Functions of Organs and Physics Concepts

Biology

• The heart filters waste products from the blood.
• Glaciers shape the land through erosion and deposition processes, forming various landforms.
• The primary source of energy for the water cycle is the Sun.
• Glaciers can create U-shaped valleys, cirques, and fjords through erosion.
• Moraines, drumlins, and eskers are landforms created by deposition from glaciers.
• A river system is a network of food webs and ecosystems.

Physics

• Work is calculated as Work = Force x Distance.
• Pressure is calculated as Pressure = Force / Area.
• The formula to calculate density is Density = Mass/Volume.
• The density of a material can be used to identify it.
• Flow rates of substances can be compared by measuring their relative rates of flow.
• Liquids, gases, and solids can be tested for flow rates.

Oceanography

• Ocean currents and water bodies help moderate temperatures in coastal areas due to water's higher heat capacity compared to land.
• Excessive algae growth in water bodies can result in oxygen depletion and the death of aquatic organisms.
• The extinction of a key species in the food web can lead to cascading effects on other species and disrupt the entire ecosystem.

Chemistry

• Increased temperature results in a faster dissolution rate of a tablet.
• Shorter dissolution time is observed at higher temperatures compared to lower temperatures.
• The pressure acting on a surface area can be calculated using the formula Pressure = Force / Area.
