Reproductive Method </h2>
Explanation:
<em>The rank in order from the most specific which is following .</em>
<em>(1) Reproductive isolating mechanism</em>
<em>(2) Sperm-egg incompatibility in sea urchins</em>
<em>(3) Gametic isolation </em>
<em>(4)Prezygotic isolating mechanism</em>
<em>(1) Reproductive isolating mechanism-</em> The components of regenerative confinement are an assortment of transformative instruments, practices and <em>physiological procedures basic for speciation.</em> They keep individuals from various species from delivering posterity, or guarantee that any posterity are sterile. 
(<em>2) Sperm-egg contradiction in ocean urchins-</em> Bindin is a gamete acknowledgment protein known to control species-explicit <em>sperm-egg grip</em> and layer combination in ocean urchins.
<em>
(3)Gametic isolation - Prezygotic hindrances </em>keep preparation from occurring. Gametic disengagement is a sort of prezygotic hindrance where the<em> gametes (egg and sperm) </em>come into contact, yet no preparation happens. Gametes might be not able to remember each other in various species  
<em>
(4) Prezygotic isolating mechanism- </em>while postzygotic segregation forestalls the arrangement of rich posterity. Prezygotic systems incorporate environment segregation, mating seasons, "mechanical" disconnection, gamete detachment and conduct seclusion.

Answer:  Protein folding and oligomerization
Explanation:
Binding immunoglobulin protein (BiP) is a vital protein present in humans essential for the translocation of secreted peptides. 
BiP is  a molecular chaperone which is present in lumen of ER (endoplasmic reticulum) which binds to the new protein and then translocat into the ER. The protein in ER is maintained under subsequent condition and important for protein folding and oligomerization (conversion of a  monomer or group of monomer into an oligomer). 
Several other functions of BiP are:
- ER translocation
- ER-associated degradation (ERAD)
- UPR pathway
Hence,  BiP is a chaperone, it is important for protein folding and oligomerization.
 
        
             
        
        
        
The rekation between inslin and glucagon is they both secrete a harmones in respone to blood sugar levels,but in opposite fashion.
