The endoplasmic reticulum consists of a network of a tube-like passageway through which proteins from the ribosomes are able to be moved within a cell as the road system allows for movement throughout the city.
I know I'm super late to answering this because it's a two week old question, but I'll just answer it any way lol.
The main reason why modern chemistry is considered scientific is because to confirm their results, scientists use the scientific method.
Answer is: because pH value of solution is changing.
Balanced chemical reaction: NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l).
pH of sodium hydroxide solution is above seven (basic), when solution of hydrochloric acid is added, pH slowly dropping until it became neutral solution (pH is equal seven) and that is endpoint of titration.
Answer:
As there must be twice as many lithium ions as sulphide ions, the 'numbers'
must be different.
It's 4:8. i.e. 4 sulphides around each lithium; and 8 lithiums around each
sulphur.
It's an antifluorite structure.
<h2>Answer:</h2>
<u>Most porous is gravel</u>
<h2>Explanation:</h2>
Porosity tells us how much water rock or soil can retain. It tells us about the spaces among the grains. Gravel is more bigger than sand or silt. Its grains are arranged in such a manner that their integral spaces are very bigger so they are more porous. Clay is the most porous but since it is not mentioned in the option so after clay comes the gravel. Usually gravel and sand has equal porosity.
