Tsunami

 

Tsunami

  • These are a series of waves usually generated by the movement of the seafloor. These movements are caused by different types of geophysical phenomena such as earthquakes, landslides, and volcanic eruptions.
  • The word tsunami is a Japanese word, represented by two characters: tsu, meaning, "harbor", and nami meaning, "wave".
  • The tsunami waves behave very differently in deep water than in shallow water as their speed is related to the water depth.
  • They frequently occur in the Pacific, where dense oceanic plates slide under the lighter continental plates. When these plates fracture they provide a vertical movement of the seafloor that allows a quick and efficient transfer of energy from the solid earth to the ocean.

A leaf was plucked from a plant on a sunny day and kept for 2 minutes in boiling water. It was subsequently immersed in boiling alcohol and treated with iodine solution. What will be the final colour of the leaf after the test?

 The final color of the leaf after the described test would likely be a bluish-black color. The process described is a common laboratory experiment known as the iodine test for starch. When a leaf is plucked from a plant, it contains starch. The boiling water breaks down the cell membranes and denatures the enzymes, effectively stopping any metabolic processes. Boiling alcohol acts as a solvent to remove chlorophyll from the leaf. Finally, when the leaf is treated with iodine solution, it reacts with the remaining starch, resulting in the formation of a bluish-black color. This color change indicates the presence of starch in the leaf.

Academic Freedom in India

  Why in News? India has scored considerably low in the international  Academic Freedom Index (AFI)  with a score of 0.352. Academic freedom,  in general, refers to a scholar's freedom to express ideas without risk of official interference or professional disadvantage. Points to Remember:- About the Academic Freedom Index: It has been  published by Global Public Policy Institute  as a part of a global time-series dataset (1900-2019) in close cooperation with  Friedrich-Alexander University Erlangen-Nürnberg, Scholars at Risk, and the V‑Dem Institute. It  compares  levels of academic freedom worldwide and enhances the understanding of its curtailments. The AFI used  eight components  to evaluate the scores: the freedom to research and teach, freedom of academic exchange and dissemination, institutional autonomy, campus integrity, freedom of academic and cultural expression, constitutional protection of academic freedom, international...

If the red blood cells (RBCs) of human blood are isolated and are diluted in normal saline (an isotonic solution to blood), what will happen to the RBCs?

If the red blood cells (RBCs) of human blood are isolated and diluted in normal saline, which is an isotonic solution to blood, the RBCs will remain intact and maintain their normal shape and function. An isotonic solution has the same concentration of solutes as the cytoplasm of the RBCs. When the RBCs are placed in an isotonic solution like normal saline, there will be no net movement of water across the cell membrane. As a result, the RBCs will neither shrink nor swell, and their osmotic equilibrium will be maintained. The shape of the RBCs, typically biconcave discs, will be preserved, allowing them to continue their vital functions, such as carrying oxygen and carbon dioxide throughout the body. In summary, diluting RBCs in a normal saline solution, which is isotonic to blood, will not cause any significant changes to the RBCs, and they will remain functional and retain their normal shape.
