Study Notes
Earth and Life Sciences
- Earth is the only planet in the solar system that gave rise to complex life.
- Human activities have a boomerang effect, causing destruction to Earth's subsystems.
Geology
- Olivine can be scratched by quartz.
- Olivine and hematite belong to the silicates and oxides chemical groups, respectively.
- A geologist would use bracketing to estimate the age of a fossil by measuring the ages of rocks beneath and above it.
- The geologic time scale displays information about the sequence of events and the duration of time periods in Earth's history.
Natural Hazards
- Liquefaction may occur if loosely-packed and water-logged sediments at or near the ground surface lose strength during earthquakes.
- Residents living near the sea are most exposed to the hazard of tsunamis after experiencing a magnitude 8.0 earthquake.
- Geohazards refer to events like earthquakes and volcanic eruptions that pose risks to life and property.
Dating Techniques
- Carbon-14 is not suitable for dating a rock sample because it has a limited age range and is only used for organic materials.
Biology
- Adrenaline is responsible for the fight or flight response in humans.
- The best recommendation for a student to follow during the Covid-19 pandemic is to maintain good hygiene, get enough sleep, and exercise regularly to boost immune system health.
- Ligaments are primarily responsible for holding bones together at joints.
- Adaptation in living organisms is best represented by examples such as the development of antibiotic resistance in bacteria or the camouflage of animals in their environment.
- Gregor Mendel is known as the Father of Modern Genetics for his groundbreaking work with pea plants.
- The structure of DNA is not associated with Gregor Mendel, as his work focused on the laws of inheritance.
