Our solar system has one and nearly nine planets in total. The inner planets distance from the sun is relatively closer which in advantage receives solar radiation and heat from the sun more and since these planets are closer to the sun their revolution is shorter as they are nearer to it. According to most studies Venus and Mars were the planets that had possibly incurred life and such planets which have the same leverage as the earth could have sustain and provide lief yet many researchers and astrophysicists suggest that because of the weak atmosphere these plants possess, it has caused them to be more susceptible to the sun's extreme radiation and ultraviolet rays that caused its atmosphere to become thinner and finally was eradicated penetrating the sun's heat unto the surface and absorbing and declining the resources for life.
Answer: Propertys of water that make this bug float on water has to do with the hydrogen bonds that water creates they hydrogen bonds are polar in H2O which creates a dipole dipole effect. Because water has a dipole dipole effect water sticks together and even though it's not necessarily bonding it creates a positive negative force, similar to magnets.
Ammonia is removed from an aquarium system through the use of a biofilter. The biofilter provides a substrate on which nitrifying bacteria grow. These nitrifying bacteria consume ammonia and produce nitrite, which is also toxic to fish. Other nitrifying bacteria in the biofilter consume nitrite and produce nitrate.
