The role of the Golgi body or Golgi apparatus is to package the proteins in vesicles and target it to their respective place of function. Example, the receptor proteins that are synthesised in the Endoplasmic Reticulum will be sent to the Golgi body for its packaging into the vesicles that bind and fuse with the cell membrane. The targeting is done by the special set of markers present on the secreted vesicle. All the eukaryotic cells have a Golgi apparatus. When chemical treatment is done to stop its functioning, the cell stops functioning and eventually dies due to the hampered targeting of proteins to the various organelle. On the other hand, prokaryotic cells lack Golgi body as the cell size is small enough to allow for the synthesised protein to move by diffusion to its target. Hence no effect will be seen when prokaryotic cells are treated with that chemical.
Answer:
insulin; pancreas.
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
Generally, when the blood glucose levels of a person rise, through an endocrine system, the hormone known as insulin is released from the pancreas to convert excess glucose into glycogen, which is typically a short-term energy storage molecule for the body.
In conclusion, the endocrine system maintain homeostasis by releasing insulin from the pancreas to decrease blood sugar and releasing glucagon to increase blood sugar.
This is the primary federal law in the United States governing water pollution. Passed in 1972 the act established the goals of eliminating releases of high amounts of toxic substances into water, eliminating additional water pollution by 1985, and that surface waters would meet standards necessary for human sports and recreation by 1983.
Answer:
The bowl of ice cream contains ice cream with temperature below freezing point. A hot body contains more thermal energy than a cold body. Thermal energy only flows from a hot body to a cold body, and not the reverse.
The bowl of ice cream contain less thermal energy than it sorrounding envoirment (air and the kitchen counter), this creates a temperature gradient that forces thermal energy from the sorrounding envoirment into the bowl of ice cream because, according to thermodynamics, all bodies always tend to be in thermal equilibrium with its sorrounding. The thermal energy flows into the bowl of ice cream until it has the same thermal energy with its sorrounding; bringing the thermal gradient between them to zero.
