I got C. it is a homogenous mixture and particles settle down if left undisturbed.
Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. ... The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe.
Recessive traits are masked by dominant traits and are therefore rarely observed.
Solid:
•Has a definite shape and volume.
•It has the lowest energy.
•These are hard to compress.
Liquid:
•Has a definite volume, but take the shape of the container.
•It has medium energy.
•You can compress them a little difficulty.
Gas:
•Has no definite shape or volume.
•They have the highest energy.
•These are easily compressible.
31c-11c=20c So, therefore, the range is 20c.
Hope this helps! :D
