Answer:
<em>The correct answer choice is: B</em>
Step-by-step explanation:
<u>Culture A</u>
Initial number of cells = 1000
The number of cells is raised by 200 each day and every day thereafter.
So, the number of cells raised in one month(30 days)
Thus, the total number of cells in culture A at the end of one month will be:
<u>Culture B</u>
Initial number of cells = 1000
The number of cells is increased by 8% each day and every day thereafter.
<em>Formula for exponential growth is:</em> , where
Initial amount,
Final amount,
Rate of growth in decimal form and
Time duration.
Using the above formula, the number of cells after 30 days will be.....
That means, Culture B is more effective in promoting cell growth.
