Answer:
Diffusion is the process in which molecules and ions move from a region of high concentration to low concentration. Its also how cells transport waste out of the cell and nutrients into it hence being very crucial. Diffusion also occurs without the expenditure of extra energy using a procedure known as passive transport. (Osmosis is a form of diffusion but deals with water exclusively).
Examples of where diffusion is important;
In the intestines - Digested food molecules such as amino acids and glucose move down the concentration gradient from the intestine into the bloodstream. Wastes such as carbon dioxide or urea travel via diffusion from the body's cells to the bloodstream.
Osmosis plays a major role in living organisms. It aids in the transportation of nutrients from cells to cells and also helps to remove the waste's metabolic products from the cell. The purification of blood in the kidneys is also dependent on the process of osmosis.
Explanation:
because at is formed,the lighter part floats on the surface and the really heavy part (like iron and nickel in the core)sank to the middle
The ongoing active collision of the Indian and Eurasian continental plates challenges one hypothesis for plate motion which relies on subduction. ... The collision and associated decrease in the rate of plate movement are interpreted to mark the beginning of the rapid uplift of the Himalayas.
Metallic bonds do have shiny surfaces (hence, the name metallic).
Metallic bonds are good conductors of electricity.
Metallic bonds cannot be dissolved in water.
The correct answer is option A.
