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".

Answer:
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
The reason that natural selection is important is that it's the central idea, stemming from Charles Darwin and Alfred Russel Wallace, that explains design in nature. It is the one process that is responsible for the evolution of adaptations of organisms to their environment.
