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.
Answer:
It made it possible for people to discover and learn about cells.
Explanation:
The cell is the basic unit of structure and function of all living beings. A cell can also be defined as a morphological, functional, and reproductive unit of all living beings.
Every living organism is made up of one or more cells. All cells are created from an existing cell. A cell is the smallest unit that has all the characteristics of life. A set of cells of similar or the same appearance, embryonic origin, and function is called tissue.
The science that studies the cell is called cytology. There are organic and inorganic compounds in the cell. Of the inorganic compounds, water and salts are the most common. Organic compounds in the cell contain carbohydrates, fats, and proteins.
Answer:
Preventive maintenance is where measure are taken beforehand so that the chances of breakdown are minimised resulting in increased efficiency of machines. It is the maintenance that is regularly performed on any equipment to lessen the likelihood of it failing.

Answer from Gauth math
Answer:
Fungi is a unique living organism and it is not considered plant or animal and forms its own kingdom Fungus. On of the most unique features of a Fungi is that its body is composed of thread like structure called Hyphae and produce fruiting bodies, in which spores are formed are help the fungus in reproduction.
Coming towards the question that what is the unique feature of the structure of Hyphae and fruiting body that helps them in their function.
1: Hyphae:
Hyphae are composed of thread like structures called Hypha that are filamentous in nature. Due to its filamentous nature, it helps the fungi to better absorb nutrients from soil and anchor the fungus well in soil.
2: Fruiting body:
The fruiting body is main organ of fungi concerned with reproduction. It has rounded cap like structure in which spores are formed and are disseminated from one place to another and help fungi in reproduction.
Hope it helps!
