The answer is Surgical Contraceptive Methods e.g. Vasectomy(For males) and Tubectomy(Females)<span>.
</span>Vasectomy:- In this method vas deference is cutted and tied so that sperms can't reach uthera.
Tubectomy:- In this method both fallopian tubes are cut and tied, so that no egg can head towards the site of reproduction(
Cervix).
Note:- Both process are irreversible.
Answer:
<em>Geographic isolation</em>
Explanation:
Geographic isolation can be described as a term that describes the model of speciation in which a biological population becomes isolated from other members of the population and can no longer have gene flow with them.
The same scenario of gene isolation is occurring in the species of taods which live at the top of the mountains in southern Arizona. This population has become reproductively isolated fro all other species of toads within the mountain range.

Explanation:
Endocytosis is when a substance or particle from the outside is captured and engulfed by the cell membrane until it is in the inside.
Answer:
Its primary role in red blood cells is to maintain levels of red blood cells with low levels of this compound are more suceptible to oxidative damage.
Explanation:
Pentose phosphte pathway helps in the formation of reducing equivalent named NADPH.
The so formed NADPH is used to maintain a normal cellular level of glutathione which act as antioxidant.
As glutathione is not mantained in its normal level, it ability to reduce to adverse effect of hydrogen peroxide is cut down.
As a result cell is more suceptible to oxidative damage.
