Unlike strong bases such as sodium hydroxide or calcium hydroxide, it does not cause harm to the skin. It is commonly used in baking, medicine (antacids), and cleaning, showing its safe and versatile basic nature.
When zinc metal is placed in blue copper sulphate solution, a displacement reaction occurs because zinc is more reactive than copper. Zinc displaces copper from its salt, forming zinc sulphate, which is colourless in solution. Copper gets deposited as a reddish-brown layer, while the solution losesRead more
When zinc metal is placed in blue copper sulphate solution, a displacement reaction occurs because zinc is more reactive than copper. Zinc displaces copper from its salt, forming zinc sulphate, which is colourless in solution. Copper gets deposited as a reddish-brown layer, while the solution loses its blue colour. Hence, the correct answer is (b) Colourless.
The phloem plays a vital role in the transport system of plants. It is responsible for translocation, the process of transporting prepared food, mainly sucrose, from the leaves (where photosynthesis occurs) to different parts of the plant. This transport occurs in both upward and downward directionsRead more
The phloem plays a vital role in the transport system of plants. It is responsible for translocation, the process of transporting prepared food, mainly sucrose, from the leaves (where photosynthesis occurs) to different parts of the plant. This transport occurs in both upward and downward directions to supply energy to growing regions such as roots, shoots, flowers, and fruits. Phloem consists of specialized cells like sieve tubes and companion cells that facilitate this movement with the help of energy in the form of ATP. Thus, phloem ensures proper distribution of nutrients, supporting growth, storage, and overall functioning of the plant.

Yes, several states celebrate livestock festivals. For example, Pola in Maharashtra, Kanuma in Andhra Pradesh and Khaturva in Uttarakhand. These events honour farm animals, especially bulls and cows, who help in ploughing, transport and milk production. Farmers decorate and worship animals, offer food and give them rest. Such traditions show respect for animals, express cultural gratitude and highlight the strong human-animal bond essential for agriculture and rural life.

Animal husbandry is the science and practice of managing livestock such as cattle, goats, sheep, pigs and poultry. It involves feeding, sheltering, breeding and healthcare of animals. Farmers provide nutritious food, clean water and safe housing. It also includes vaccination and medical treatment to prevent diseases. Ethical animal husbandry ensures animals live in a healthy environment, increasing productivity in milk, meat, wool, eggs and farm labour while respecting animal welfare.
