Answer:
The correct answer is - facilitated diffusion.
Explanation:
Facilitated diffusion is a form of facilitated transport of molecules such as amino acid, glucose, and others through the plasma membrane involving the passive or indirect movement of molecules along their concentration gradient, which is led by the presence of another molecule normally a pore or channel made up of integral protein.
Facilitated diffusion depends on several factors such as the size of molecules, type of molecules, similarity of molecules to extracellular matrix or fluid that slow or fast the diffusion process.
Thus, the correct answer is - facilitated diffusion.
 
        
             
        
        
        
The secondary structure is responsible for the shape that the nucleic acid assumes. The bases in the DNA are classified as purines and pyrimidines. ... A purine base always pairs with a pyrimidine base (guanine (G) pairs with cytosine (C) and adenine (A) pairs with thymine (T) or uracil (U)).

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.
