The parts which protect the foetus from mechanical injury are labelled I and II.

Gestation refers to the period of pregnancy or the time it takes for female animals, particularly livestock, to carry and develop their offspring before giving birth.

A combine harvester, also known as a combine, is mainly used for harvesting rice. A combine harvester is a versatile agricultural machine that combines several functions into one, making it efficient for harvesting various crops.

If 200 ml of water was poured onto a soil sample in a beaker and 25% of the water drained through the soil, it means that 75% of the water remains retained in the soil.

To find the amount of water retained in the soil, we can calculate 75% of the original 200 ml of water:

Amount of water retained = 0.75 (75%) * 200 ml = 150 ml

So, 150 ml of water is retained in the soil after 25% of the water has drained through.

Transplanting seedlings is a critical step in the cultivation of crops. To ensure successful transplanting and minimize stress on the seedlings, it is recommended to do it early in the morning or late in the evening.

Animal production in agriculture refers to the practice of managing and caring for livestock for various purposes.

The primary purpose of farmstead planning in agriculture is to ensure the efficient utilization of available space. Farmstead planning involves designing and organizing the physical layout of the farm, including buildings, structures, roads, and other facilities, in a manner that optimizes space usage.

The primary purpose of processing facilities in agriculture is to process raw agricultural materials into value-added products. Processing facilities are equipped with machinery and technology to transform harvested crops and other agricultural products into processed goods. This may include activities such as sorting, cleaning, grinding, milling, refining, canning, freezing, drying, and packaging.

A soil profile refers to a vertical section of the soil that displays the different layers or horizons of the soil. It provides valuable information about the composition, structure, and properties of the soil, which is crucial in agricultural practices.

Agricultural ecology is a branch of science that focuses on understanding the ecological processes and interactions within agricultural systems. It involves studying the relationships between crops, livestock, pests, beneficial organisms, soil, water, and the surrounding environment.
