Embryonic stem cells have the ability to become all types of cells.
That means that those stem cells can become kidney cells, lung cells etc.
If you nurture these stem cells with healty cells from a tissue or an organ, those stem cells will eventually grow into and become the same as the cells you nurtured the with.
This means that you could use embryonic stem cells to create healthy kidneys, skin and other types of tissues/organs.

its B or D but I guess the most is D
Answer: (B) Pre-zygotic; post-zygotic.
Explanation:
Prezygotic isolation occurs before fertilization of eggs. It occurs between the two sex gametes and deter sexual reproduction between different species.
However, individuals are considered to be diverge on the phylogeny tree and different species, when they cannot reproduce.
Mechanisms of prezygotic isolation include habitat isolation, gamete isolation, mechanical isolation, behavioral isolation, and mating seasons.
Whereas, postzygotic isolation prevents the formation of fertile offspring. This phenomenon leads to production of an hybrid offspring from different species and this is a form of speciation in nature.
Mechanisms of postzygotic isolation include hybrid inviability, hybrid breakdown, and hybrid sterility.
Answer:
The correct answer is - option E.
Explanation:
This result is a mere coincidence since however there are three sorts of stress macrophage phagolysosomes and these three sorts of stressors may have a couple of basic qualities that are activated, and the remaining could be showed or expressed 'in light of the obscure that exclusively has a place with phagolysosomes and macrophages.
Thus, the correct answer is - option E.
The half-life of a radioisotope is the amon the symbol 42He, the subscript 2 is the mass number for helium and the superscript 4 is the atomic number for helium.
