β οΈ SERIOUS NOTE
Please do not use AI to answer the questions.
These quizzes exist for YOUR benefit β to help you identify what you know and what you don't. If you use AI, you're only cheating yourself. Your SPM examiner is not going to let you Google the answer.
And just so you know, if your answer appears suspicious, I will personally ask you to explain it in the discussion group. No AI can save you then.
Answer with what you actually know. If you get it wrong, that's fine β that's how you learn. But don't fake it. π§¬

𧬠SOALAN MALAM INI / QUESTIONS OF THE NIGHT Q1 β Form 4 (Chapter 13: Urinary System) A patient has normal kidney function but is found to have glucose in their urine after a meal. Blood tests show extremely high blood glucose levels. Which best explains this?β¦
When blood glucose is extremely high:
The transporters get overwhelmed
-Not all glucose can be reabsorbed
-So the excess spills into urine β glycosuria
πNow eliminate the nonsense:
A: ADH controls water, not glucose β irrelevant
B: Glucose normally enters filtrate anyway β not damage
D: Mitochondria issue would affect reabsorption generally, but question says kidney is normal

πNow eliminate the nonsense:
A: ADH controls water, not glucose β irrelevant
B: Glucose normally enters filtrate anyway β not damage
D: Mitochondria issue would affect reabsorption generally, but question says kidney is normal
Correct answer:
π C. Blood glucose exceeds the kidney's maximum reabsorption capacity so excess glucose cannot be reabsorbed and is excreted
π C. Blood glucose exceeds the kidney's maximum reabsorption capacity so excess glucose cannot be reabsorbed and is excreted

Q2: Hard level In a food web, a pesticide is sprayed on grass. The pesticide is not biodegradable. Which organism in the food chain Grass β Grasshopper β Frog β Snake β Eagle would have the highest concentration of pesticide in its body and why? A. Grass ββ¦
Q2: Pesticide is non-biodegradable β it doesnβt break down
-Each organism stores it in tissues (often fat)
-When predators eat prey, they inherit all the pesticide from multiple organisms
-Concentration increases at each trophic level
So by the time you reach the top predatorβ¦ congratulations, itβs basically a walking chemical storage unit.

Option check:
A (Grass) β starts the chain, lowest concentration
B (Grasshopper) β higher, but still early stage
D (Snake) β high, but not the highest
C (Eagle) β top trophic level = maximum accumulation π¦
A (Grass) β starts the chain, lowest concentration
B (Grasshopper) β higher, but still early stage
D (Snake) β high, but not the highest
C (Eagle) β top trophic level = maximum accumulation π¦
Correct answer:
π C. Eagle β due to biological magnification, pesticides accumulate and become most concentrated at the highest trophic level
π C. Eagle β due to biological magnification, pesticides accumulate and become most concentrated at the highest trophic level
The higher you go, the worse it gets. Nature really said,
βCongrats on being top of the food chain, enjoy the toxins.β
