<span>Many planets are made of gas, and in different situations, the atmosphere can be destroyed.
The sun which is burnt measures atmosphere and in the same case planets can be in a good situation on galactic map and a great condition in the atmosphere as well as earth.
For example, the mass of an object can attract a smaller object causing gravity. The bigger the masses of a planet when it is in the right condition the more atmosphere it can attract if there is any floating on the planet. If it is big it will make a gravitational influence and gather more gases.</span>

Answer:
The three fatty acids can be different from one another. Since the hydrocarbon chains are very non-polar, fats do no dissolve in water; instead, fat molecules tend to coalesce with one another. Since a fat molecule has 3 fatty acids connected to a glycerol molecule, they are also called triglycerides.
state the uses of excretory products in plants
Carbon dioxide, excess water produced during respiration and nitrogenous compounds produced during protein metabolism are the major excretory products in plants. Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration.
Hope this helps :)
