Answer:
Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things
 
        
                    
             
        
        
        
Answer:
dependent variable
Explanation:
In an experiment, a line graph can be used to display the results of the experiment. A line graph, which posseses two axis namely: x-axis or horizontal axis and y-axis or vertical axis, can be used to show the relationship between the independent and dependent variables in an experiment. 
The independent variable, which is the variable subject to change is displayed on the X-axis while the dependent variable is displayed on the vertical or Y-axis. 
 
        
             
        
        
        
Answer: Divergence evolution or divergent selection
Explanation:
The divergent evolution/divergent selection can be defined as the process of accumulation of differences between the related populations lies within the species. This process leads to speciation.
This occurs when the two populations of the same species get separated by a geographic barrier. The separated members of the same species experience different selective pressure that are responsible for adaptation in the new environment.

Titan's rivers, lakes, and seas of liquid methane and ethane could provide a habitable environment on the moon's surface, though any life there would most likely be very different from life on Earth.
Methane gas is effective at trapping heat and burns quickly. As a result, methane is one of the most important human fuels. Furthermore, methane in the atmosphere helps to regulate the Earth's climate.
Over the first 20 years after it enters the atmosphere, methane has more than 80 times the warming power of carbon dioxide. Even though CO2 has a longer lasting effect, methane drives warming in the short term. Methane from human activity is responsible for at least 25% of today's global warming.
As a result, methane not only contributes to global warming directly, but also indirectly through the release of carbon dioxide.
