density.It can be measured by using jars by measuring the volume of fluid displaced by the stone(put stone into a fully filled jar with water. Measure the volme of water overflown gives the volume of stone.
Hope this helps. :)
Explanation:
Answer:
Partially / semi <u>permeable</u>
Explanation:
Only certain substances can move in cells thus membranes are permeable partially.
Answer:
Explanation:
An aquifer is a water bearing formation within the earth crust.
In Geology, an aquifer is said to be a porous and permeable rock unit.
When an aquifer is over pumped, there is increase in pressure within pore spaces. The increase in pore pressure can lead to the aquifer being damage and a total collapse of the rock's framework. Over pumping aquifers leads to production of more sand and earth materials on water.
It can also lead to total blockage and damage of the aquifer.
Ocean acidification is sometimes called “climate change’s equally evil twin,” and for good reason: it's a significant and harmful consequence of excess carbon dioxide in the atmosphere<span> that we don't see or feel because its effects are happening underwater. At least one-quarter of the carbon dioxide (CO</span>2) released by burning coal, oil and gas doesn't stay in the air, but instead dissolves into the ocean. Since the beginning of the industrial era, the ocean has absorbed some 525 billion tons of CO2<span> from the atmosphere, presently around 22 million tons per day.
This is a scientific fact...
