Answer:Atmosphere
Explanation:
Moon is smaller in size than earth and hence, has very low force of gravity. Moon does not have atmosphere as its weaker force of gravity can not hold the atmosphere. Any present atmosphere on moon would have stripped away by strong solar wind. The weaker magnetic field of moon is one more reason for absence of atmosphere.
Stem cells are cells of the body that can divide and become differentiated. stem cells specialise and take specific functions when an organism grows
mature tissues such as muscle, blood, tissue, bone, nerves, liver all have different types of cells.
they come from three to five day old embryo cells.
they represent potential in the regeneration and repair of damaged tissue. some therapies actually currently use stem cells for this reason
Answer:
Animals get energy from food.
Answer:
it is to do with something called angular moment. Gravity is the central force in the Universe, because it is the only one which has a significant pull over large distances.
A disadvantage of coal to liquid production of synthetic fuels is THAT IT REQUIRES MORE COAL MINING.
The coal to liquid production of synthetic fuels involves the conversion of solid coal to liquid fuel.This can be done either directly or indirectly through chemical processes. The process has many advantages, including: improvement in national and economic security, less dependence on foreign oil, provision of some environmental benefits, such as cleaner oil. But one disadvantage of this process is that it requires extensive coal mining.
