Question about temp senser instead of thermoneter was its more accurate right ?


Posted from TSR Mobile


I put that it detected changes instead of displaying a constant current temperature. didn't really know that a temperature sensor was tbh
What did you all get for the mosquito question?
(Correct me if I'm wrong but that question so weird! I don't think that was even in the specifications.)

It was 0.6% recurring.

I remember the question.

It was 3*10^8 people get malaria and 2*10^6 died from it.

To work out a percentage you take the lower number and divide it by the higher number and then * by 100.

There you get

(2/3 * 10^6/10^8) * 100

2/3 * 10^6/10^8 is 2/3 * 10^-2.

This is 0.006 recurring.

However then you times by 100 since it is a percentage.

This leaves you with 0.6% recurring of people dying.

I did ALL of this and then changed it to 66% because I thought it was too small an answer :frown:!!
the colour of the snail I commented on light levels. For the Gm mosquito for marker I think the advantage was that they don't feed on humans therefore wont spread disease. Disadvantages: unknown side effects in years to come, may effect food chains.

It was a scatter graph about snails, maybe there wasn't a question about the graph except why use a scatter graph or something like that?

The graph with woodland and grassland snails


Oh right, that one. Thanks!

I've forgotten what I put down anyway, but I'm sure it was wrong.
Why was a scatter Graph used? Question on last page

Yeah, I'm pretty sure it said organism, and that does seem more like AQAs style to say organism, however it may have been animal, but I doubt it.


No, it definitely said animal
