Cholesterol is a type of lipid that is important for cell membrane structure.

All of the options listed (virus, bacteria, fungi) are considered living organisms in various contexts.

Sound waves are longitudinal waves, where particle displacement is parallel to wave direction.

Nitrogen is a macronutrient that is essential for the synthesis of amino acids and nucleic acids in plants.

Climate change leads to more frequent extreme weather events, which can adversely affect agricultural productivity.

Methane is a potent greenhouse gas that significantly contributes to global warming.

Chlorofluorocarbons (CFCs) are major contributors to the depletion of the ozone layer, leading to increased UV radiation.

Plastic waste is a significant contributor to water pollution, affecting aquatic life and ecosystems.

A major criticism of the UN Security Council is that it is often perceived to be dominated by Western countries, particularly the five permanent members.

El Niño is primarily caused by changes in ocean currents in the Pacific Ocean, affecting global weather patterns.

All of the above factors—latitude, longitude, and altitude—play a major role in determining climate.

Altitude is a major factor in determining the climate of a region, as it affects temperature and precipitation.

The differential heating of land and water is a major factor in the formation of monsoons, leading to seasonal winds.

Latitude is a major factor in the formation of rainforests, as they are typically found near the equator.

The major factor in the formation of soil is the weathering of rocks.

Carbon Dioxide is a major greenhouse gas that contributes to global warming and climate change.

The Himalayas are a major mountain range in India, known for their high peaks and significant geographical impact.

Sulfur dioxide (SO2) is released from various sources including volcanic eruptions, automobile emissions, and industrial processes.

Urbanization is a major threat to biodiversity as it leads to habitat loss and fragmentation.

The dew point is a measure of humidity, indicating the temperature at which air becomes saturated with moisture.

Dew Point is a measure of humidity in the atmosphere.

Humidity is a measure of the amount of water vapor in the air.

Temperature is a measure of the average kinetic energy of particles in a substance.

Genetic Drift is a mechanism of evolution that involves random changes in allele frequencies, particularly in small populations.

Gene flow is the mechanism of evolution that involves the transfer of genetic material between populations through migration.

All of the options listed (natural selection, gene flow, and genetic drift) are mechanisms of microevolution, which refers to small-scale evolutionary changes within a population.

All of the above mechanisms (cohesion, adhesion, and capillarity) contribute to water transport in plants.

Electroporation is a method used to introduce DNA into host cells by applying an electrical field to increase the permeability of the cell membrane.

All of the listed methods can be used to introduce DNA into plant cells, each with its own advantages and applications.

Electroporation is a method used to introduce foreign DNA into host cells by applying an electrical field to increase the permeability of the cell membrane.
