2. small glands that produce sperm.
3. the sac that contains the testes.
4. tubes that extend from the epididymis to the urethra.
5. small tube used for urination.
6. the external sexual organ of the male.
7. a mixture of sperm and fluid.
8. when the penis fills with blood and becomes larger and harder
9. forces the semen through the urethra and out of the body
10. when a boy releases semen in his sleep

Explanation:

This problem is about the male reproductive system, so the subfield of Natural Science - Biology (specifically human anatomy/physiology) applies. We match each description to the correct male reproductive structure:

1. The male reproductive cell is Sperm (from the table's first row, "Testicle" column? Wait, the table has columns: Testicle, Sperm, Scrotum, Urethra, Penis, Vas Deferens, Semen, Erection, Ejaculation, Nocturnal Emission. Wait, the left column is numbered 1 - 10, right column is the description. Let's list the structures and their functions:

• Sperm: male reproductive cell (matches 1)
• Testicle: small glands that produce sperm (matches 2)
• Scrotum: sac containing testicles (matches 3)
• Vas Deferens: tubes from epididymis to urethra (matches 4)
• Urethra: small tube for urination (matches 5)
• Penis: external sexual organ (matches 6)
• Semen: mixture of sperm and fluid (matches 7)
• Erection: penis fills with blood (matches 8)
• Ejaculation: forces semen through urethra (matches 9)
• Nocturnal Emission: releasing semen in sleep (matches 10)

Answer:

1. Sperm
2. Testicle
3. Scrotum
4. Vas Deferens
5. Urethra
6. Penis
7. Semen
8. Erection
9. Ejaculation
10. Nocturnal Emission
