Read each statement and mark the correct response. Remember this is after the wolves were reintroduced.
# Statement True False
1. Wolves had never lived in Yellowstone National
Park before 1995.
2. Before 1995, there were so many deer in the park
that the ecosystem was suffering.
3. The main impact of the wolves was that they ate
a lot of the deer.
4. Plants in different parts of the park regenerated
(grew back) because the deer avoided them.
5. Wolves and beavers create specific habitats for
other plants and animals
6. The number of birds in the park also grew due to
the increased availability of food.
7. The wolves made the rivers go in different
directions.
8. The video shows that just one change can have a
very big impact across a whole ecosystem.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
