Answer: The answer is ROOT
Explanation: Briophytas belong to the plantae kingdom, therefore they have a cell wall in their cells, and chloroplasts. They have sporangia (structure where the spores are produced and stored) but they do not possess proper roots.

Genetically Modified Organisms, or GMO's are an improvement in efficient agriculture around the world, made possible by biotechnology. People who work in biotechnology worked to create GMO's and they are wildly used all over the world.
1. Note the amounts of atoms of all the component in HNO3, which are 1 atom of Hydrogen, 1 atom of Nitrogen and 3 atoms of Oxygen. Multiply each of the atomic weights by the amount of atoms of each element contained in the compound. Add up the results to obtain the molar mass: 1 + 14 + (16 x 3) = 63 gr/mole.
2. In one molecule of sodium sulfate, or Na2 SO4, there are seven atoms in all.
3. Magnesium dichloride is a magnesium salt comprising of two chlorine atoms bound to a magnesium atom. It is a magnesium salt, an inorganic chloride and a magnesium halide.
