While pet rabbits can survive alone without another bunny living with them, they can get very lonely and sad, as rabbits are naturally herd animals. No matter how much human attention they receive, that does not replace attention from a fellow rabbit friend. 
When one rabbit is introduced to another rabbit, they may not always get along. However, they will always be very curious when they first meet, and can become close friends after bonding for a while. Keeping close supervision on bunnies when they first meet, however, is very crucial, as they could get into a fight and hurt each other.

Humans use selective breeding to pass desired TRAITS on to the next generation of organisms. 
Hope this helped!
        
             
        
        
        
<span>contractile vacuole
Contractile vacuoles are organelles that are responsible for excretion function. They perform osmoregulation which manages wastes, water and other needed materials in the cell. They are found in some prokaryoric organisms like the algae, protists, amoeba and other unicellular organisms.

Fossil fuels are definitely non renewable (such as coal and gas) because they cannot immediately be replenished.
Elements such as wind and water are renewable because they're natural and are regularly produced
