Answer:
B. Colloid
Explanation:
Colloid is a mixture that is made up of very small homogeneous particles, thus can not be separated into fractions. Its particles do not settle as other solution, but are evenly dispersed in the medium. Some examples are: liquid milk, jelly, rubber etc
Since colloid is a solution, thus it is made up of two parts; its particles and dispersing medium.
Copper oxide<span> is a base because it will react with acids and neutralise them, but it is</span>not<span> an alkali because it </span>does not dissolve in water. Sodium hydroxide is a base because it will react with acids and neutralise them. It's also an alkali because itdissolves in water<span>.</span>
Because of water's specific heat capacity, it takes longer for the water to heat up. This is useful because if water heated up quickly, then the ocean would be literally boiling, and it would evaporate into the atmosphere.
Note that
1 mi = 1609.34 m = 1609.34 x 10⁶ um
1 h = 3600 s = 3600 x 10⁹ ns
Therefore the speed of the bug is
(3.0 mi/h)*(1609.34x10⁶ um/mi)*(1/3600x10⁹ h/ns)
