Diseases are not common on most houseplants grown indoors because environmental conditions are not favorable for plant pathogens to grow and infect the plants. Control of diseases begins with prevention. Always buy disease-free plants. Use pasteurized soil when repotting.
Jupiterâs atmosphere is the largest in the Solar System. Molecular Hydrogen and Helium make up most of its atmosphere as well as small amounts of ammonia, methane, hydrogen sulfide and water.Gases such as nitrogen sulfur, noble gas and oxygen can also be found in the planet.The gaseous part of the atmosphere slowly transitions into the liquid part of the planet.olecular Hydrogen and Helium make up most of its atmosphere as well as small amounts of ammonia, methane, hydrogen sulfide and water.

Mars also has an atmosphere that is primarily carbon-dioxide, but on Mars, the atmosphere is extremely thin, and prone to high winds. The giant outer planets Jupiter, Saturn, Uranus, and Neptune have extremely thick atmospheres of hydrogen, helium, methane, and ammonia. Titan, the moon of Saturn also has a methane-ammonia atmosphere. For reference, Titan has roughly the mass as the planet Mercury (which doesn't have an atmosphere at all).
