Explanation:

Question 2

To solve this, we analyze each option:

• Option a (reproductive): The reproductive system is for reproduction, not support/movement. Eliminate.
• Option b (digestive): The digestive system processes food, not related to support/movement. Eliminate.
• Option c (skeletal): The skeletal system (with muscles) provides support, movement, and strength (bones support, muscles move, together give strength). This fits.
• Option d (nervous): The nervous system controls and coordinates, not support/movement. Eliminate.

Analyze each option:

• Option a (respiratory): The respiratory system is for gas exchange (oxygen/carbon dioxide), not hormone secretion. Eliminate.
• Option b (circulatory): The circulatory system transports blood, nutrients, etc., not hormone secretion. Eliminate.
• Option c (endocrine): The endocrine system is made of glands that secrete hormones (e.g., thyroid, pituitary). This matches the description.
• Option d (integumentary): The integumentary system (skin, hair, nails) protects, not hormone secretion. Eliminate.

Answer:

c. skeletal
