Muscle hypertrophy occurs when the fibers of the muscles sustain damage or injury. The body repairs damaged fibers by fusing them, which increases the mass and size of the muscles. Certain hormones, including testosterone, human growth hormone, and insulin growth factor, also play a role in muscle growth and repair.
        
                    
             
        
        
        
As the individual body size of an organism increases, the population density for this organism in a given habitat tends to decrease. 
  <span>It has been shown that an inverse relationship between the size of an animal and its local abundance exist. Animals with larger body size have higher energetic requirements, resource exploitation, and susceptibility to predation and thus the competition is bigger. Yet, the density–body size relation depends on the physical complexity of the habitat and population of a species.</span>

Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.
        
             
        
        
        
The answer is actually <u>true</u><u>.</u>
The starting point of all rivers is higher than their end point. However, under the right conditions, small amounts of water can be drawn upwards, against the tug of gravity, through a phenomenon known as "capillary action". For this to occur, however, the water must be confined into a small flow space.
Hope this helps!  If it does, would you mind marking my answer as Brainliest? Thanks :D
