👊 99% of bio students get this wrong 👊
test yourself with our bio misconception of the day by Tutor Wayne 🤩

Misconception 🤩
🔠 “Natural selection always makes organisms perfectly adapted.”


Correct Concept ⭐️
🔠 Natural selection produces organisms that are better suited relative to others in that environment, not perfect.
🔠Traits that are advantageous in one environment may be neutral or harmful in another.
🔠Evolution is constrained by genetic variation and trade-offs.


Example Question 🤩
Qn: “Explain why natural selection does not produce perfectly adapted organisms.” (4m)

Model Ans:
➡️ Selection acts on existing variation, not creating new traits.
➡️ Traits are compromises (e.g., long legs in cheetahs increase speed but reduce stability).
➡️ Environments change; what is adaptive now may not be later.
➡️ Natural selection favors relative advantage, not perfection.

Misconception ☘️
🤔 Antibiotics can be used to kill viruses and bacteria.”

Correct Concept
😆 Antibiotics target ONLY prokaryotic features: cell walls (penicillin), ribosomes (tetracycline), or enzymes unique to bacteria.

😆 Viruses lack these structures → antibiotics ineffective.

😆 Viral infections require antivirals, vaccines, or immune responses.


Example Question ✨
Q: “Explain why antibiotics are effective against bacteria but not against viruses.” (3m)

model ans:
🍮 Antibiotics target bacterial structures such as peptidoglycan cell walls or 70S ribosomes.

🍮 Viruses lack these structures as they rely on host machinery for replication.

🍮 Therefore, antibiotics cannot interfere with viral replication.

✨ keep going! you are one step closer to your goals today 🦑

Misconception
🤩 “The body stores amino acids for later, like glycogen or fat.”

Correct Concept
✨ Amino acids are not stored.

✨Excess amino acids are deaminated in the liver, producing ammonia → converted into urea (excreted).

✨The carbon skeleton is converted into glucose (gluconeogenesis) or fat.

Example Question
Q: “Explain why amino acids cannot be stored in the body, and describe how excess amino acids are processed.” (4m)

model ans:
🤩 The body lacks storage molecules for amino acids.

🤩 Excess amino acids undergo deamination in the liver, removing the amine group.

🤩 Ammonia is converted to urea for excretion.

🤩 The carbon skeleton can enter respiration (as pyruvate or Krebs cycle intermediates) or be converted into lipids/glucose.

keep going! you are doing so well 🤩

🎀 GP example dump (again) ☺️

✎ᝰ. McKinsey research sizes the long-term AI opportunity at $4.4 trillion in added productivity growth potential from corporate use cases

✎ᝰ. More than six in ten (62%) consumers believe companies are engaging in greenwashing according to the 2025 Capgemini Research Institute report

✎ᝰ. Uber users in Atlanta are canceling rides with human drivers until they match with one of Waymo's self-driving cars. To find a Waymo, a user has to turn down about 20 human Uber drivers on average. This has led a significant decline in available gigs for human Uber drivers, as Uber users seek to experience the technological novelty

✎ᝰ. About 3 million garment workers in Bangladesh sewed garments for the $1.7 trillion fast fashion industry in 2024. The sector is key to Bangladesh’s economy, and contributed 77% of the nation’s $50 billion in exports last year, according to Bangladesh’s Export Promotion Bureau.

✎ᝰ. Money laundering events in Singapore rose 79 per cent in 2023 from 2022, according to data from financial intelligence and analytics tools provider Moody’s. Singapore is susceptible to increased money laundering risks, with its open economy and high volume of international transactions

🤩 calling all bio kids🤩
test your knowledge with this common bio misconception 🌟
by our bio tutor Wayne 🤩

misconception 🤩
“Energy is released from breaking the phosphate bond in ATP.”

correct concept 🤩
🤩 Breaking bonds requires energy.

🤩 The net energy release comes from the formation of stronger bonds when inorganic phosphate (Pi) is hydrated and bonds form with water and ADP.

🤩 Thus, ATP hydrolysis is exergonic because the products are more stable than the reactants.


example question 🤩
Q: “ATP hydrolysis releases energy that is used by cells. Explain the origin of this energy.” (3m)

model ans 🤩
🤩Energy is not directly from bond breakage.

🤩Hydrolysis of ATP to ADP + Pi leads to more stable products.

🤩The energy released is due to the formation of stronger bonds during hydration of Pi and stabilization of ADP.


continue going! you are almost at your goal 🌟

🙃 ATTENTION ALL GP KIDS 🐕
correct a common GP mistake today! 🍡

🔠Mistake: not answering absolute questions with absolute terms🔠
Example question 1: Matcha is the best drink. How far do you agree?

❌ Matcha provides many health benefits compared to other drinks
❌ Matcha is the best drink (1) as it provides many health benefits compared to any other drink

✅Matcha is the best drink (1) as it provides unmatched (2) health benefits
compared to any other drink.
your answer should include:
• (1) the extreme term
• (2) justification for why it is the extreme term


Example question 2: Tourism inevitably harms the environment
❌ Tourism harms the environment as it leads to the destruction of natural
habitats.

✅ Tourism inevitably (1) harms the environment as its very operation depends
on heavy footfall (2) to generate revenue, making environmental degradation
unavoidable.
