In a species of frogs Long legs are dominant over short ones, in the
same species, Smooth skin is dominant over bumpy skin. What offspring
would we get if we crossed a female that was heterozgous for legs and
homozogous recessive for skin... with a male frog that was heterozygous
for both traits.
O
4 long/smooth: 4 long/bumpy : Ashort/smooth: 4 short/bumpy
O
8 long/smooth : 8 short/bumpy
O
9 long/smooth : 3 long/bumpy: 3 short/smooth : 1 short/bumpy
O
6 long/smooth : 6 long/bumpy: 2 short/smooth : 2 short/bumpy

Explanation:

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.

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.
