Answer:
Bone marrow, amniotic fluid, and brain 
Explanation:
In the choices, I notice that liver is also a part of Adult stem cells but so are the ones I mentioned.
Adult stem cells are found in small numbers in most adult tissues. To not get confused by embryonic stem cell, adult stem cells are there to replace dead cells throughout the growing process of a human which is also called somatic stem cells but this type of cells helps with the brain, bone and fluid 
Hope this helped :)

Answer:
it mostly controls all activites
Explanation:
the cell is main structural and functional unit of life in an animal body so without an animal cell the body won't function at all
 
        
                    
             
        
        
        
The Cell to Mentee 
A cell is the basic unit of life of a human. The body cell contains cytoplasm in which organelles are present . There is a nucleus found in eukaryotic cell. It contains the genetic material in the form of DNA with proteins and chromosomes. Inside there is nuclear membrane. Outside the nucleus, there are many other organelles like mitochondria, ribosomes, golgi apparatus, endoplasmic reticulum, and many more.    
 
        
             
        
        
        
Using the gas pedal analogy, the proto-oncogene would be an accelerator since they promote cell division and
deregulate apoptosis, while tumor suppressor would
be the brakes since they constrain the progress of the cell
cycle and induce cell apoptosis. An
oncogene is, therefore, when the accelerator
is stuck in down position and the brakes are not working.
