si a un cultivo de celulas de la piel se le agrega un inhibidor de la citodieresis , que se podria esperar ?

It is expected that the cells cannot divide and, therefore, the cell line will not survive or will become senescent.  

Explanation:

Cytodiesis or cytokinesis is the process of cytoplasm separation in cell division (i.e., mitosis and/or meiosis) when two daughter cells are formed from the single parental one. The inhibitors of cytokinesis include, for example, caffeine, cytochalasin B, B‐cell linker protein (BLNK), etc. When an inhibitor of cytokinesis is added to one particular cell line it triggers arrest of the cell cycle at cytokinesis phase and thereby, in this case, it is expected that the epidermal cell line will not survive or will become senescent.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
