How did the discovery of Glossopteris support Wegener's continental drift?
Because identical fossils were found on two continents far apart, it suggested that at one time the two landmasses were joined together. In other cases of lands separated by far less distance, plants did not propagate across the divide.

When the continents separated some of the same species ended up on a different continents this was due to?
The continents used to all be connected, which means animals were free to roam. If they were free to roam, then they obviously spread out throughout the continent. So when this continent separated, the same species ended up on new continents because they had originally spread out.
How did Pangaea form into separated continents?
millions of years ago pangea was all the continents put together it got separated because of tectonic plates.
When the continent separated some of the same species ended up on different continents this was due from?
When the continent separated some of the same species ended up on different continents. This is because the continent was so large the species were distributed across the continent. So, when it split, some were on one side and others of the same species were on the other side.
How identical twins can be different when they have the same DNA?
Because they separated into separate beings early in the cell division process. After that, a quadrillion factors are involved in the minuscule differences all along the development process. This is how they become different people.
Identical twins separated at birth and raised in completely different cultures would be most likely to have similar?
Appearance and basic behavior
Why permian fossils are important in understanding plate tectonics?
Paleontologists use a land bridge between continents to explain the existence of identical fossils that are spread out on separated land masses. They contend that the continents were once connected but have since drifted apart.
What group of identical cells that can survive alone if separated are called what?
independent organisms
What is mitois?
During the cell cycle, mitosis is the process by which a cell duplicates into two genetically identical daughter cells. During mitosis, chromosomes in the cell nucleus are separated into two identical sets
Why are chromosomes pairs of DNA?
When chromosomes are visible, they exist as replicated DNA, so each chromosome consists of two identical sister chromatids, which will be separated during mitosis to form two new identical daughter nuclei.
Why did Wegner think continents moved?
Alfred Wegener proposed the theory of continental drift because he observed evidence such as similar geological features, matching rock layers, and identical fossils on continents that are now widely separated. Wegener suggested that these observations could be explained by the continents drifting apart over millions of years.
When do The cytoplasm and two nuclei that are formed during mitosis are separated into two identical daughter cells?
Telophase and cytokenisis
Paleontologists noticed that these were the same on different continents even through the continents were separated by oceans?
Animals
Non-identical twins are called?
Fraternal twins are created when 2 separate eggs are fertilized. Identical twins are created when 1 fertilized egg splits into 2. It is impossible for one identical twin to be male and the other female. Identical twins are usually the ones that look exactly alike.
When the continents separated some of the same species ended up on different continents this was due from?
Plate tectonics
Is a twix bar a homogeneous mixture?
No, A twix bar would be considered a heterogeneous mixture. The cookie and the caramel (not to mention the chocolate) can be physically separated from each other and they are not identical. By definition, a homogeneous mixture must be uniform (or identical) throughout the sample. Twix is not uniform.
