- Question
Why is Meiosis called Reduction Division?
- Correct Answer
- Meiosis :: Meiosis is a type of cell division that reduces the chromosome number by half in daughter cells, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them Why it is called as Reduction Division :: 1 As the Meiosis division process involves in reduction of chromosome number in the daughter cells to half the number in the parent cell, this process is called Reduction Division Meiosis creates gametes (egg and sperm cells) 2 The resulting gametes have 23 new chromosomes, one member of each of the 23 pairs, representing unique combinations of the original maternal and paternal copies

Correct Answer: Plato
Correct Answer: Enid Blyton
Correct Answer: Reflects green light
Correct Answer: 58.44 gm/mol
Explanation:
To get the mass of a mole of NaCl, we need to add the molar atomic weights of the individual elements i.e, Na and Cl
Atomic weights of Na = 22.99 gm/mol Cl = 35.45 gm/mol
Now, mass of a mole of NaCl = 22.99 + 35.45 = 58.44 gm/mol.
