Which of the following is true about the chicken egg?
Options
The embryo head forms toward the broad end because maximum pores for gaseous exchange are at the broad end ✓
The air cell is located at the narrow end of the egg
The depth of air cell in freshly laid egg is 5–7 mm
All of the above
Correct Answer: A
Explanation in English
Correct Answer: Embryo head forms toward the broad end because maximum pores are there
All three facts about the chicken egg are correct:
The embryo head forms toward the broad end because the maximum number of pores (for O₂ intake and CO₂/moisture release) are located at the broad end of the egg.
The air cell is located at the broad end of the egg.
The depth of air cell in a freshly laid egg is 1–3 mm (very small; it enlarges with age).
Since the original answer key says 'All the above,' the correct option here specifically addresses the first true statement (as stated in option a).
