Answer:
Jet streams are very important during the weather prediction and other related aspects.
Explanation:

- Meteorologists get help from jet streams to forecast weather by their position examination.
- They also carry great importance in air travel because flying in or out of them can greatly decrease the time of travel in air and fuel usage too.

During G1 interphase cell growth happens; a rapid cell growth and production of organelles. Energy releases protein synthesis and specific functions.
Answer:
Pepsinogen is produced by chief cells and is activated by hydrochloric acid secreted by parietal cells.
Explanation:
Pepsinogen is a proenzyme produced in the chief cells (that are located in the stomach lining) that, when gets activated, is transformed into pepsin - a peptidase with the function to degrade proteins into amino acids.
The reason why pepsinogen is released inactive is that it would break down all of the cell's proteins because of its proteolytic nature. For this reason, it is released as a proenzyme and gets activated when reaches the acidic environment provided by the hydrochloric acid secreted by the parietal cells, also in the stomach lining.
The answer is an open system
