The answer is cohesion. The high surface tension helps the paper clip (with much higher density) float on water. The property of a liquid that allows it to resist an external force, due to cohesive nature of its molecules. Cohesion refers to the attraction of molecules for molecules of the same kind. Water molecules have strong cohesive forces due to their ability to form hydrogen bond with each other.
Answer: the two tropics zones
Explanation:
Between the two tropics zones, which includes the equator, the Sun is directly overhead twice per year. Outside the tropic zones, whether to the south or north, the Sun is never directly overhead. Two other significant lines of latitude are the Arctic Circle (around the North Pole) and the Antarctic Circle (around the South Pole).
Hi!
An example of a membrane would be Pericardium. This membrane in particular will cover the heart.
What is the Pericardium?
This membrane is a thin, double layered membrane which protects the heart from injuries as well as external blows.In between the membranes, there is a fluid known as pericardial fluid that is present. The function of this is to also protect the heart.
Hope I could help!

Answer:
B. into an aquifer
Explanation:
People can obtain groundwater by drilling a well into an aquifer.
An aquifer is a porous and permeable formation where groundwater can be found.
- Aquifer is usually found below the water table.
- In this regard, the pore spaces of this layer of the earth allows for the storage of ground water.
- When the aquifer is punctured, groundwater can be abstracted.
