The part of the brain that is being <span>tested when a police officer asks a DWI suspect to walk a straight line and touch his nose with his finger is the primary motor cortex.
The motor cortex has to do with movement and balance - so obviously, if you need to prove that you can walk a straight line, which involves both of these things, or if you need to move your finger to a certain spot, which also involves both balance and movement, that would be the correct answer.

Answer:
B. secrete granzymes and perforin.
Explanation:
Perforins are the proteins that perforate the plasma membrane of the target cell and lead to bursting of cells due to holes formed in its membrane. Granzymes are the proteolytic enzymes. They serve to stimulate the target cells to kill themselves by the process of apoptosis.
Binding of natural killer cells to their target cells stimulate the release of granules that are filled with perforins or granzymes to kill the target cells.
Likewise, cytotoxic T cells bind to the infected body cells and release the granules filled with perforins or granzymes to kill those infected cells.
