Answer:
The difference between a submarine and a submersible is a submarine has enough power to leave port and come back to port under its own power. A submersible has very limited power reserves so it needs a mother ship that can launch it and recover it.A submersible is a small watercraft designed to operate underwater. The term submersible is often used to differentiate from other underwater vessels known as submarines, in that a submarine is a fully autonomous craft, capable of renewing its own power and breathing air, whereas a submersible is usually supported by a surface vessel, platform, shore team or sometimes a larger submarine. In common usage by the general public, however, the word submarine may be used to describe a craft that is by the technical definition actually a submersible. There are many types of submersibles, including both manned and unmanned craft, otherwise known as remotely operated vehicles or ROVs.Submersibles have many uses worldwide, such as oceanography, underwater archaeology, ocean exploration, adventure, equipment maintenance and recovery, and underwater videography.

population pyramids
Explanation:
Population pyramids show the structure of a population by comparing relative numbers of people in different age groups.
Population structures differ markedly between Less Economically Developed Countries LEDCs and More Economically Developed Countries MEDCs.

Usually pyramids are drawn with the percentage of male population on the left and percentage of female population on the right.
It gives us information about birth and death rates as well as life expectancy.
