Question

In order to examine the factors that affect the flow of substances across cell membranes permeable bag were partially filled with a fluid.

Bag A contains a 30% dye solution (30% dye and 70% water); the bag was tied and had a mass of 100 grams. The bad was then submerged into a larger beaker of pure water, and at 10-minutes intervals, the bad had a mass of 120 grams. The beaker remainded clear.

Bag B contained pure water. The bag was tied and had a mass of 100 grams. The bag was then submerged into a large beaker of pure water and at 10-minute intervals, removed from the beaker of water and remaster. After 10 minutes, the bag had a mass of 100 grams. The beaker remaind clear.

Problem/question: what was the problem being investigated by the scientists?

Hypothesis/prediction: write a hypothesis that these scientists might have had before designing this experiment.

Independent variable: what are the scientists changing in this experiment?

Answer 1

@Ultrilliam

Answer 2

Well what is affecting what?

Answer 3

Need desperate help!!!!!!

Answer 4

@JustSaiyan

Answer 5

@Sazzie ?

Answer 6

@Falconmaster ?

Answer 7

Im retired

Answer 8

Pls?

Answer 9

I rly need help

Answer 10

Ur my best chance rn. Maybe the only best chance

Answer 11

the independant varrible thingy is the amount of water and or dye

Answer 12

There are more questions too. I’m sorry

Answer 13

you have to do me a favor

Answer 14

Anything

Answer 15

alright

Answer 16

what was the problem being investigated by the scientists?
...
the first sentence/paragraph/section thing of this prompt

Answer 17

factors that affect the flow of substances across cell membranes permeable bag were partially filled with a fluid.

Answer 18

I literally quote: "to examine the factors that affect the flow of substances across cell membranes permeable bag were partially filled with a fluid"

Answer 19

is the problem thingy i think

Answer 20

I WIN BOI

Answer 21

I still don’t get it

Answer 22

Hypothesis/prediction
does the amount of dye to water ratio affect how mass will change

Answer 23

ok, what do you not understand?

Answer 24

the problem is to examine what factors affect the flow of a substance through cell membranes

Answer 25

I am pretty sure that that is just the same picture three times

Answer 26

Damn sorry

Answer 27

I'm gonna keep copy pasting quotes from the prompt, because all the information you need to answer anything is already provided, you just have to dig/read

initial mass of Bag A: "the bag was tied and had a mass of 100 grams"
final mass of Bag B: "the bag had a mass of 120 grams"
mass difference: 120 - 100 = ?
direction of water movement: you ended up with more fluid IN the bag in the end, so point towards the bag

Answer 28

you might wanan add the Banana of grams of water and dye to sound smarterer

Answer 29

dumb science

Answer 30

Actually angel, bag A final mass is 120 grams

Answer 31

whoops typo I meant bag A there, you're right, sorry ^_^

Answer 32

Imma guess the last 3 questions but the other, I need help on

Answer 33

Angel, then wb the last question

Answer 34

How should I draw that?

Answer 35

in pencil?

Answer 36

Yea

Answer 37

if small amount of dye results in some change

then more dye should result in more change

Answer 38

So arrows inward toward the bad?

Answer 39

So like 50% dye and 50% water how will that change the mass

Answer 40

yes

Answer 41

i think

Answer 42

Everything inward?

Answer 43

let me look at the pictures

Answer 44

Ok so I have everything but the problem/Question, hypothesis/prediction, and control

Answer 45

okay the mas of the water will go up with the more dye that is in there

Answer 46

hypothesis is a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation

Answer 47

So how should I write out the hypothesis?

Answer 48

"If I give a plant an unlimited amount of sunlight, then the plant will grow to its largest possible size." example of one

Answer 49

If more the dye is more than the water then the more mass will incress

Answer 50

They want me to write a hypothesis about how the scientists had dont this experiment before

Answer 51

if the dye is more than *

Answer 52

Done*

Answer 53

The scientist used a differant amount of water and dye each time. If the scientist did not do this experiment before they would not know the effect of dye on the water

Answer 54

because he knows the more dye he adds the more mass it will have

Answer 55

But they want me to write that they might have done before

Answer 56

For now what do you think the control is?

Answer 57

the water or dye but im not sure

Answer 58

I think it’s bag A and bag B cus the scientists need them for comparison

Answer 59

Yes correct

Answer 60

Ok now I just need to figure out the 1st 2 questions

Answer 61

send dem

Answer 62

Do you need me to write it?

Answer 63

no i should bec goood

Answer 64

the questio is how does the amount of dye effect the bag mass

Answer 65

the other one is they knew the amount of dye to put in there and the amount of time to put it in there for

Answer 66

Ok I got it
