a. use water that is cold
b.boil the water before use
c. take the water in a clear cup
d. measure the exact amount of water used
Answer:
The correct answer is - C. take the water in a clear cup.
Explanation:
In order to check that if light can pass through the water to which a few drops of black ink have been added Rajan needs to have water in a clear cup or container and put some drops of black ink added to it and place the cup in the light.
There must be a clear cup so it can be observed if the light passes through the ink and reach below the surface covered with the ink as ink spread over the water surface due to surface tension of the water and difference in the density. So to check the light passes or not it requires a clear or transparent cup.
The light intensity decreases with increasing depth of the ocean water. This leads to the division of the ocean into three major zones, sunlight zone, twilight zone, and deep sea zone. The autotrophs like the phytoplankton live in the sunlight zone and perform photosynthesis using sunlight. Various fishes that eat planktons also live in the sunlight zone. The twilight zone is inhabited by various predators like the octopus, sharks and dolphins. Here the pressure of water also is greater. In the deep sea zone, no light is present. Fishes like the angler fish and other bio-luminescent organisms live here. This zone also contains chemotrophs as the producer of food. The pressure of water at this zone is the greatest which is not bearable by the organisms living above it. Thus in this manner light and depth determine the distribution of various organisms in the ocean.
Answer: 60,000 mm2; 1,000,000 mm3; larger
The cell has the same length for all of its side which make it have a cubic shape. The area of 100 mm cube would be: 6 * side * side= 6 * 100 * 100 = 60,000 mm2
The volume of the cube would be: side^3= 100mm^3=1,000,000 mm3
If broken into 10mm cube, it would form 1000 cube. The total area of the cube would be: 1000 * 6* 10 * 10= 600,000 mm2
