Answer:
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants.

Answer:
Properties of life include the use of <u><em>energy</em></u> to power an organisms activities.
Explanation:
Energy is the driving force which allows every cell to perform its functions. Organisms like humans tend to gain energy by the process of cellular respiration. Cellular respiration can be described as a process in which organisms make carbon dioxide and water from glucose (from food) and oxygen (from air). Huge amounts of ATP is also released during this process. In plants, the process of photosynthesis and cellular respiration supplies them with the energy sources. 
 
        
             
        
        
        
Answer:
cells are so small because it is structural functional unit of an organism which can be only seen through microscope
 
        
                    
             
        
        
        
The cell theory consists of:
1. all living organisms are made up of cells
2. cells are the basic structural/organizational unit of all organisms
3. all cells come from pre-existing cells
 
        
             
        
        
        
There are many different ways that cells can connect to each other. The three main ways for cells to connect with each other are: gap junctions, tight junctions, and desmosomes. These types of junctions have different purposes, and are found in different places.
