NABTEB. PRACTICAL BIOLOGY ANSWERS
2a)
Specimens:
A-Cowpea plant
B-Maize plant
2b)
A-Reticulate veination
B-Parallel veination
2c)
A-Epigeal germination
B-Hypogeal germination
2d)
Specimen A contains root nodules.Inside these are found bacteria.These bacteria help to fix atmospheric nitrogen to the soil.When rainfall fixed
nitrogen dissolve in it to form nitrate which is good to the crop
2e)
A-protein
B-Carbonhydrate
2f)
-Leaves of A is oval in shape while that of B is parallel
-Leaf of A has reticulate veinations while that of B has parallel veination
-Leaf of A is not hairy while leaf of B is hairy
-Carbium is present in leaf of A while it is not in B
3a)
Specimen C-Scapular bone
3b)
Shoulder
3c)
Anchors and attaches muscles which work the arm
3d)
-Hair/fur cover the body
-There is a pair of pinnae
-There is a pair of eyes with eyelids
-Body is divided into head,neck and trunk with tail

5bi)
Zooplankton->Tilapia->crayfish->kingfisher
5bii)
Producer->Zooplankton
Tertiary consumer->Kingfisher
1)
i)Essential for chlorophyll formation
ii)Nucleus
iii)ATP(Adenosinetriphosphate)
iv)It helps the gases to diffuse in and out of the plant
