The right answer is human embryonic stem cells (hESCs).

Emerging embryonic stem cells are endowed with two important capacities: that of multiplying to infinity, by simple division (self-renewal), and that of giving birth to all types. of cells of the body (pluripotency).  

These properties open up many perspectives, not only for regenerative medicine (including cardiology) but also for the study of genetic diseases and the development of treatments.

In a short essay (100-150 words), describe Darwin's view of how natural selection resulted in
Zinaida [17]

Answer:

Charles Darwin was the man who came with the theory of natural selection. He witnessed finches within the Galapagos Islands and made notes on the similarities and differences of the finches across the group of islands. Each of the islands comprises finches, which were identical, however distinct in different ways.  

Darwin found that the finches appeared to vary on the basis of the food sources available on each of the islands. If the prime food were seeds, the finches seemed to possess thicker beaks in order to break the seeds so that they can consume them.  

On the other hand, if the prime food sources were insects, then the finches seemed to exhibit smaller and pointer beaks so that they could hold the insects readily. In this way, there is unity in diversity. All of these birds are finches and exhibited a common ancestor from which they have originated into the distinct species as mentioned.  

Their variations lie in the habitats, in which they now inhabit. They had to amend with their environments in order to thrive, thus, offering diversity to unity.
