The duplication of centrioles occurs at the same time as DNA duplication for the cell cycle; that is, in the S phase of interphase.
Answer:
11.7 g in 1 L of water.
Explanation:
Molarity (M) or Molar concentration is a measure used in chemistry for solutes in a solution.
It is defined as mol/ L (number of moles per litre).
0,2 M means we have 0,2 mol/ L
In order to know how many grams this means we need to look up the molecular weight of the solute. In this case NaCl: 58.443 g/mol
= 
X= 
X= 11.69 g
The solution has 11.69 g of NaCl in 1 L of water since its an adequate polar solvent for NaCl dissolution.
Carbon has 4 electrons in its valence shell, thus making 4 covalent bonds.
<h3>How is the Lewis structure?</h3>
The Lewis structure shows the formation of bonds in a molecule, as well as the atoms involved and the valence electrons of each of them. Atoms form chemical bonds with each other in order to achieve electronic stability.
With this information, we can conclude that Carbon has 4 electrons in its valence shell, thus making 4 covalent bonds.
