Lichens are prominent on rocky shores.
Answer:
B. Stress caused by forces that stretch an area of the crust made the rock to break
Explanation:
From the picture inserted to this problem, we see a unit that has been severely fractured.
Fracturing results from the brittle deformation of a rock under applied stress.
- Rock fracturing results in the formation of joints and faults.
- We can obviously see different sets of joint sets on the body of the rock in the picture attacked.
- Also, a prominent fault which resembles an extensional fault can also be seen.
- Therefore, the stress caused the stretch of the area which in turn makes the rock the rock to break.
During the second gap, or G2 phase, the cell continues to grow in size and produce proteins necessary for cell division. Microtubules, filamentous internal structures, necessary for separating the chromosome copies are made during this phase. The second internal checkpoint that determines if the cell can continue through its cycle occurs in G2. While the G1 checkpoint checks to verify DNA is error free before replication, the checkpoint in G2 confirms the new DNA is error free after replication
