The series of canals used to transport materials throughout the cytoplasm in the cell is Endoplasmic reticulum. It comprises of the rough endoplasmic reticulum, with the ribosomes attached to its surface and the smooth endoplasmic reticulum( no ribosomes attached)

short answer: The Earths atmosphere
Explanation:
The Earth's atmosphere protects us from the multitude of small debris, the size of grains of sand or pebbles, thousands of which pelt our planet every day. So the probability of a major collision is quite small

Answer:
The correct answer would be divergent evolution showing by homologous organs.
Explanation:
In the illustration human arm, the flipper of the dolphin, wings of bat and forearm of frog are shown. All these four forelimbs have a different function, however, these forelimbs are having the same underlying anatomy.
The organs having basic structure and origin, but different functions are known as homologous organs. These organs point towards the same ancestor from these organisms evolved. They show a case of divergent evolution.
When related species become less similar in order to adapt and survive in different conditions, evolution is called divergent evolution.
Thus, these forelimbs provide evidence for divergent evolution.
