5) find out how many division of the eye piece make up one on the stage micrometerhttp://papers.xtremepapers.com/CIE/...nd AS Level/Biology (9700)/9700_w11_qp_12.pdf

Q16(C), 39(C) HELPP ! Could someone explain?
12) its tertiary for both bcz only the most complex of structure is altered and that too just a bit... the basic structure of the protein remains unchanged. just the shape changes (tertiary structure) so that it does not fit.

first calculate the mass of the given no. of inviduals of a specie and then find their total energy by multiplying the answer with energy value. i.e.
(no. of species)*(mass)*(energy)
the largest value will be for the first trophic level as they have the highest amount of energy. as we move up the food chain the amount of energy for each level starts decreasin...
best approach is to first write the energy values infront of each option respectively and then arange them in descending order in the options.
R = 1000 (just multiply all the three values)can u solve it plz
does tb have a vaccine?
so TB is a viral disease and vaccine is used to combat it??There's the BCG vaccine. Although it's not 100% effective, it's the best we've got so far.
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
