B. Aquaculture means "cultivating small acreages of land."
Explanation:
Aquaculture is the growing of fishes, crustaceans, molluscs, oysters and other marine organisms like algae in a small acreage of farm. Normally, the carryign capacity per acreage would be lower in the natural habitat – like in the oceans- but this is raised substantially in aquaculture due to adopting certain farming techniques. An example is by cycling the wastewater from teh fish tanks to plants that take up the waste as nutrients and oxygenate the water, The water is then recycled back to the tanks as cleaner water reusable by the fishes and teh cycle continues. This cycle ensures the sustainability of the farm even with very little water compared to the natural environment.
Answer:
There are two chloride ions for each calcium ion
Explanation:
The compound has to have an overall neutral charge. Meaning that the positive charges from calcium have to be canceled out by the negative charges of chlorine.
If there are two chloride ions for each calcium ion, the charges would cancel themselves out (2 * -1 would cancel out with +2).
A cell is NOT part of an atom.... Protons have a positive charge, electrons have a negative charge, and neutrons have no charge, they are in atoms, but a CELL is NOT
