Waxy endosperm (wx), virescent seedling (v), and shrunken endosperm (sh) are all recessive mutants in corn. waxy and shrunken are both on chromosome 9, located 18 map units apart. virescent is on chromosome 5 and is not linked to the other loci. a strain of corn that is homozygous for waxy and virescent is crossed to a strain that is homozygous for shrunken endosperm. the f1 were entirely wild type. an f1 individual was then test crossed to a strain that is homozygous for waxy, virescent and shrunken. of 1000 offspring, how many of the offspring will be virescent and shrunken, but not waxy?

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.
