Which statement best describes a difference between saturated fats and unsaturated fats? A. Unsaturated fats tend to have higher melting points because they have only single carbon-carbon bonds, which allow the molecules to be straight.
B. Unsaturated fats tend to have lower melting points because they have at least one carbon-carbon double bond, which causes the molecule to bend.
C. Unsaturated fats tend to have lower melting points because they have only single carbon-carbon bonds, which allow the molecules to bend.
D. Unsaturated fats tend to have higher melting points because they have at least one carbon-carbon double bond, which causes the molecule to be straight.

The statement that differentiates unsaturated and saturated fats is "Unsaturated fats tend to have lower melting points because they have at least one carbon-carbon double bond, which causes the molecule to bend".

WHAT IS SATURATED AND UNSATURATED FATS?

Therefore, Unsaturated fats tend to have lower melting points because they have at least one carbon-carbon double bond, which causes the molecule to bend.

B.

Explanation:

Unsaturated fats are fats that have one or more carbon-carbon double bond in their chain. The double bond causes the molecule to bend. The molecules do not stack well, which causes the intermolecular forces to be much weaker than those of saturated fats. This causes the melting points to be lower for unsaturated fats.

Hope that helps.

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.
