A common column material used in size-exclusion chromatography is dextran, a polysaccharide of glucose. Which type of interactio
Yuliya22 [10]

Answer:

Hydrogen bonding

Explanation:

  • A hydrogen bond is a form of the electrostatic force of attraction which takes place between the hydrogen atom and a more electronegative atom such as nitrogen, fluorine, and oxygen. 
  • Hydrogen bond falls in the category of weak forces. 
  • In size-exclusion chromatography, the type of interaction that takes place between the proteins and dextran is hydrogen bonding. 
  • The hydrogen bonding is possible because dextran, being a polysaccharide of glucose has several hydroxyl groups and thus, they get involved in the hydrogen bonding.

The fungus Melampsora lini causes a disease known as flax rust. Different strains of M. lini cause varying degrees of the rust d
Dennis_Churaev [7]

Answer:

Explanation:

Using the Mendelian approach to solve this question, we will understand that the mendelian approach has a pattern for inherited traits.

From the data set given, the total number of the population is:

43+9+32+110 = 194

However, their ratio are being calculated as follows:

43/194 = 0.22

9/194 = 0.05

32/194 = 0.16

110/194 = 0.57

After comparison with the Mendelian's approach, we realize that these results seem to be similar to the 9:3:3:1 ratio.

i.e.  

3/16 = 0.18

1/16 = 0.06

3/16 = 0.18

9/16 = 0.56

The inheritance pattern obviously dictates that the flax experiment proceeds in the pattern found in the Mendelian's Approach and the resistance of the two different strains were arbitrated by two traits.
