Efudex cream:
a) may be used as an anti-infective.
b) should be applied 3-4 times daily.
c) should be applied with gloves or a nonmetallic object.
d) is available as an otc product. answer with

C) Should be applied with gloves or a nonmetallic object.

Explanation:

Efudex is an antimetabolite cream used to treat the skin problem related to cancer that is basal cell cancer and actinic keratoses.  The cream works by inhibiting and death of the fast-growing cell in the skin and thus is antineoplastic in action.

The Efudex is a useful cream that should be used with the precautions and safety measures so it should be applied only 1- 2 times daily, should be used applied by wearing gloves or fingertips or non-metallic objects.

Since the efudex should be applied with non-metallic object or glove, therefore, Option-C is the correct answer.

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.
