Answer:
The 5' and 3' polarity restriction
Explanation:
Discontinuous replication is when synthesis of new DNA molecule takes place as a series of short fragments that will subsequently be joined together.
These fragments are called the Okazaki fragments.
DNA synthesis takes place from 3' to 5' end. However due to 5' and 3' polarity. The replication has to be discontinuous due to the synthesis happening backwards and okazaki fragments being formed.

Mediterranean ecosystem with hot dry summer and fire can be found on various continents across the globe. Plants in these ecosystem have evolve similar adaptations to survive these circumstances.
Echidnas are egg laying mammals that live in Australia and new Guinea. They are sometimes known as spiny anteaters since they are covered in spines and mostly eat ants and termites. As such they resemble south American anteaters and hedgehogs but are not closely related to them. Instead echidnas descended from an aquatic platypus like ancestor.
Explanation:
Divergent evolution is a process where different organisms with different anscetors evolve independently and develop similar traits due to their adaptation to similar environment.
Another example is the similarities between hummingbird and hummingbird moth, the evolved from different ancestors and yet posses similar characteristics.
Answer:
The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same. For example, the mass number of argon atoms and calcium atoms can both be 40.
