Answer:
option D is incorrect
Explanation:
the sedimentation coefficient is measured in Svedberg units named after the scientist Theodore Svedberg. the shape of the particle being measured in the ultracentrifuge is one of the factors that determines the sedimentation coefficient. the values are usually not additive as the sedimentation coefficient is based on the rate at which a particle sediments in an ultracentrifuge and not on the size. for example, the sedimentation coefficient of eukaryotic ribosome is 80S but is made up of the 60S large subunit and the 40S small subunit.

The smallest fragments of DNA will be witnessed near the bottom of the gel, on the other hand, the heavier fragments will be visible at the top. The theory behind this is there is a specific pore size on the basis of the concentration of acrylamide/agarose in the gel.

Chloroplasts are found in plant cells only because chloroplasts contain chlorophyll which is essential for photosynthesis. Chlorophyll traps sunlight and uses it to prepare food for plants by the process of photosynthesis.
But my guess its a oxygen? Or carbon dioxide?
