It starts when a protein starts the unwinding of the DNA helix. Next comes the separation of the DNA strands right before the transfer of genetic data to the newly assembled DNA strands starts. A protein known as helicase is what breaks down the hydrogen bonds between strands of DNA during replication.

What effect would an increase in temperature have on the rate of osmosis in these cells
charle [14.2K]

Answer:

hope it helps you❤❤❤❤

Explanation: Factors Affecting the Rate of Osmosis

Temperature - The higher the temperature, the faster the movement of water molecules across the semi permeable membrane.

Osmosis is the passage of water from a low solute concentration area through a semi-permeable membrane to a high solute concentration area to equalize the solute concentrations on both sides. Meaning of the terms: solute, solvent and solution. A solvent is the base substance, where a solute is being dissolved and the result is the solution. Through osmosis, water is provided to the cells of your body; it plays a significant role in the preservation of life. It is this process that helps plants receive water and is even used in kidney dialysis.
