Forest logging removes trees, leaving behind only smaller bushes. Some rats in a depleted forest have an allele that makes them smaller than normal rats. It is easier
for the small rats to hide from predators in the bushes.
a) Give two reasons that the rat population is norat Hardy Weinberg equilibrium
b) Which type of rat is selected for in this ecosystem? c) how will the allele frequency change in the rat population d) is this an example of natural selection? Explain. e) has genetic diversity helped or hurt the survival of the rat population? Explain

the answer is d (apex) good luck : ))

where is the scientific experiment?

i need

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.
