Explanation
Egg Formation and Zygote Development in Reproduction
Steps:
- Identify egg formation: Ova develop in the ovaries through oogenesis.
- Locate zygote formation: Fertilization of egg by sperm occurs in the fallopian tube, forming the zygote.
- Match to diagram labels: Assume 2 labels ovaries (egg site) and 1 labels fallopian tube (zygote site).
- Select option aligning with these sites: Eggs in 2, zygote in 1.
Why C is correct:
- In female reproduction, eggs form in ovaries (site 2) and zygote forms via fertilization in fallopian tubes (site 1), per standard human anatomy.
Why the others are wrong:
- A: Places eggs in 1 (fallopian tube, incorrect; eggs mature in ovaries) and zygote in 2 (ovaries, incorrect).
- B: Places eggs in 1 (fallopian tube, wrong) and zygote in 3 (uterus, where implantation occurs post-zygote formation).
- D: Places zygote in 3 (uterus, incorrect; zygote forms earlier in fallopian tube).
Final answer: C
