Rank the following in order from most general to most specific: 1. gametic isolation 2. reproductive isolating mechanism 3. sperm-egg incompatibility in sea urchins 4. prezygotic isolating mechanism

Explanation:

The rank in order from the most specific which is following .

(1) Reproductive isolating mechanism

(2) Sperm-egg incompatibility in sea urchins

(3) Gametic isolation

(4)Prezygotic isolating mechanism

(1) Reproductive isolating mechanism- The components of regenerative confinement are an assortment of transformative instruments, practices and physiological procedures basic for speciation. They keep individuals from various species from delivering posterity, or guarantee that any posterity are sterile.

(2) Sperm-egg contradiction in ocean urchins- Bindin is a gamete acknowledgment protein known to control species-explicit sperm-egg grip and layer combination in ocean urchins.

(3)Gametic isolation - Prezygotic hindrances keep preparation from occurring. Gametic disengagement is a sort of prezygotic hindrance where the gametes (egg and sperm) come into contact, yet no preparation happens. Gametes might be not able to remember each other in various species  

(4) Prezygotic isolating mechanism- while postzygotic segregation forestalls the arrangement of rich posterity. Prezygotic systems incorporate environment segregation, mating seasons, "mechanical" disconnection, gamete detachment and conduct seclusion. 

d is the answer

sorry if its wrong!

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .
