Which of the following statements best describes why mitosis is important? A. It allows the body cells to grow and repair damage.
B. It helps produce sex cells such as sperm and egg.
C. It allows cells to divide uncontrollably.
D. It ensures that chromatids line up along the equator of the parent cell.

Option A: it allows the body cells to grow and repair damage

it takes on an electronical energy

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
