Answer:
Gel-like fluid present within the cell membrane (excluding nucleus) is termed as cytoplasm of the cell.
It serves various functions in the cell such as:
- It supports and hold all the cell organelles and cell parts.
- It serves as the site of most of the cellular activities or processes.
- It provides shape to the cell.
- It contains the cytoskeleton (actin filaments, intermediate filaments, and microtubules) of the cell which helps in maintaining the cell shape, the movement of materials within the cell, cell division and movement of the cell.
Hence, all options are correct except "determines which substances can enter or leave the cell".
Plasma membrane of the cell determines which substances can enter or leave the cell.

Explanation:
Testosterone is a male sex hormone secreted by the testicles which promote the growth of the male reproductive organs and the male characters like muscle buildup.
The hormone shows the paracrine effect and thus act on the target cell at distant. The mechanism of action of the testosterone is that it controls the gene expression of various other genes.

Thus, as a transcription factor is correct.
