Biology P51

[Senorita.K]

its been 24 hours now so i think we can discuss the paper

 

[malk mohamed]

very difficult

 

[alexkay]

Is this the paper with the pre-natal exposure to alcohol in babies and the enzyme subtilis A/contact lense experiment?

 

[muhammad05]

I freakin loved it. Best paper 5 ive ever done. Question 1 was just like paper 3 (Lab)
Question was general knowledge.
Lets hope p4 goes this well.

 

[saraq12]

HOw did you calculate the rate of the reaction?

 

[saraq12]

yes

Is this the paper with the pre-natal exposure to alcohol in babies and the enzyme subtilis A/contact lense experiment?

Wait what?

wasnt this the paper with the pre-natal exposure to alcohol in babies and the enzyme subtilis A/contact lense experiment?

Yes but the first question effectively asked how to calculate rate of reaction (rate of substrate disappearing/ colour disappearing or sheet becoming transparent) to get the actual (optimum) concentration needed for the reaction.

How was the stopwatch question?

 

[muhammad05]

which rate of reaction?

If it was based on the graph, I said that you would have to trace the line of the time taken (horizontal line) to the point on the graph, and read it cosponsoring concentration.

like if time taken was 52 min, then you draw a line to the graph, and read the time tat corresponds.

I said that too, or something similar

STOPWATCH i don't remember seeing this
what was that

 

[Komail Sabba']

what were the suggestions for some of the results not being valid in q2 e?
(prenatal alcohol exposure group)?

i think i wrote about different gender of babies and not equal number of male and female babies were taken
idk if this is correct or not
what did you write?

what did you write?

same. and i also wrote that some mothers may have drank more than others.
stupid point, but idk...

 

[Senorita.K]

what were the dependent and indpendent variables for the first question?

 

[Senorita.K]

what was the independent variable in the second question?

 

[Komail Sabba']

what was the independent variable in the second question?

exposure to alcohol?
