An organ is a body structure composed of tissues that have related functions. The human body has levels of organization. <span>The cell is the basic structural and functional unit of a living organism which communicates with different and similar cells in order to work together and carry out all physiological processes. <span>Cells with similar structures are grouped together in a tissue to perform a shared function. A group of tissues forms an organ that together with other organs make organ system. The integrated activity of all the organ systems makes the whole organism.</span></span>

All carbohydrates are made up of monosaccharides.
Explanation:
The carbohydrates are one of the crucial naturally occurring chemicals when it comes to the survival and prosperity of the living organisms. They serve lot of different roles, from providing energy, storing energy, fertilization, make up the RNA, strengthening the immune system etc.
The carbohydrates though are not all the same, and they can actually be divided into four different groups: 
- monosaccharides
- disaccharides
- oligosaccharides
- polysaccharides
Each of them has different chemical composition, thus having different properties. Those different properties in turn result in different types of usages for each of them among the living organisms. The smallest units, the monosaccharides and disaccharides are actually the ones that are referred to as sugars, something that we all know very well and use it on daily basis.
 
        
             
        
        
        
Answer:
Even when equilibrium is reached, particles of a solution will continue to move across the membrane in both directions. However, because almost equal numbers of particles move in each direction, there is no further change in concentration
