Explanation:

This problem involves medical terminology (word roots and their meanings), which falls under Medicine and Health (a subfield of Natural Science). Let's match each root:

• sept/o: Matches "septum; wall off" (correct as given, likely a pre - matched one).
• sphygm/o: Relates to pulse (e.g., sphygmomanometer measures blood pressure/pulse).
• sial/o: Means salivary gland (so it should match "salivary gland").
• somn/o: Relates to sleep (e.g., somnambulism - sleepwalking).
• sialaden/o: "sial" (salivary) + "aden" (gland), so it also relates to salivary gland (more specific for salivary gland structure).
• somat/o: Relates to body (e.g., somatology - study of the body).
• sigmoid/o: Relates to the sigmoid colon (a curved part of the colon) or the sigmoid shape.
• sinus/o, sin/o: Relates to sinuses (e.g., paranasal sinuses).

For the visible unmatched ones:

• sial/o should connect to "salivary gland".
• sialaden/o also connects to "salivary gland" (more specific, but since "salivary gland" is an option, it's a match).
• somn/o connects to "sleep" (not shown in options yet, but based on roots: somn = sleep).
• somat/o connects to "body".
• sphygm/o connects to "pulse" (not shown, but sphygm - pulse).
• sigmoid/o connects to "sigmoid (colon/shape)".
• sinus/o connects to "sinus".

But focusing on the given options and the visible match for sial/o: sial/o means salivary gland, so it should be connected to "salivary gland". Also, sept/o is connected to "septum; wall off" (as given).

Answer:

• sept/o - septum; wall off
• sial/o - salivary gland
• sialaden/o - salivary gland

(And other matches based on medical terminology roots: somn/o - sleep, somat/o - body, sphygm/o - pulse, sigmoid/o - sigmoid, sinus/o - sinus)
