Radiometric dating method. Geologists commonly used radiometric age-dating to determine the numerical age of rock and fossils based on the natural radioactive decay of certain elements, including potassium and carbon.
Carbon dioxide
carbon monoxide
sulfer dioxide
Active transport is the process by which dissolved molecules move across a cell membrane from a lower to a higher concentration. In active transport, particles move against the concentration gradient - and therefore require an input of energy from the cell.
Answer: Oxygen has a charge of -2 when bonding
The following are the expected ranks of biomes based on increased oxygen for plant growth and they are
1. Desert,
2. Grassland
3. Temperate Forest
4. Tropical Rain Forest
The desert biome is formed owing to very limited annual rainfall and it covers approximately 20% of the Earth. The Grassland is predominantly dominated by grasses while the temperature in the temperate forest is around 10 degree celcius. The plants and trees in this biomes develop special adaptations for their survival. However, the rain forest is characterized with all year round rain hence the biome is moist. The biome is known for vegetations with dense canopies.
