The third law of motion says: for every action, there is and equal and opposite reaction. In the case of the octopus, this is nicely demonstrated with it's method of travelling. The octopus makes an action, which is it shooting water at high rates in a certain direction, and the equal and opposite reaction is that the octopus's shooting of water in certain direction, moves him into the opposite direction with the rate that it is shooting the water.
        
             
        
        
        
Answer: The question is is incomplete, here are the options.
A. Separating the two groups decreases the chance that the two groups will diverge
B. Traits that form in one group from evolutionary forces quickly spread through both populations
C. Forces like natural selection and genetic drift affect the genes of the two subgroups differently
D. Gene flow is increased in the two subgroups that are formed
The correct Option is C.
C. Forces like natural selection and genetic drift affect the genes of the two subgroups differently.
Explanation:
Forces of natural selection and genetic drift affect the genes of the two subgroups differently because there are differences In the way they are natural selected and genetic drift.
Natural selection is the different phenotype or traits developed by different organisms who h make them to adapt, survive and reproduce than others in their environment. The two sub groups have different phenotype Expressed which cause them to develop different trait.
Genetic drift refers to change or variation in frequency of genes in animals overtime. Genetic drift occur at different rate in different population of organsim which lead to development of different trait in the subgroup.
