How many weeks after fertilization is the placenta formed?
Think it through first, then pick an option.
- a 10
- b 12
- c 14
- d 16
Answer and explanation
Correct answer: b 12
The placenta is formed within 12 weeks after fertilization.
Why the other options are wrong
- a 10: 10 weeks is less than the 12 weeks the book gives for the placenta to form.
- c 14: 14 weeks is more than the 12 weeks the book gives for the placenta to form.
- d 16: 16 weeks is more than the 12 weeks the book gives for the placenta to form.
