Explain the effect of temperature on surface tension of liquids. [Answer Limit: 20 words] [UKPSC 2023]
The surface tension is highly influenced by the temperature of the liquids. Surface tension typically decreases with increasing temperature as intermolecular forces become less effective. This decrease helps liquids flow more easily, relevant to a broad range of uses from industrial processes to howRead more
The surface tension is highly influenced by the temperature of the liquids. Surface tension typically decreases with increasing temperature as intermolecular forces become less effective. This decrease helps liquids flow more easily, relevant to a broad range of uses from industrial processes to how soap bubbles behave in our daily lives. On the other hand, chill a liquid and you reduce its surface tension, pulling its molecular bonds together, increasing the strength of its cohering forces.

Its uses range from navigation in cars and smartphones, to military maneuvers, surveying, mapping and wildlife tracking. GPS is used in safety applications in aviRead more
GPS is an acronym for Global Positioning System and it is a satellite based navigation system for accurate position and time information. Its uses range from navigation in cars and smartphones, to military maneuvers, surveying, mapping and wildlife tracking. GPS is used in safety applications in aviation and maritime navigation, and emergency response services, as well as for precise timing for telecommunications and financial services.
See lessWhat is the concept of 'Biosphere Reserve'? [Answer Limit: 20 words] [UKPSC 2023]
A Biosphere Reserve is a site designated by UNESCO to promote a balanced development of biodiversity conservation with sustainable use of natural resources. Many of these regions are “living laboratories” of sustainable development, balancing ecological, social, and economic functions. These areas aRead more
A Biosphere Reserve is a site designated by UNESCO to promote a balanced development of biodiversity conservation with sustainable use of natural resources. Many of these regions are “living laboratories” of sustainable development, balancing ecological, social, and economic functions. These areas are subdivided into core, buffer, and transition zones, with the aim of having clear conservation and management objectives and a balanced people–nature relationship.
See lessDefine watershed and mention its importance. [Answer Limit: 20 words] [UKPSC 2023]
A watershed is a region of land that catches rain and snowmelt and delivers it to rivers, streams and lakes. It is essential for water management, flood management, and ecosystem maintenance. Watersheds maintain biodiversity, enhance water-wellness, and are an integral element of sustainable agriculRead more

Immunology is the study of the immune device, and understanding what the body can do in combat to illness is essential to understanding how this frame of workers can perform. it’s far that vital for production vaccines, remedy of autoimmune problems and most cancers healing approaches. Through illuminating the complexities of immune responses and lays the foundations in immunology, ultimately scaling up our strategies in prevention and treatment of a wide range of diseases and lead to the improvement of both global health and longevity.
See lessExplain the difference between active and passive immunity. [Answer Limit: 20 words] [UKPSC 2023]
Adaptive or active immunity occurs when the immune system produces antibodies in response to a germ or vaccine, providing long-term protection. Passive immunity, however, develops when antibodies switch from one person to another, as in maternal antibodies or immunoglobulin remedy, which present rapRead more

Molecular markers are specific sequences of DNA used to distinguish and monitor genetic traits or variations in organisms. They play vital roles in creating genetic maps, diagnosing diseases, and developing breeding strategies, allowing researchers to ensure that specific characteristics can be selected before the breeding process and genetic diversity analyzed. Their purpose is to improve agricultural yields, medical diagnoses, and conservation initiatives, as these genetic signatures offer unparalleled detail.
