Icefish live in very cold waters (-1.8 degrees celsius) where temperatures are below blood's freezing point. which statements are true about icefish adaptations for cold water?

I found following two statements true for why ice fish live in cold environment.

A. Ice fish have antifreeze proteins, it inhibits blood from freezing.

B. Ice fish do not have red blood cells, which reduces the viscosity of blood, allowing it to flow more freely at cold temperatures.

the answer is a. now keep my answer here.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
