Apopulation of birds, with various size beaks, eats seeds. smail seed can be eaten by birds with small beaks. larger, thicker seeds can only be eaten by birds with larger beaks, thicker beaks. suppose there is a shortage of small seeds but are still many large seeds

With the scarcity of small seeds there will be a drastic change in the population of small-billed birds.

Explanation:

As small-billed birds feed on small seeds, the scarcity of these seeds will cause major problems for this population. In the short term, the population of small-billed birds will decrease, as they will suffer from a lack of food. The rest of the population will go through a process of natural selection and will have to adapt and evolve to be able to feed themselves. Those who are not "selected" will die.

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.
