you are using proteins to synthesize proteins??? lmao!!

it was hormones typing mistake..

 

[areeba fatima]

If they tell to plot a graph, should it be a straight line or a curve?

it would be clear in the question to draw a straight line...line of best fit or a curv

How can we say like this.. it depends on ques

 

[Spidey21]

yeah you use protiens to form hormones and cell growth both!!

 

[xxvvyy]

no i mean check 2005 m/j paper there they say to draw a graph ?

 

[Spidey21]

If they tell to plot a graph, should it be a straight line or a curve?

it totally depends on the relationship between the two things given
!!

 

[xxvvyy]

so should it be a best line fit?

 

[MustafaMotani]

One thing everyone is not aware of :
If something(e.g.extension) is directly proportional to another thing(force) then their graph will always pass through origin.
Graph is straight line wid positive gradient
If something (volume) is inversely proportional to something (pressure) then their graph will never intersect xaxis and y axis.
graph is downward slope

Any graph wid straight line having positive gradient but not passing through origin can be said that two variables have direct relation but not directly proportional
Any graph vid downward sloping intersecting any axis can be said that variables have inverse relation but no inversely proporional

that I know but it was mcq and these both were options.. :S

 

[ashiqbal]

u kidding It surely helps ..
where did u get that pic from anyway.. ??

i made it (the editing part, the table and block were in past papers)

 

[ashiqbal]

so what was the answer? i chose cell growth, as they asked for ESSENTIAL use of protein!

gr8..

exactly but its matter of fact that widout hormones cell growth is not possiBle at least proper cell groeht

 

[ashiqbal]

exactly but its matter of fact that widout hormones cell growth is not possiBle at least proper cell groeht

i dont think that is necessary! i dont think that hormones control cell growth, that is dependant upon DNA! anyway, forget that 1 mark, now prepare for physics!

That's right

nice but examiner report says use newton meter preferably how do we do that????

u said it urself that without hormones NORMAL CELL GROWTH will not take place. but wat if there is NO CEL GROWTH phir kia hormones ko sar mein marna hai :LOL lolx iss liye i think it was cell growth one. i hope i'm ryt!!

make a slight modification in the pic and hand a HANGER on the string. it is given in the material list. then hang a newton meter on the hanger and from the hook of the Newtn meter hang the load

I would say use newton meter with two side hooks
tie pulley to one and add weights to other..

sorry its the other way round.... tie the N.M. with the string. then hook up the hanger in the NM. place the weight in the hanger
