๐Ÿ‘Š 99% of bio students get this wrong ๐Ÿ‘Š
test yourself with our bio misconception of the day by Tutor Wayne ๐Ÿคฉ

Misconception ๐Ÿคฉ
๐Ÿ”  โ€œNatural selection always makes organisms perfectly adapted.โ€


Correct Concept
โญ๏ธ
๐Ÿ”  Natural selection produces organisms that are better suited relative to others in that environment, not perfect.
๐Ÿ” Traits that are advantageous in one environment may be neutral or harmful in another.
๐Ÿ” Evolution is constrained by genetic variation and trade-offs.


Example Question ๐Ÿคฉ
Qn: โ€œExplain why natural selection does not produce perfectly adapted organisms.โ€ (4m)

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

๐Ÿคฉ good job today! ๐Ÿคฉ

๐Ÿฅน โ‰๏ธ take just 2 minutes to correct a bio misconception today! ๐Ÿค”โœจ
by our bio tutor Wayne!

Misconception โ˜˜๏ธ
๐Ÿค” Antibiotics can be used to kill viruses and bacteria.โ€

Correct Concept
๐Ÿ˜† Antibiotics target ONLY prokaryotic features: cell walls (penicillin), ribosomes (tetracycline), or enzymes unique to bacteria.

๐Ÿ˜† Viruses lack these structures โ†’ antibiotics ineffective.

๐Ÿ˜† Viral infections require antivirals, vaccines, or immune responses.


Example Question โœจ
Q: โ€œExplain why antibiotics are effective against bacteria but not against viruses.โ€ (3m)

model ans:
๐Ÿฎ Antibiotics target bacterial structures such as peptidoglycan cell walls or 70S ribosomes.

๐Ÿฎ Viruses lack these structures as they rely on host machinery for replication.

๐Ÿฎ Therefore, antibiotics cannot interfere with viral replication.

โœจ keep going! you are one step closer to your goals today ๐Ÿฆ‘

by our dedicated bio tutor Wayne โญ

Misconception
๐Ÿคฉ โ€œThe body stores amino acids for later, like glycogen or fat.โ€

Correct Concept
โœจ Amino acids are not stored.

โœจExcess amino acids are deaminated in the liver, producing ammonia โ†’ converted into urea (excreted).

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

Example Question
Q: โ€œExplain why amino acids cannot be stored in the body, and describe how excess amino acids are processed.โ€ (4m)

model ans:
๐Ÿคฉ The body lacks storage molecules for amino acids.

๐Ÿคฉ Excess amino acids undergo deamination in the liver, removing the amine group.

๐Ÿคฉ Ammonia is converted to urea for excretion.

๐Ÿคฉ 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 ๐Ÿคฉ

๐ŸŽ€ GP example dump (again) โ˜บ๏ธ

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

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

โœŽแฐ. 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

โœŽแฐ. About 3 million garment workers in Bangladesh sewed garments for the $1.7 trillion fast fashion industry in 2024. The sector is key to Bangladeshโ€™s economy, and contributed 77% of the nationโ€™s $50 billion in exports last year, according to Bangladeshโ€™s Export Promotion Bureau.

โœŽแฐ. Money laundering events in Singapore rose 79 per cent in 2023 from 2022, according to data from financial intelligence and analytics tools provider Moodyโ€™s. Singapore is susceptible to increased money laundering risks, with its open economy and high volume of international transactions

๐Ÿคฉ calling all bio kids๐Ÿคฉ
test your knowledge with this common bio misconception ๐ŸŒŸ
by our bio tutor Wayne ๐Ÿคฉ

misconception
๐Ÿคฉ
โ€œEnergy is released from breaking the phosphate bond in ATP.โ€

correct concept ๐Ÿคฉ
๐Ÿคฉ Breaking bonds requires energy.

๐Ÿคฉ The net energy release comes from the formation of stronger bonds when inorganic phosphate (Pi) is hydrated and bonds form with water and ADP.

๐Ÿคฉ Thus, ATP hydrolysis is exergonic because the products are more stable than the reactants.


example question ๐Ÿคฉ
Q: โ€œATP hydrolysis releases energy that is used by cells. Explain the origin of this energy.โ€ (3m)

model ans ๐Ÿคฉ
๐ŸคฉEnergy is not directly from bond breakage.

๐ŸคฉHydrolysis of ATP to ADP + Pi leads to more stable products.

๐ŸคฉThe 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 ๐ŸŒŸ

๐Ÿ™ƒ ATTENTION ALL GP KIDS ๐Ÿ•
correct a common GP mistake today! ๐Ÿก

๐Ÿ” Mistake: not answering absolute questions with absolute terms๐Ÿ” 
Example question 1: Matcha is the best drink. How far do you agree?

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

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


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

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