Wasn't the difference in the area of the zone disinfected?

I worked out the area of a circle for each and worked out how many times it was greater by dividing the area of the circle values.

gg 0 marks looool

What did you guys write about the question why the scientists drew the conclusion, it was about HIV and natural selection.

I was thinking natural selection takes place over a long period of time and HIV was recently discovered. I also put natural selection gets rid of non-beneficial genes for more favourable/desirable ones

Ugh I didn't think about calculating the area - I just did the diameter of D divided by the diameter of B.

I didn't like that paper, it started off well but just got worse. Am I the only one who thinks it?

soo true although i liked the starch and cellulose at the end but then translocation hit me and i was like why

Don't worry, more than likely I've done it wrong. I am really **** at Biology

Why did the sample need to be thin?

i think so light could more easily pass through and it could b seen clearly

I crammed the translocation thing this morning as well :lol:

:lol:

Was so happy when it came up.

How many marks was the question about what cause the clear zone and also the question about why above 40% shouldn't be used?

i basically said that their offspring may not have the mutation and that people rarely come in contact with hiv disease and so few die from ir

hopefully like 60% for an A :frown:

:frown:

probably not though :frown:

:frown:

What questions/topics came up in todays paper?

kill meeeeee

How many marks was the question about FEV, precautions that should be taken?

What was the answer to the non smoker FEV reducing? I put something silly like the alveoli cells not being able to regenerate

kill meeeeee

that was a complete guess tho aha

What did people put for the mutation question and how it leads to a non functional protein.

i described the types of mutation so deletion and substitution and told about how they work

For the ratio I did 25/5 and got 5:1
for the clear zone I calculated area of circle divide by each and got like 2.5x bigger
