dezzi....do you still need the answers to the Irn Bru and the respiration rate of plants

yes please kathy

The plant respiration one I found this:

Respiration rate indicates metabolic activity in plant tissue. It is also a guide to the potential storage life of fruits. Generally, the higher the respiration rate, the shorter the storage life. Respiration rate is measured by recording carbon dioxide production. Generally, respiration rate is highest at the early growth stage, and declines with fruit maturity (Figure 3). However, plantain and banana are exceptions because of the climacteric response.

However, I think just saying 'plants' means its going to be a very difficult one to get completely right as just this source has come up with 2 exceptions to the rule and I think its just talking about fruits!

And the Irn Bru one, based on water:

The human body can survive a surprisingly long time on water alone, but it is nowhere near six months. When the body is deprived of new fuel (i.e., food), it breaks into its energy reserves to keep going. The body stores energy in the form of carbohydrates, fats, and proteins.
After one day without food, the body will have used up its carbohydrates, which are stored as glycogen in liver and muscle cells. After that, it's on to the fat reserves. Your average Joe/Jane, weight-wise, has enough fat reserves to live for four to six weeks without food. After that, the body begins to use its protein reserves (basically, the body itself). Body proteins are used up at a much faster rate than fat, and you could really only get another two to three weeks out of protein. At that point, however, you can't really call it living since so much irreparable damage has been done to the body, including the brain.
Bottom line: an average person could live for about eight weeks on water alone, give or take about a week for an over- or underweight person, respectively

Obviously this doesn't factor in the sugar content of Irn Bru, but I wouldn't have thought it could make much difference...

Storm

Ooo, and just found this:

As a steady diet, sugar is worse than nothing. Plain water can keep you alive for quite some time. Sugar and water can kill you. Humans [and animals] are "unable to subsist on a diet of sugar".4

If a swimming pool 30ft long 20ft wide and 10 ft deep was fillled with baked beans how many beans would there be?

I thought this but probably wrong....

30 x 20 x 10 = 6000sq ft

1 bean = 1cm

30.48 cm in a foot

6000 x 30.48

182880 beans??
is that right?

No, sorry. It's a 3 D problem!

The pool is 6000 cubic feet (30*20*10). A bean is, say, 1 cubic centimetre.

1 cubic centimetre is 0.061 cubic inches.
6000 cubic feet is 10368000 cubic inches (6000*12*12*12).

so the approximate number of beans is 10368000/0.061 = 169,967,213:D

not including the sauce!

Hi dezzie

I see you already have the answers you need however if it helps someone I know had the same questions and he just got accepted, look like you have the same test paper.

I don't really want to post his answers on here in case it scuppers his chances...not likely I know but just in case.

If you want them PM me with your email addy and I'll send them to you...also if there any others you are struggling with let me know.

Cheers
Kathy
