Long Answer Questions (Write the answers in your note-book) :
1. Give any five features of good shelter for milch animals.
Answer:
1. The shelter should be clean, dry, and airy (well-ventilated).

Answer:
Varieties: White button mushroom (Agaricus bisporous) and Paddy straw mushroom (Volvariella).
Cultivation Steps:
1. Composting: Prepare compost using wheat/paddy straw and chicken manure kept at 50°C for a week.
2. Spawning: Introduce "mushroom seed" (mycelium) into the compost and let it spread for a couple of days.
3. Casing: Spread a thin layer of soil over the compost to provide support and humidity.
4. Cropping and Harvesting: Small pin heads appear and grow into button stage mushrooms, which are then harvested.
13. Write briefly the processes of (i) wine (alcohol) making and (ii) bread making.
Answer:
(i) Wine Making: Grapes are crushed to extract juice containing sugar. Yeast is added to the juice in a large vessel (without oxygen). The yeast ferments the sugar, converting it into alcohol. This process is called alcoholic fermentation.
(ii) Bread Making: Flour is mixed with water, sugar, and yeast to make dough. The dough is left in a warm place. The yeast multiplies and ferments the sugar, releasing carbon dioxide gas. This gas gets trapped in the dough, causing it to rise (swell). When baked, the gas escapes, leaving the bread soft and spongy.

2. It introduced high-yielding varieties of seeds.
3. It promoted the use of modern agricultural practices like irrigation, fertilizers, and pesticides.
4. It improved the economic condition of farmers and ensured food security for the growing population.
