Answer:

Capillary action refers to the motion of the liquid along the solid surface resulting due to the attraction of the molecules of the liquid. Capillary action is used by the plants to bring water up to the roots and then from stems to the remaining parts of the plant. The liquid molecules are fascinated by the molecules present within the stem. This attraction is utilized to assist the water to move up from the ground and to get distributed to all the parts of the plant.  

There are three intermolecular forces that play an essential role in the procedure of capillary action:  

1. Adhesion refers to the procedure of combining one substance with another. In plants, adhesion permits the water to attach with the plant's organic tissues.  

2. Cohesion maintains the molecules of a similar substance to remain in combination. In plants, cohesion makes the molecules of water to stay together.  

3. Surface tension refers to the influence of the intermolecular attraction, which makes liquids to produce a top or outer layer that works like a kind of thin film. Surface tension is accountable for the water drops to attain its shape and for holding the compositions together as plants soak up the water.

Answer: Intermolecular force is what holds molecules together and capillary action is moving of liquid towards upward into a tube that is capillary. So the Intermolecular forces which takes part in capillary action are; for keeping the molecule attached to tube is the adhesive force and the for keeping the liquid molecule together is cohesive force.

In the plants, mositure from soil is taken up from stem which is tube like and to which molecules have strong adhesion.

The value of n, the Hill coefficient, for hemoglobin is about _________ as great as the value for myoglobin.
ludmilkaskok [199]

The value of n, the Hill coefficient, for hemoglobin is about 2 to 3 times as great as the value for myoglobin.

Hill Equation

The two closely related equations that help to explain the binding of macromolecules to ligands are called the Hill equation. It helps to quantify the interaction between various ligand binding sites.

Hill coefficient

It is used to describe the cooperativity of ligand binding. It can be positive and negative depending on the value of the Hill coefficient. If the value of the Hill coefficient is more than one then it exhibits positively cooperative binding and if it is less than one then it exhibits negatively cooperative binding. Then there is the noncooperative binding where the Hill coefficient value is one. As for the hemoglobin and myoglobin, the values are,

  • Hill coefficient of hemoglobin is 2.7 - 3.
  • Hill coefficient of myoglobin is 1.0.

Thus hemoglobin is positively cooperative and myoglobin exhibits noncooperative binding.

How can gel electrophoresis be used to help illegal poaching of great white sharks?
statuscvo [17]

Explanation:

Gel electrophoresis is one simple and cheap laboratory technique used in profiling. In this case, it can be used to identify Great White Sharks using their proteins or DNA. This way, even if the fish is completely mutilated into the meat, the species can still be identified helping policies to be enforced.

DNA or proteins of a sample of suspected meat is processed and passed through gel electrophoresis. The bands that form are then compared with a standard to check if the bands match. A match indicates that the meat is from a Great White Shark.
