Pancreatic cells, which secrete a large amount of digestive enzymes, are labeled with radioactive leucine and then chased for se
stiv31 [10]

Answer:

On the exterior of the cell.

Explanation:

The black spots as mentioned in the given case would appear on the exterior of the cell after three hours, which suggests that the proteins or the enzymes had been discharged from the pancreatic cell. The mentioned method of labeling and then chasing the component is known as a pulse-chase experiment.  

In this experiment, the labeled compounds are used to follow the dynamics of cellular pathways and procedures. The molecules in a cell get produced and degraded spontaneously at various rates. These changes in the localization of the molecule and its expression levels with time can be determined by exposing or pulsing cells to a labeled compound.  

After this the cells are exposed sequentially to the same compound unlabeled, the process is termed as the chase. The compounds are generally labeled with fluorescent dyes or radioisotopes.

What is the difference between plankton, nekton and benthos?
Archy [21]
<span>The common difference between the three organisms is the area in which they specifically live or stay in the ocean. Planktons can’t be seen by the naked eye and they require microscopes to be detected. Planktons usually float in the water and they cannot move on their own that’s why they are dependent in the movement of the water.

Nektons are organisms that swim through the water and they live in different depths in the ocean ecosystem. Nektons are composed of fish and other mammals that propel themselves through the water.

Benthos are organisms that live in the ocean floor and many of these organisms stay in one place by attaching themselves to rocks. This adaptation protects them from crashing waves and drastic water movements. Other benthos are known to burrow in the ocean floor either for food or protection.</span>
