As the clump of colored fluid at the bottom of the lava lamp reaches the top, which has increased? its density its temperature the kinetic energy of its molecules the space between its molecules

Option A, its density

Explanation:

A lava lamp consists of two liquids which have density close to each other and are insoluble as well into each other. Now when heat is applied at the bottom of the lava lamp, the heavier liquid absorbs heat and become less dense. As it density reduces it starts flowing and rises up in the lamp. As the liquid rises it becomes cool and its density rises. With the increase in density, this liquid again settles down.

Thus option A is correct

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

it enhances antibody production by t cells of the adaptive immune system.
