The dry cleaning industry is the primary user of the chemical perchloroethylene (PCE). The research done by the researchers at the Boston university have found that the PCE chemical increases the risk of developing mental illnesses in the people working with it. Since, it is a common name in the dry-cleaning industry, the workers in this industry are much more prone to mental illnesses a compared to other people.
Hence, the answer is 'dry cleaning industry'.
Answer:
The correct answer is e. Golgi apparatus
Explanation:
Golgi apparatus are also known as Golgi bodies and it bound by only a single membrane. It is present near the endoplasmic reticulum in the cell. Golgi apparatus is composed of 5-8 membrane-bound sac-like structures called cisternae.
The Golgi apparatus plays important role in the modification of molecules like proteins and lipids. The unprocessed proteins that are released from the endoplasmic reticulum enter the Golgi apparatus and in the Golgi apparatus its modification like glycosylation and phosphorylation occurs.
Then these processed proteins are released outside from the Golgi in vesicle forms which have a signal molecule that guides it to various locations in the cell or towards the plasma membrane from where it can move out of the cell.
Therefore the correct answer is e. Golgi apparatus.
The fact that choanoflagellates and collar cells of sponges resemble each other support the inference that chonoflagellates and sponges are sister groups.
Choanoflagellate are single -celled aquatic flagellate with single flagellum surrounded by a collar of microvilli. In addition choanoflagellate have a long interested evolutionary biologist due to their striking resemblance to collared cells of sponge.
D .............. im pretty sure its this one :)
