does anyone have the textbook BIOLOGY by Campbell 7th edition?
if so, do you think you would be able to do me a favour and maybe desbribe or scan some figures from the textbook for me..i can never get it from the library..theres only one text on reserve for 3 hours and there are hundreds of us
the figures would be from chapter 32, figures 32.2,32.4,32.10 and 32.11
I don't think you use campbell since it is a high-school book(only 1300 pages, anyone can learn it )
I have it but it is only 3rd edition. And i can't exactly photoshop the pictures for you...
"As a biologist, I firmly believe that when you're dead, you're dead. Except for what you live behind in history. That's the only afterlife" - J. Craig Venter
use dictionary for definitions....
first figure 32.2 represents an early embryonic development in animals
zygote->mitotic divisions->blastula(form like hollow ball)->gastrula(result of gastrulation-inward folding)
figure 32.4 represents hypothesis for the origin of animals from a flagellated protist
colonial protist->hollow sphere of unspecialized cells->beginning of cell specialization(somatic&reproductive cells)->infolding ->Gastrula-like protoanimal-can see digestive cavity.
Figure 32.10 Hypothesis of animal phylogeny
(based on development and morphology)
Ancestral colonial flagellate->metazoa->(Porifera,eumetazoa)...Eumetazoa (Cnidaria,Ctenophora-those 2 cause of radial symmetry are called 1.Radiata...and
2.Bilateria-Protostomia(Platyhelminthes,Mollusca,Annelida and Arthropoda,Rotifera,Nemertea<Nematoda) and Deuterostomia (Phoronida,Ectoprocta,Brachiopoda,Echinodermata,Chordata)
Figure 32.11 again hypothesis of animal phylogeny but based on molecular data
Ancestral colonial flagellate->Metazoa(Porifera-Calcarea&Silicarea)->Eumetazoa(1.Radiata-Ctenophora&Cnidaria....2. Bilateria)
Bilateria(1.Deuterostomia-Echinodermata&Chordata...2.Lophotrochozoa-Brachiopoda,Phoronida,Ectoprocta,Platyhelminthes,Nemertea,Mollusca,Annelida...3.Ecdysozoa-Nematoda&Arthropoda....Rotifera separated from previous)
This was just a description...use dictionary and search the internet for pictures

I use it... for a general biology lesson..and yup, this is the result, still lack of bio...
But for the biochem, I use Harper's Biochemistry by Robert K.Murray , Victor R. Rodwell, and friends..
Q: Why are chemists great for solving problems?
A: They have all the solutions.
Well you can relax, Campbell is the book you need to know for IBO. So it is not that general
I actually have the 6th edition Campbell (and the accompanying image bank on CD-ROM). I attached the figures by number, but they may not be the exact ones since there is a edition difference. Let me know.
