified. In the Golgi, they are tagged and separated into lysosomes for export outside the cell.

The Golgi system comprises of several regions known as cisternae; they act as independent microenvironments where products requiring their own unique conditions are converted into new, stable biomolecules.
