How can variation and evolution affect a species' survival in an ecosystem? Explain your reasoning in 4 complete sentence. THIS IS THE SECOND TIME ASKING PLZ HELP ME

Explanation:

Variation allows some individuals within a population to adapt to the changing environment. ... Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.

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.
