viruses and plasmids.
Describe a social, economic and ethical reason for/against GM

[Jamsebob]

chemical energy is what is formed from the light energy when a plant photosynthesises and is passed onto the next trophic level. Basically what energy in food is.
At least that what it is at the best of my knowledge.
All the mark schemes just state "correct use of the term chemical energy"

Social - GM crops could cause allergies or transplanted genes may get into the environment.

Moral - Some say it is unnatural and therefore unethical to genetically modify genes

Economic - Farmers get more yield from GM crops, making it cheaper to produce.

Ikr - the best answer i got in the mark scheme was that it comes from the Sun lol. So its not light energy, its whats formed in photosynthesis?

Oh yeah i forgot the question.

This hasn't come up, so:

What is RICE? And name four common injuries that comes from excessive exercise.

[swaine.]

Rest - to avoid further damage
Ice - to reduce swelling (by reducing temp. & blood flow)
Compression - e.g.a firm bandage - to reduce swelling and prevent further damage
Elevation - reduce swelling; makes it easier for blood to flow back to the heart

And...
1) sprain
2)torn tendon
3)torn ligament
4)dislocations

The rate at which photosynthesis takes place can be measured.
One way to do this is to count the bubbles of oxygen given off by a water plant in one minute.
Explain why trying to count the number of bubbles in one minute in this experiment may not give the true value for the rate of photosynthesis:

Chemical energy is the part of energy in a substance which can be released by a chemical reaction

Thank you for the answer, I got the same one from google definitions but it just confused me - James explained it though.

Anyway, one minute may not be long enough, some oxygen may be used for respiration, there may errors in counting. (I didn't copy i swear

What is the compensation point of respiration and photosynthesis?

Good luck tomorrow everyone

Good luck to you too..gonna have a long night though because i have history too

How did everyone think it went?

Got confused on the economic/ social/ ethical one!

same, i put anita, jane then julie but people were saying it was peter last

[bookworm786]

I thought it was really good! Almost every question had been on a past paper.

[Jamsebob]

I thought it was really easy had practically memorised the mark schemes for all the past test papers and the questions were pretty much copied.
Though i thought the social and ethical answers were a bit confusing/ambiguous. Apart from that though it was easy-also our teacher practically gave us all the ideas questions in our lesson before so they were easy!

So what did you put for the social, ethical and economical? I don't know why everyone was saying that particular question was so hard.

[Jamsebob]

unfortunately can't remember perfectly but I think I put the one about affecting other crops as ethical (which now I come to think of it could be wrong) Maybe if you could list the other two(excluding the obvious economic one and the one that plainly related to nothing(the top right one I think)) then I might be able to tell you.

omg the atp bit i did awful in. what did you label structure A as in the heart diagram?

Valve, and then for the next part veins. Now i know its bicuspid valve, so i'm not sure if i'd get the mark. Oh well
