Answer:

The inactivation of one protein that slow down the cell cycle could lead to cancer. (option b).

Explanation:

The cell cycle is the process a cell undergoes when it divides during its life. This process includes a control mechanism to prevent normal cells from replicating more than normal, called cell cycle regulation.

In oncogenesis - the formation of malignant tumours - many factors induce the abnormal growth of a tissue by the abnormal multiplication of the cells that form it, leading to cancer. One of these factors may be a mutation in the DNA that prevents the production of regulatory proteins.

The mutation that produces exaggerated cell growth -and which can eventually lead to cancer- can create defects in a specific regulatory protein that slow down the cell cycle, so that exaggerated and uncontrolled cell replication occurs.

Once a tumor tissue has formed, successive mutations will lead to a lack of cell differentiation, the property of forming blood vessels, the ability to invade tissue and lose its apoptosis mechanism, that characterizes cancer cells.

Why do dolphins kill more people every year than sharks?
Alik [6]

Answer:

Dolphins use their strong snouts as a powerful weapon to ram sharks, targeting their soft underbellies and gills to cause injuries. Sharks pose less of a threat to larger members of the dolphin family. Indeed, orcas are the top predator in the ocean and small sharks are a target for some populations.
