Explanation:

Question 76

To solve this, we analyze each option:

• Option a (Cleaning): Matches the definition of removing visible dirt/debris with soap and water.
• Option b (Decontaminating): Involves reducing contamination, not just visible dirt removal.
• Option c (Scrubbing): Is a type of cleaning but not the general term for this action.
• Option d (Disinfecting): Kills germs, not just removes dirt.

Melanocytes are known to produce melanin, a pigment. Analyzing options:

• Option a (stem cells): Melanocytes are not stem cells.
• Option b (pre - cancerous cells): Melanocytes are normal cells, not pre - cancerous.
• Option c (pigment cells): Correct, as they produce pigment (melanin).
• Option d (infection fighters): Melanocytes do not fight infections.

The hair cycle phases:

• Option a (Catagen phase): Is a transitional phase, not resting.
• Option b (Transition phase): Not a standard hair cycle phase name for the resting phase.
• Option c (Telogen phase): Is the resting phase where hair is shed.
• Option d (Anagen phase): Is the growth phase.

a. Cleaning
