Answer:Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly. Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly.Semipermeable membranes, also termed selectively permeable membranes or partially permeable membranes, allow certain molecules or ions to pass through by diffusion.

The presence of fecal coliform in aquatic environments may indicate that the water has been contaminated with the fecal material of humans or other animals.

Explanation:
The function of Helicase in the process of DNA replication is to untwist the double helix and separating the two DNA strands. This action of helicase creates the replication forks and replication bubbles where the process of replication is initiated. Their main role is the separation of double-stranded DNA into single strands allowing each strand to be copied during the process of replication. It may also function in other cellular processes where the double-stranded DNA must be separated, including transcription and repair. <span />
