Answer:

e,

Explanation:

The process is called Embryonic  differentiation. It is the process where  cells of embryo  undergo division to diverse  specialised structures of  tissues and organs during  Embryogeneis (development  of embryo).The differentiated cells are pluoripotent embryonic stem cell.

 The differentiation is important because   different   cell types of specific functions are in the  embryo. In order to  assume their specific  functions for embryo developments and identity, they must be differentiated 'that is  developed and assigned to  perform specific roles.

It is preceded by fertilisation and Cleavage; influenced by the  internal  factors of cells,as well as,  extracellular factors  of the cell medium.

You are a scientist researching West Nile virus, a mosquito-borne pathogen. You note that a number of cases of West Nile disease
icang [17]

       First of all, let's think about the scientific method, and its processes of how it works.

       It all starts with observation, so we need to check all the data we have and all the information that can be collected to have a good thought on what's going on.

        After gathering enough information, let's think about a hypothesis that could help solving this problem. Well, reading the question, we can check that that region passed through the wettest summer in 100 years, and that's the main problem here, because before this weather, was this disease a problem? I guess not, so this can be a reason, the change in the percentage of water in the air.

         With that said, we need to test if this is true or not, and for that, we'll need mosquitoes with the West Nile virus, and we'll put them in different environments, one that it's wet, and another one that it's not that wet, just like the West Nile problem. This way we can check if this is the problem or not, if it's affecting their reproduction and etc.
