Why are plants only found in the upper layer of the coastal zone

There are no plants in this zone.

Explanation:

Because of the lack of light for the plants to perform photosynthesis. Octopus, squid, and the hatchet fish are some of the animals that can be found in this zone. Many animals in this zone have thin bodies that help them hide from predators.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
