Which of the two types of immu-
nity requires white blood cells?
explain.

The acquired or adaptive immunity requires white blood cells.

Explanation:

Acquired immunity acts by destroying the foreign particles with the help of white blood cell called lymphocytes. The lymphocytes – T cells and B cells activates the acquired immunity system.  

The T-cells activates mediated immunity, where they directly destruct the problematic cells like tumor cells. This cell-mediated action is proceeded by different T cells – cytotoxic, suppressor, and helper T cells.  

The B-cells activate humoral immunity by triggering antibody production against specific antigens and by signaling T cell activation. This antibody-mediated action is undertaken by plasma and memory B cells .

the answer is golgi apparatus

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
