Science follows the evidence where it leads, and pseudoscience starts with the conclusion, and works backwards to confirm it
The mechanisms of reproductive isolation prevent the reproduction of two individuals from different species. The prezygotic mechanisms disrupt the stages of reproduction before the forming of the zygote or prevent the mating at the start, and the postzygotic mechanisms affect the stages of reproduction after the forming of the zygote.
So, the first and the third example (the urchins and the grasshoppers) show the prezygotic mechanism, as the two individuals are not able to mate or form a zygote.
The second and the fourth example ( zonkey and the death of a zygote) show the working of the postzygotic mechanisms, as the zygote is formed, but it seems to be inviable, and the zonkeys are sterile, preventing the individual to reproduce.
Yes it is true because after many years of water or wind eroding away at the rock will cause it to break up into tiny pieces
Answer:
No
Explanation:
This species that we would be killing off is innocent and not volunteering for this.
It wakes up the hormones in your body so you can reproduce in the first place, and it also helps to mature and prepare your body, and your cells, so it is able to reproduce. By waking up those hormones, your body is able to perform reproductive processes
