Using the weeks before the exam

Take the free check first: it shows which of the eight sections costs you most marks. Then work section by section with its lessons and practice, and sit a timed Section 1 paper every week or two.

Try 2 questions

Question 1Section 1 style
In a cell, all of the coenzyme NAD has been converted to NADH, and none is converted back. Which stages of respiration stop because their dehydrogenase enzymes can no longer work?
Question 2Section 1 style
A table of four woodland fragments. F1: area 50 hectares, 0.5 km from the nearest fragment, 42 bird species. F2: 50 hectares, 4 km, 29 species. F3: 10 hectares, 0.5 km, 25 species. F4: 10 hectares, 4 km, 16 species.
FragmentArea (hectares)Distance to nearest fragment (km)Number of bird species
F1500.542
F250429
F3100.525
F410416
The table shows the area of four woodland fragments, their distance from the nearest other fragment, and the number of bird species found in each. Which conclusion do the data support?
