The decolourising action of bone charcoal is due to its capacity to -

• A.

• B.

Float

• C.

Oxidise

• D.

Reduce

Explanation
Bone charcoal has the ability to adsorb or attract and hold onto impurities and color-causing substances. This is why it is used in various industries, such as water and air purification, to remove impurities and contaminants. The porous structure of bone charcoal provides a large surface area for adsorption, allowing it to effectively remove color and other unwanted substances from liquids or gases. Therefore, the decolourising action of bone charcoal is a result of its adsorption capacity.

The end of a long bone is connected to another bone by

• A.

Ligament

• B.

Tendon

• C.

Cartilage

• D.

Muscle

A. Ligament
Explanation
Ligaments are strong, fibrous connective tissues that connect bone to bone. They provide stability and support to joints by preventing excessive movement and maintaining proper alignment between bones. In the context of the question, ligaments are responsible for connecting the end of a long bone to another bone. Tendons, on the other hand, connect muscle to bone, cartilage is a flexible connective tissue found between bones, and muscles are responsible for movement rather than connecting bones. Therefore, the correct answer is ligament.

In which type of rocks are metals like gold and copper mostly found ?

• A.

Old Sedimentary

• B.

Old Igneous

• C.

Old metamorphic

• D.

New Metamorphic

B. Old Igneous
Explanation
Metals like gold and copper are mostly found in old igneous rocks. Igneous rocks are formed from the cooling and solidification of molten magma or lava. When these rocks cool and solidify, they can trap and concentrate minerals, including metals like gold and copper. Over time, through geological processes such as erosion and uplift, these rocks can be exposed at the Earth's surface, allowing for the extraction of these valuable metals. Therefore, old igneous rocks are the most likely type of rock to contain deposits of gold and copper.
