Answer 1

Answer:

Animal reproduction is necessary for the survival of a species. ... Asexual reproduction produces genetically identical organisms (clones), whereas in sexual reproduction, the genetic material of two individuals combines to produce offspring that are genetically different from their parents.

You can get the valence electrons in an atom's electronic arrangement by consulting the periodic table:

• The Group 1 atoms have 1 valence electron.
• The Group 2 atoms have 2 valence electrons.
• The Group 3 atoms have 3 valence electrons.
• The Group 4 atoms have 4 valence electrons.
