They replace the lost ions by active uptake through active transport
of ions from the surrounding waters. This is exhibited in freshwater fishes that
actively take in these ions through the gills. Most of the ions involved in osmoregulation in freshwater are those of Na+ and Cl-.
When water vapor condenses to become water again, it is relatively pure.
while it occurs during the water cycle, it can be used to purify water for drinking.
Hope this helps
There are many environmental negative direct outcomes of unused excess nitrogen from nitrogenous fertilizers. One of these is eutrophication. Eutrophication is the excessive richness of nutrients in a water body as a result of fertilizer run offs from the land, which causes a dense growth of plants in the water. Other negative outcomes are: green house effects, acid rain and contamination of underground water which has negative effects on human health.
Answer:
4778.4 cm³
Explanation:
The formulae of finding the volume of a cone = 1/3 * π * r² * h
(r = radius; h = height)
Therefore replacing the variable with values gives = 1/3 * π * 13² * 27
= 4,778.3624261100755157016805859681
Volume to the nearest tenth = 4778.4 cm³
