The answer is; A
Usually, the oceanic plate is heavier than the continental plate. This is because the oceanic plate is ‘wet’ from the percolated oceanic water in its crust. Therefore, it is submerged by the continental plate, As they collide. the crust (especially the continental plate) folds hence casing uplifting and formation of fold mountains such as the Himalayas.
Answer:
Legume crops improve soil health, they add nitrogen and organic matter to the soil and reduces potential erosion and leaching loss. Legumes may reduce the energy footprint of cropping systems by reducing the need for nitrogen fertilizer, and improve the stability and health of agro-ecosystems.
Beacause some of that web pages have created on the side of the economics and also advertising pages.

Explanation:
Answer:
structure of the plasma membrane
Explanation:
Fluid Mosaic Model:
- The fluid mosaic model, proposed by S.J. Singer and Garth L. Nicolson in 1972,explains the structure and composition of the cell membrane.
- The plasma membrane is a combination of phospoholipids, cholesterol, proteins and carbohydrates.
- According to the model, the plasma membrane is a lipid bilayer made of phospholipids. The bilayer contains a hydophilic end, which interacts with the extracellular matrix and the cytoplasm, and a hydrophobic core that contains phospholipid tails.
- The hydrophobic tails are sandwiched between the hydrophilic phospholipid heads.
- Cholesterol, although less in composition than phospholipids, is an important component of the plasma membrane that provides it its characteristic fluidity and elasticity.
- Proteins are abundantly scattered in the cell membrane. Most of these are transport proteins and transmembrane channels involved in cellular transport.
