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.
By Pleistocene ice age is meant the glacial periods that appeared in the Pleistocene. The Pleistocene is the first epoch of the Quaternary. It is an epoch when there was a so called ''ice age'' on the Earth, or rather a glacial period. During this ice age the planet had much lower temperatures on a global scale. The climate was also much drier. Lot of ocean water was frozen in the ice sheets that were stretching deep into the North American and Eurasian continents, which resulted in much lower sea levels that today as well. The places further north than 40 degrees of latitude were almost exclusively covered with ice, so life was almost impossible apart from some coastline places.
What this is??????????????????
Answer:
To make 500 mL of a solution of PPP 1% w/v you need 5g
Explanation:
A percent w/v solution is calculated with the following formula using the gram as the base measure of weight (w):
% w/v = g of solute/ mL of solution × 100
A 1% w/v means that you have 1 g of PPP per 100 mL of solution
Thus, if you need to make 500 mL of solution you will need 5 g of PPP.
I hope it helps!
