Question

Quick easy? Need an explanation please help?

Answer 1

Calculate the percentage of the cell cycle spent in each stage.
Number of cells in given stage ÷ total number of cells counted × 100 = % of the cell cycle spent in this stage

Answer 2

I can't really wrap my head around what they mean by this.

Answer 3

I'm not sure if you are wanting an explanation or how to do it, but if you plug in whatever you are trying to figure out to the formula above then you would get your answer.

Answer 4

Stage Number of Cells in Part 1 Number of Cells in Part 2
Interphase 34 49
Prophase 8 13
Metaphase 3 4
Anaphase 2 3
Telophase 2 4
Cytokinesis 1 3


I have this, and in part 1 there are 50 cells and in part 2 there are 75

Answer 5

So for part 1, interphase would it just be: 50÷34×100=147%?

Answer 6

Where did you get the 50 from?

Answer 7

there are 50 total cells in part 1.

Answer 8

I'm sorry. I thought I could help you but I'm not too sure on how to do it myself.

Answer 9

so that is a "stage".

Answer 10

oh ok

Answer 11

yeah XP

Answer 12

I think what you said was right.

Answer 13

Okay so why would it be 147%? shouldn't it be under 100?\

Answer 14

It should be but Im not sure how to get it.

Answer 15

you are doing it upside down. you want part/whole to get a fraction. then multiply by 100 to get a percent

Answer 16

the idea is 34 out of 50 cells are in "interphase"

as a fraction that is 34/50 (34 out of 50
in percent, we will find it to be 68%

Answer 17

What would you do with the x100

Answer 18

to change a fraction to a percent you multiply the fraction by 100
for example 1/2 is 50%. to figure that out we would do
\[ \frac{1}{2}\cdot 100 = 50 \% \]

in this case\[ \frac{34}{50} \cdot 100= 34\cdot 2 = 68\%\]
