Answer:
Provides body tissues with oxygen
Explanation:
The respiratory system supplies oxygen and removes carbon dioxide from the body, assisting cells in metabolism, acting in conjunction with the circulatory system, providing oxygen to body tissues. In addition, this system is related to smell, that is, our ability to allow odors and also related to speech, due to the presence of so-called vocal folds in one of the organs of the respiratory system.
This system is formed by the nose, nose cavity, pharynx, larynx, trachea, bronchi and lungs.
The maximum efficiency of a machine is less than 100% and is denoted as option C.
<h3>What is a Machine?</h3>
This is referred to as a device which is created to make work easier and multiplies the effect of human effort.
The maximum efficiency of a machine is usually less than 100% due to the factor known as friction which results in energy being lost.

Well, the cell membrane is full of a bunch of little holes. Sort of like a coffee filter.
What does a coffee filter do? Well, you put the coffee in it and run water through it. Then what?
The water is small enough to pass through the filter and bring some of the coffee with it. But the coffee grains are too big to pass through the filter. If we really wanted the coffee grains to get through the filter, we could force them through. Do you want chunks in your coffee? Eww.
Now the cell membrane is the same way, the little things (water, carbon dioxide, oxygen, sugar) are all small enough to fit through the tiny holes in the cell membrane. This is called, "Passive Transport". Because the things can passively float their way in and out of the cell.
Now some other things are too big to fit through, so to make them fit, the cell has to use energy to open itself a little bit more to let them in. This is called, "Active Transport". Because the cell needs to be active and use energy to let those things in.
<span>Now Osmosis is the transfer of water and salts (basically) throughout the cell.
Both Salt and Water are small enough to fit through the Cell Membrane using "Passive Transport".
I've posted this same response earlier, and it is my writing.</span>
