The saber-toothed tiger will be clone?

First off, they are not tigers. Smilodon and related species are from a group called the Machairodonts, which is a sister group to modern felines.

But yes, Smilodon fatalis is one of about twenty species that geneticists think that they will be able to clone in the not-too-distant future, together with woolly mammoths, dodo birds, moa, and giant ground sloths.

I’m not sure if that’s possible right now, as in July 23 2020, but it is certainly within the realm of possibility, unlike the cloning of Mesozoic dinosaurs.

I would imagine that a mountain lion would be the surrogate mother, as modern pantherines, though closer in size to sabertooths, are far too rare and valuable to experiment on in this way.

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.
