Answer:
The absence of cytokinesis after nuclear division forms cells with two nuclei.
Explanation:
Under normal conditions, the division of nucleus by mitosis or meiosis is followed by the division of cytoplasm. The division of cytoplasm divides the cytoplasm among the daughter nuclei. This results in the formation of two daughter cells from one parent cell that has undergone mitosis. However, in the absence of cytokinesis, the cytoplasm would not be distributed among the daughter nuclei and the parent cell would have two daughter nuclei. This is called the binucleate condition as found in the liver cells.

Answer:
Cynognathus fossils were important to Wegner's theory because they were found on lands now separated by a wide ocean.
Explanation:
Wegner used the fossil of cynognathus as evidence to prove his continental drift hypothesis. Cynognathus are reptiles which lacked the swimming ability. These reptiles survived in the land before separation in live form along with other organisms surviving side by side.
Later due to certain natural phenomenon these reptiles died and the land got separated by a wide ocean. The fossils of cynognathus reptiles are now found in the lands that are separated by wide ocean.
