which structure in the male reproductive tract has a function similar to that of the female fallopian tubes?
the penis
the testes
the vas deferens
the seminiferous tubules

Explanation:

First Question (Vitamin Deficiency)

To determine the deficient vitamin, we analyze the diet:

• Vitamin A: Found in yellow/orange fruits/vegetables (e.g., carrots) and fish, so the student’s diet has sources of it.
• Vitamin K: Primarily found in leafy green vegetables (e.g., spinach, kale). The student avoids most leafy greens, so this vitamin is likely deficient.
• Vitamin C: Abundant in citrus fruits, which the student consumes.
• Vitamin B₁₂: Found in fish and nuts, which are part of the student’s diet.

To find the structure with a function similar to the fallopian tubes (which transport eggs from ovaries to uterus):

• Penis: Involved in copulation and urination, not transport of gametes.
• Testes: Produce sperm and testosterone, not transport.
• Vas deferens: Transports mature sperm from the epididymis to the urethra, similar to how fallopian tubes transport eggs.
• Seminiferous tubules: Site of sperm production in the testes, not transport.

Answer:

vitamin K
