In biochemistry, aligand is a substance that forms a complex with a biomolecule to serve abiological purpose. In protein-ligandbinding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein.
Receptor mediated endocytosis is an endocytotic mechanism in which specific molecules are ingested into the cell. The specificity results from a receptor-ligand interaction. Receptors on the plasma membrane of the target tissue will specifically bind to ligands on the outside of the cell. An endocytotic process occurs and the ligand is ingested.
A very well studied example of receptor mediated endocytosis involves the metabolism of cholesterol.

Answer: strip mining
Strip mining is the process of removing the soil and rock above a surface. This process is followed by the removal of the exposed mineral too. Some techniques in strip mining are also called as the area mining or the contour mining.
Answer:
As earth’s temperatures increase with climate change, the polar ice caps melt and the sea levels rise, leaving islands like Australia at risk of flooding and partial, permanent underwater submersion.
