47. What is the function of the polar bodies that are produced during oogenesis?
(A) They are the mechanism that allows for the shedding of excess cytoplasm during the production of a haploid ovum.
(B) They are the mechanism that allows for the shedding of excess nutrients during the production of a haploid ovum.
(C) They are the mechanism that allows for the shedding of excess genetic material during the production of a haploid ovum.
(D) They are the mechanism that allows for the shedding of excess mitochondria during the production of a haploid ovum.
(E) They are the mechanism that allows for streamlining of the ovum so as to facilitate the penetration of an ovum by a sperm.

47. What is the function of the polar bodies that are produced during oogenesis? 卵子生成(Oogenesis)過程中產生的「極體」(Polar bodies)功用為何?

(A) They are the mechanism that allows for the shedding of excess cytoplasm during the production of a haploid ovum. 
❌ 產生單倍體卵細胞時,排出多餘細胞質的機制。
 (B) They are the mechanism that allows for the shedding of excess nutrients during the production of a haploid ovum. 
❌ 產生單倍體卵細胞時,排出多餘養分的機制。
 (C) They are the mechanism that allows for the shedding of excess genetic material during the production of a haploid ovum. 
⭕️ 產生單倍體卵細胞時,排出多餘遺傳物質(染色體)的機制。
 (D) They are the mechanism that allows for the shedding of excess mitochondria during the production of a haploid ovum. 
❌ 產生單倍體卵細胞時,排出多餘粒線體的機制。
 (E) They are the mechanism that allows for streamlining of the ovum so as to facilitate the penetration of an ovum by a sperm.  
❌ 為了使卵細胞流線化,以利精子穿透的機制。
