Points to Remember: ABO blood group system Rh factor Antigen and antibody interactions Implications for blood transfusions Introduction: Human blood is classified into different groups based on the presence or absence of specific antigens on the surface of red blood cells. The most important system for blood typing is the ABO system, which categorizes blood … Read more Why is blood group O-negative considered a universal donor? Explain the reason for it.

Points to Remember: Photovoltaic effect Semiconductor materials (Silicon) p-n junction Electron-hole pair generation Current flow Efficiency limitations Introduction: Solar cells, also known as photovoltaic (PV) cells, are devices that convert sunlight directly into electricity. This conversion is based on the photovoltaic effect, a phenomenon where light energy is absorbed by a material, causing electrons to … Read more Explain the working mechanism of a solar cell.

Points to Remember: Geological factors (rock type, slope angle, etc.) Climatic factors (rainfall, snowmelt, etc.) Human activities (deforestation, road construction, etc.) Triggering mechanisms (earthquakes, heavy rainfall events, etc.) Introduction: The Himalayan region, a geologically active and highly mountainous area, is prone to landslides and avalanches. These catastrophic events cause significant loss of life and property, … Read more What are the main reasons for landslides and avalanches in the Himalayan region? Mention them.

Points to Remember: Ozone layer depletion is primarily caused by human-made chemicals. Chlorofluorocarbons (CFCs) and other ozone-depleting substances (ODS) are the main culprits. The depletion is most severe over Antarctica (the “ozone hole”). International cooperation is crucial to address this environmental challenge. Introduction: The ozone layer, a region in the Earth’s stratosphere (approximately 15-35 km … Read more Mention the causes of ozone layer depletion.
