Chemicals
Why are chemicals used in everyday household items bad for the environment
Create waste, can harm biodiversity and living species
True or false, trees indirectly cool the Earth
As temperatures rise, the body's inability to regulate heat causes this dangerous condition, often fatal in heatwaves.
Heatstroke
What does DNA stand for?
Deoxyribonucleic acid
Antibiotic famously found by accident in a mold
Penicillin
White __ is a highly effective, natural acidic cleaner that can replace harsh bathtub and tile cleaners. (Hint: its chemical formula is CH3COOH!)
Vinegar
Which forest produces the most amount of oxygen?
Amazon Rainforest
The WHO identifies this nutritional deficiency, caused by drought and crop failures, as a major health risk.
Malnutrition
Name the 5 bases of nucleic acids
Adenine, guanine, cytosine, thymine, uracil
What is biomimicry?
Innovating by learning from nature
This chemical is commonly found in household cleaners, glass polish, and fertilizers, and can trigger asthma (Formula NH3).
Ammonia
The __ of trees help prevent soil erosion
Roots
Because warmer, wetter weather expands their range, these insects are spreading illnesses to new regions.
Mosquitoes (or ticks)
Name the molecular formula of ribose (Hint: the ratio is 1:2:1!)
C5H10O5
What is a danger of the overuse of antibiotics?
AMR (antibiotic microbial resistance)
When plastic breaks down, it creates these tiny particles, often less than 5mm in size, that now contaminate food and water.
This plant is common in foods, highly pungent, and can help reduce high blood pressure
Garlic
This type of air pollutant, which causes asthma and cardiovascular disease, is worsened by warmer temperatures and wildfires.
Smog
What is octoploidy?
Eight copies of each chromosome
Modelling after a kingfisher's beak helped engineers solve a technical problem for this vehicle
Japanese bullet train
These products, when disposed of improperly, will leach toxic heavy metals into the environment
Electronics
Spicy compound found in chili peppers (shown to have anti cancer properties!)
Capsaicin
Following floods, the spread of this bacterial disease often increases through contaminated water.
Will accept: leptospirosis, cholera, E.coli, typhoid
In a strawberry DNA extraction, what does the salt do? (Double points if you use polarity in your description!)
Attaches to polar parts of DNA, makes less polar, more hydrophobic
Why can naturally sourced antibiotics be more advantageous than synthetic ones?
Points for any explanation:
Molecular promiscuity
Adaptability
Can target AMR microbes specifically
