yanalaym [24]

Answer:

Option B. 10

Explanation:

If 1 mol of butanol contains 6×10²⁴ atoms of H, let's calculate the amount of H.

(number of atoms  / NA)

6.02 x 10²³ atoms ___ 1 mol

6×10²⁴ atoms will occupy (6×10²⁴ / NA) = 9.96 moles

H, has 10 moles in the butano formula.

il63 [147K]

Explanation:

Mitosis and Meiosis are forms of cell division. They use the same steps for cell division which are Prophase, Metaphase, Anaphase and Telophase.

Mitosis produces 2 diploid cells while Meiosis produces 4 haploid cells.

Meiosis stages -

  • Interphase
  • Prophase I
  • Metaphase I
  • Anaphase I
  • Telophase I
  • Prophase II
  • Metaphase II
  • Anaphase II
  • Telophase II
  • Cytokineses

Mitosis stages

  • Prophase
  • Prometaphase
  • Metaphase
  • Telophase
