in 2011 HKCEE Bio II asked about:
(B) and the thermal expansion of seawater, both of which result in rising sea levels
Examination reports from similar years indicate that students often confused the roles of the loop of Henle and the collecting duct, or incorrectly stated that ADH is produced in the pituitary (it is produced in the hypothalamus and stored/released from the pituitary). Additionally, some failed to link the concept of negative feedback to daily scenarios like drinking seawater or prolonged sweating. Question 49 likely tested these precise points, rewarding those who could apply theoretical knowledge to a practical context. ce bio 2011 ii q49
If you can share the original question text or a photo, I will rewrite this article to match it , including the official answer and explanation.
The pedigree below shows the inheritance of two traits in a family: in 2011 HKCEE Bio II asked about: (B)
The 2011 CE Biology examination, particularly Section II Question 49, typically assessed candidates’ understanding of a cornerstone of human physiology: . While the question likely presented a diagram of the nephron or a graph showing changes in blood plasma composition, the underlying theme is the kidney’s role in maintaining a stable internal environment. This essay will explore the biological principles relevant to that question, including negative feedback control, selective reabsorption, and the action of antidiuretic hormone (ADH).
For those preparing for the current HKDSE, review sites like HKDSE Past Paper by Topic often include CE-era questions for foundational practice. AI responses may include mistakes. Learn more If you can share the original question text
Please send me the or a photo of Q49. I can then:
Explain the between "sticky ends" and "blunt ends."
If you recall the of Q49, describe it (e.g., "a question about the reflex arc diagram" or "a table of enzyme activity"). I will write a complete article as if answering that precise question, including:
Bacteria are used because they reproduce very quickly via binary fission , allowing for industrial-scale production of the hormone.
