Embryonic differentiation is the process of development during which embryonic cells specialize and diverse tissue structures arise.

Explanation:

A cell capable of differentiating into any typeof cell is known as \"totipotent\". For mammals, totipotent includesthe zygote and products of the first few cell divisions. There are also certaintypes of cells that can differentiate into many types of cells. These cells areknown as \"pluripotent\" or stem cells in animals (meristemic cells inhigher plants). While this type of cell can divide to produce newdifferentiated generations, they retain th…

Explanation:

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =

where is the
