Answer:
In cancer, cells loss their adhesion because protein expression involved in this process is dysregulated
Studies suggest that cell junctions are critical for cancer progression and metastasis
Finally, cancer cells modify the extracellular matrix since this matrix may act as a barrier for the migration of cancer cells
The three important agents which are involved in chemical weathering are –water,, carbon dioxide and oxygen. Among the three most important chemical weathering agent is water. With a simple formula H2O, the two hydrogen atoms bonded to one oxygen atom. This structure of water gives it a polar molecule property due to which it can polarize itself into negative and positive poles. The hydrogen is the positive pole with (+1) charge while the oxygen is the negative pole with (-2) charge and they attract ions opposite to their charge numbers.This exerts a molecular force on the surrounding molecules and they dissociate to get polarized and form new molecule. This process is called hydrolysis where a mineral is dissolved in water and ions from the minerals are carried away. These elements undergo the process of leaching.
