Brain structure that controls the autonomic nervous system is the hypothalamus of the brain. It is located on lower part of the top end of the brain stem. The hypothalamus specifically important for maintaining homeostasis, the proper balance of the body’s internal environment such as body temperature, blood sugar, breathing. Thus, the hypothalamus maintains homeostasis by controlling the autonomic nervous system.
The FedEx of the cell are the vesicles.
Vesicles are the structures in which many cell materials are packed and transported. Vesicles are cellular organelles that are composed of a lipid bilayer and they function as cellular envelopes to transport cell materials from one place to another inside the cell.
An example of one material is protein. After a particular protein has been synthesized in the ribosomes of the cell, it is packaged in a vesicle called a transport vesicle. The vesicle carries this package to the Golgi apparatus for final tweaking after which it is again repacked in a new vesicle which transports it to its required destination in the cell.
Answer: Y goes to proteins.
Explanation:
Enzymes, which are a form of protein, are used by the cell to accelerate chemical reactions.
