Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. An age could be estimated by measuring the amount of carbon-14 present in the sample and comparing this against an internationally used reference standard. Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable … Read more DMPQ:Short note on radioactive dating.

Directional Movements Directional changes are called tropic movements. Tropic movements are the one which occurs in the direction of the stimulus. Positive phototropism is responding by bending towards the sunlight which can be seen in shoots. Negative geotropism is growing away from the ground which is also shown by shoots. Roots exhibit negative photo tropism … Read more DMPQ- What are directional and non-directional movements in plants?
