abb samajh agayee hai iss liyah kah raha hai

samaj ab tak nai ai bas argue kar ke takgya
and also due to our extended argument, this thread cud get locked, which i dont want

we were discussing bio
nothing wrong about that

Do viruses contain DNA?

Do viruses contain DNA?

no they don't
they are non-living, and instead have a nucleic acid inside them

tell that to the mods then

Do we have to know about the names of the plants that a specific vegetation method can be done on?
for example, the book says
' Marcotting can be done on plants such as lime or bougainvillea'
do we have to know that marcotting can be done on lime or bougainvillea

also do we have to know the types of plants that have rhizomes, bulbs, corm, and stem tubers?

Yes, I saw a question in which they asked about how vegetative propagation is done on a named example so you should know that for atleast the most common plants/shrubs like rose etc. Learning that is not very difficult as this is very general like we all know onions have bulbs and sugar cane has rhizomes.

Physics is so hard. :/

Ikr, the MCQs beat the hell outta you. I haven't even touched it as yet, will be starting tomorrow. It is actually very tough.

Chemistry MCQ's are so easy. This is definitely hell. ._.

But these are words of the book, ' The virus is made up of one nucleic acid either DNA or RNA.'

I make stupid mistakes, though and feel like killing myself.

sorry i made a mistake
yes viruses do contain DNA
the DNA or RNA can be double or single stranded

The CIE people make the MCQs so tricky. Did you see the w13 O/N paper 1?

nope not yet but if it is hard then probably our paper will be easy

I did that today, got three MCQs wrong. It was quite technical.

but i found the Chemistry one easy
it also contained some repeated MCQs from i think the 2006 paper

thats the prob with everyone
yeah i saw it
lost 4 marks, 2 really stupid mistakes, and 2 like that
man CIE sure make one hell of a paper, it sure explains the 1 year they take to make the paper
but we will really have to cut down the stupid mistakes occuring
i just wonder about those who got a distinction, dont they make such mistakes

 

[black widow]

I did that today, got three MCQs wrong. It was quite technical.

the others were simple
i found 5 to be very technical
could u tell me about the last MCQ, about the natural selection, how is it C?

 

[Nabeel.Ahmad]

How do i master Biology? .-.

I seriously suck at it. Should i read the whole book once, thoroughly? How long should that take?
