I think it is a good reason cause if the water was bad or not what it claims then 100%of the people would be complaining about it
Option (A) identifies them correctly.
During Meosis 2 daughter cells are formed from a single cell and the chromosomes are equally divided in both the cells.
So, Cell P had 60 chromosome, after miosis 2 daughter cells of each having 30 chromosomes formed, and again after Miosis of from each of those 2 those daughter cells, 2 more daughter cells are formed with equal naumber of chtomosome which equals 15.
Explanation:
To find the number of atoms in each specie, we consider the coefficient and the subscript of each of the given atoms.
1. NaCl:
Na = 1 atom
Cl = 1 atom
2. CO₂
C = 1 atom
O = 2 atom
3. O₂
O = 2 atoms
4. C₆H₁₂O₆
C = 6 atoms
H = 12 atoms
O = 6 atoms
For the second part;
1. 2NaCl
Na = 2 atoms
Cl = 2 atoms
2. 3CO₂
C = 3 atoms
O = 6 atoms
3. 4O₂
O = 8 atoms
4. 2C₆H₁₂O₆
C = 12 atoms
H = 24 atoms
O = 12 atoms
The correct answer is B: The cells will have 2n chromosomes and be diploid.
Diploid cell have two of each chromosome, one from each parent. When diploid cell undergoes mitosis, the result is two identical diploid cells (when haploid cell undergoes mitosis the result is haploid cell). This means that during the mitosis, cells reproduce genetically identical copies of themselves.
