BRAINLIEST BET HARRY, Describe the main differences between meiosis and mitosis.

Answer and Explanation:

In mitosis, the parent cell and daughter cells are all diploid. In meiosis, the parent cell is diploid and the daughter cells are haploid. In mitosis, the parent cell and daughter cells are all genetically identical. In meiosis, the parent cell and daughter cells are all genetically unique.

Explanation:

the grams   of   barium that   are in   2.3 x 10^23   atoms of barium   is   52.4 g (answer c)

    calculation

mass = moles   of ba   x molar   mass of ba

  molar mass of ba from periodic table=   137.3 g/mol

  use the   avogadro's law   constant   to   calculate the moles of barium

  that   is     1 mole =   6.02   x 10^23 atoms

                    ? moles = 2.3 x 10^23   atoms

by cross   multiplication

=(1 mole   x 2.3x 10^23 atoms)   / 6.02   x10^23 atoms)=   0.382   moles

mass   is therefore = 137.3   g/mol x 0.382 mol = 52.4 ( answer c)

explanation:

the atomic mass is the bottom number on the element.
