In the year 1850, Rudolf Virchow was studying cells under a microscope, when he observed that cells were dividing and forming new cells. Realizing what he had observed, he understood that living cells reproduce new cells through division. Basing on his conclusion and realization, Virchow proposed that living cells came only from the other living cells.
You can only make one zygote but in some cases the egg splits and makes an identical twin.
Both conduction and induction involve a movement of electrons. Conduction is the transfer of electrons from a charged object to another object by direct contact. Induction does not involve direct contact. Instead, induction is the movement of electrons from one part of an object to another as a result of the electric field of the second object. What is the difference between conductive and non-conductive? Conductive materials are good conductors of heat or electricity. Nonconductive materials are not good conductors of heat or electricity. I hope this helps! :)
Answer:
Due to presence of these structures in ancient as well as modern organisms.
Explanation:
Homologous and vestigial structures are the evidences that show evolutionary relationships between organisms because these structure were also present in the ancient ancestor of that organism. These homologous and vestigial structures shows the relationship between the ancient and the modern organisms. Some structure has a purpose and function in the body of ancient organisms but with the passage of time those structure are useless and have no function in the body but these structure shows connection between modern and ancient organisms.
