Explain the role of water potential in the movement of water from soil

It's been a while, but I think I can answer this. Concentration gradients tend to shift from high concentration to lower concentrations for equilibrium. So if the water potential is more in the soil and plant, but less in the air, water will want to travel from the soil, through the plant into the air.

<span>Water evaporates into the atmosphere through the means of transpiration. As the water evaporates, it tends to pull more water molecules up along the xylem. This is known as transpiration pull, where because of surface tension of water and capillary action, water is pulled up along the xylem due to transpiration. This is not the only mechanism of water movement in plants however. </span>

<span>Anyways, from the example of transpiration pull, you can see the role of water potential as the water potential in the soil, being high, flows through the plant, and into the air.</span>

Explanation:

Usually, adaption is triggered by the need to survive and reproduce. Short-term adaption is usually caused by a sudden change in circumstance which causes the need for behavior or tactics to change based on previous experience or knowledge. Long term adaption is different, this usually occurs naturally over the course of many decades in order for the species to have better chances of surviving in the changing environment that they are living in.

Fiesta28 [93]

The question has been answered itself but the answer will contain the detail explanation.

Answer:

1. The replication fork formation during DNA replication is important for the continuity and the addition of the further base pair on the template. The DNA initiation process starts by the formation of replication fork.

2. The okazaki fragments are the short DNA fragments that are formed on the lagging strand. These fragments are later joined by the enzyme DNA ligase.

3. Leading strand is the continuous strand that formed during the DNA replication. The direction of the leading strand is 5' to 3' .

4. DNA polymerase is the main replicating enzyme during the DNA replication process. Different types of DNA polymerase with multiple subunits are present in prokaryotes and eukaryotes.

5. The new DNA that are formed from the parental strand and complementary with each other are called daughter DNA.
