Answer:
a) recovered from pituitary glands removed from human cadavers.
Explanation:
- The human growth hormone is responsible for growth along with cellular proliferation and reproduction in humans.
- The hormone is secreted by the pituitary gland.
- Therefore, before the recombinant DNA techniques were available the hormone was isolated from the pituitary glands fo human cadavers.
- However, this method was not continued because the extract hormone became a source of infection for diseases such as the Creutzfeldt-Jakob disease.
- Therefore, alternatives were looked for and with the advent, in recombinant DNA techniques, the scientist was able to successfully make the recombinant human growth hormone as well.

Explanation:
Answer:
No, se debe a la capacidad de evolucion genetica que tengan los seres vivos frente a los cambios amientales.
Explanation:
Algunos animales frente a cambios ambientales buscan desarrollar mutaciones geneticas que le confieran una cualidad fenotipica que los beneficie en ese medio, es decir como por ejemplo: picos mas largos, plumajes de diferentes cualidades, patas o dedos mas cortos, etc.
Si esta modificacion genetica es capaz de transmitirse a travez de los progenitores de la especie entonces se puede deducir que la especie evoluciono, por ende tiene una adaptacion exitosa y no depende de sus celulas sino del codigo genetico que estas contengan y si son capaces de transmitir dichos genes para poder asi heredar otras generaciones las cualidades fenotipicas ideales.
