Question: Which gas, abundantly produced in swamps and marshes by the action of bacteria on dead vegetation, is commonly referred to as 'Marsh Gas'?
Answer: The gas commonly referred to as 'Marsh Gas' and abundantly produced in swamps and marshes by the action of bacteria on dead vegetation is Methane.
Here is a detailed explanation of why Methane is the correct answer:
- Methane is a colorless and odorless gas that is the main component of natural gas. It is highly flammable and is considered a greenhouse gas.
- Swamps and marshes are rich in organic matter, including dead vegetation. When bacteria decompose this organic matter in the absence of oxygen, they produce methane gas through a process called anaerobic decomposition.
- The bacteria responsible for producing methane are called methanogens. These bacteria thrive in oxygen-deprived environments like swamps and marshes.
- Methane is lighter than air, so it tends to rise and accumulate in the atmosphere above swamps and marshes. It can be ignited and burned, which is why it is often associated with flames in movies or cartoons depicting swamps.
- Methane is also produced by human activities, such as the extraction and transportation of natural gas, coal mining, and livestock farming. However, in the context of the question, it specifically refers to the methane produced in swamps and marshes by bacteria.
In conclusion, the gas commonly referred to as 'Marsh Gas' is Methane, which is abundantly produced in swamps and marshes by the action of bacteria on dead vegetation.

The full form of FM in radio broadcasting is Frequency Modulation.

Process of converting liquid vegetable oil to solid Vanaspati ghee:
Hydrogenation:
- Hydrogenation is the process by which liquid vegetable oil is converted into solid Vanaspati ghee.
- This process involves the addition of hydrogen gas to the vegetable oil at high temperatures and pressures.
- The hydrogen gas reacts with the unsaturated fatty acids present in the oil, causing them to become saturated and solidify.
- This process is usually carried out using a catalyst, such as nickel or palladium, to speed up the reaction.
Benefits of hydrogenation:
- The hydrogenation process increases the shelf life of vegetable oil by making it more stable and less prone to oxidation.
- It also improves the texture and consistency of the oil, giving it a creamy and spreadable quality.
Drawbacks of hydrogenation:
- Hydrogenation can result in the formation of trans fats, which are known to be harmful to health when consumed in excess.
- Trans fats have been linked to an increased risk of heart disease, stroke, and other chronic health conditions.
- To minimize the formation of trans fats, manufacturers have developed partially hydrogenated vegetable oils, which contain lower levels of trans fats compared to fully hydrogenated oils.
Conclusion:
- The process of hydrogenation is used to convert liquid vegetable oil into solid Vanaspati ghee.
- However, it is important to note that excessive consumption of ghee or any oil high in trans fats should be avoided to maintain a healthy diet.

Explanation:
The wax-resist dyeing technique used on textiles native to the island of Java in Indonesia is called Batik.
Details:
Batik is a traditional Indonesian art form that involves using wax to create intricate designs and patterns on fabric. The wax is applied to the fabric using a tool called a canting or a brush, creating a resist that prevents the dye from penetrating certain areas of the fabric. The fabric is then dyed, and the areas covered in wax remain the original color. This process can be repeated multiple times, with different colors and layers of wax, to create complex and vibrant designs.
Batik has a long history in Indonesian culture and is considered a national treasure. It is often used to create clothing, accessories, and home decor items. The designs and motifs used in Batik can vary depending on the region and cultural influences, but they often feature floral patterns, animals, and geometric shapes.
In recent years, Batik has gained international recognition and popularity. It is now appreciated and used by designers and artists around the world, both for its aesthetic appeal and for its cultural significance.

Explanation:
The water drop takes a round or spherical shape due to the physical property known as surface tension. Surface tension is a force that acts on the surface of a liquid and tends to minimize the surface area. It is caused by the cohesive forces between the molecules in the liquid.
Surface Tension:
- Surface tension is the property of a liquid that allows it to resist external forces and minimize its surface area.
- It is caused by the cohesive forces between the molecules in the liquid.
- The molecules on the surface of the liquid experience attractive forces from the molecules below, resulting in a net inward force.
Spherical Shape:
- The surface tension pulls the water molecules towards the center of the drop, causing it to take a round or spherical shape.
- The surface tension acts equally in all directions, resulting in a balanced force that shapes the drop into a sphere.
- The spherical shape minimizes the surface area and, therefore, reduces the surface energy of the drop.
Other Options:
- Viscosity: Viscosity is a measure of a fluid's resistance to flow and does not directly affect the shape of a water drop.
- Polarization: Polarization refers to the alignment of electric dipole moments in a material and is not related to the spherical shape of a water drop.
- Buoyancy: Buoyancy is the upward force exerted on an object immersed in a fluid and does not determine the shape of a water drop.
In conclusion, the water drop takes a round or spherical shape due to the surface tension, which is a physical property of liquids.

Indian Mammal Species: Clouded and Snow
The Indian mammal species referred to as 'Clouded' and 'Snow' belong to the leopard category. They are specific variations or subspecies of leopards found in India. Let's explore more about these species and their characteristics:
1. Clouded Leopard (Neofelis nebulosa):
- Clouded leopards are medium-sized wild cats native to the forests of Southeast Asia, including parts of India.
- They are recognized for their unique cloud-like patterns on their fur, which provides excellent camouflage in their natural habitat.
- These leopards have a stocky build, short legs, and long tails, making them highly adapted for climbing trees.
- Clouded leopards primarily feed on small to medium-sized mammals, birds, and occasionally, reptiles and fish.
2. Snow Leopard (Panthera uncia):
- Snow leopards are large cats inhabiting the mountainous regions of Central and South Asia, including parts of India.
- They are well-adapted to cold climates, with thick fur and a long tail that acts as a balance during their mountainous excursions.
- Snow leopards have unique grayish-white fur with black rosette-like markings, helping them blend into their snowy surroundings.
- Their diet mainly consists of wild sheep and goats, but they may also prey on smaller mammals, birds, and even insects.
Conclusion:
Clouded leopards and snow leopards are two distinct species of Indian mammals. While clouded leopards are known for their cloud-like fur patterns and excellent tree-climbing abilities, snow leopards are adapted for survival in cold, mountainous regions with their thick fur and remarkable agility.
