Answer:
No I do not think that all of the cells in an animal are the same. All of the cells complete different things. For example, Mitochondria cells break down sugars and other compounds into celluar energy, while the skin cells are busy producing Keratin. This shows that no two cells are exactly the same.
Hope this helps!

Answer: B
Explanation:
The T helper cell needs to acttivate the T cyctotoxic cell in order for the Tc cell to go do its work.
Once the TC cell is active it interacts with MHC-1 proteins on the surface of the infected host cell, this allows the Tc cell to recignise the host cell and begin secreting cytotoxins (perforins and granzymes) in order to degrade the infected cell and cause apoptosis (controlled cell death)
