Respuesta :

Answer:

B) Cells reproduce without limit.

C) Cells reproduce with multiple layers.

D) Cell reproduction never stops.

Explanation:

I just did the assignment on Edge2021 and these are the correct answers. :D

When cancer cells are cultured in a petri dish, then these cells reproduce without limits, reproduce with multiple layers and reproduction never stops.

  • Cancer cells are cells that proliferate (divide) in an uncontrolled manner both in vitro (Petri dish) and in vivo conditions, thereby leading to the development of groups of tumoral cells.

  • In cancer cells, the cell cycle is accelerated and mechanisms required to control the progression of the cell cycle are defective.

  • In consequence, cancer cells reproduce without limits and cell divisions never stop.

  • Moreover, when cancer cells are cultured in a petri dish, they can also form cellular attachments known as focal adhesions in order to reproduce with multiple layers.

In conclusion, when cancer cells are cultured in a petri dish, then these cells reproduce without limits, reproduce with multiple layers and reproduction never stops.
