B. One
because an independent variable is something you change. So in a scientific experiment you only change one thing. If you happen to change more than one thing then the test becomes unfair therefore you should repeat and make sure that only one thing is changed this time.
<h3><u>Answer;</u></h3>
acceleration= 2 m/s²
<h3><u>Explanation;</u></h3>
From the second Newton's Law of motion the resultant force is directly proportional to the rate of change in momentum.
That is;
F = ma
Thus; F = 100 N, m = 50 kg
a = F/m
= 100/50
= 2 m/s²
Given what we know, we can confirm that if a cancer medicine wishes to stop cellular division, it must target the Centrioles of a cell.
<h3>What are the Centrioles of a cell?</h3>
- The centrioles are cylinder-shaped organelles made up of microtubules.
- Their function is to organize the contents of the cell before cellular division.
- This is done to ensure that once the cell divides, its contents are split evenly to each daughter cell.
- They also play a role in initiating the cellular division process.
Therefore, given the role of the centrioles in organizing the contents of the cell for cellular division, as well as initiating the first part of cell division, we can confirm that in order for a cancer medicine to stop cell division, it must target the centrioles.
