When a beta particle strikes a living cell, __________?
A. the beta bounces off
B. the cell is not affected
C. the cell may cease to function
D. it causes the cell to split
E. a chain reaction occurs
c
When a beta particle strikes a living cell, the correct answer is option C: the cell may cease to function.
To understand why this happens, it's important to know what a beta particle is. A beta particle is a high-energy electron or positron that is emitted during certain types of radioactive decay. These particles have the ability to penetrate matter, including living cells.
When a beta particle strikes a living cell, it can cause damage to the cell's DNA. DNA is the genetic material responsible for all cellular functions. If the DNA is damaged, it can disrupt the cell's ability to carry out its normal functions.
This damage can lead to various consequences for the cell, including cell death, loss of function, or even mutations that can result in diseases such as cancer. Therefore, the cell may cease to function properly when exposed to beta particles.
It's worth noting that the extent of the damage depends on factors such as the energy of the beta particle, the type of cell, and the duration of exposure.
