Answer:
Unicellular organisms consist of only one cell and multicellular organisms consist of many cell.
Explanation:
Living things made up of a cell are called unicellular beings. They are very small and simple. In other words, unicellular organisms are those that are formed only by a single cell in which all the vital functions necessary for life are produced. For this reason, they are mostly microscopic organisms. Examples of unicellular organisms are viruses or bacteria.
Multicellular organisms are made up of a large number of cells. They present, therefore, a greater complexity than unicellular organisms in terms of the functions they develop. All current multicellular organisms come from a single cell, that is, they begin their life being unicellular. That is, they are formed from a zygote. Some examples of multicellular organisms are mammals, fungi, and mosses.
So, <u><em>unicellular organisms consist of only one cell and multicellular organisms consist of many cell.</em></u>
Answer:
B: Adding water, then adding solute
Explanation:
This is because, say you have a solution with a certain concentration.
If you add more water, it will become more diluted (less concentrated)
If you add more solute, it will become more concentrated.
Therefore if you add water and solute, it could cancel out, and the concentration would remain the same.
Hope this helps! Let me know if you have any questions/ would like anything further explained :)
A C that is carbon that occur in greatest number of different oxidation zones
Answer:
Ca(s) + N₂(g) + 3O₂(g) → Ca(NO₃)₂ (s)
Explanation:
The reaction of the formation of Ca(NO₃)₂(s) , is as follows -
Ca + N₂ + O₂ → Ca(NO₃)₂
The above reaction , can be balanced by adding whole numbers ,
Hence , the balanced reaction is as follows -
Ca + N₂ + 3O₂ → Ca(NO₃)₂
The states of the respective molecules is -
the state at which the atoms are most stable or the state at which the atoms are most commonly found .
Hence ,
Calcium is most stable in solid state
Oxygen is most stable in gaseous state
Nitrogen is most stable in gaseous state
hence , the balanced reaction with all the states mentioned is as follows -
Ca(s) + N₂(g) + 3O₂(g) → Ca(NO₃)₂ (s) .
