(2ai)
G = Maize fruit
H = Mango fruit
I = Tomato fruit
J = Cockroach
K = Earthworm

(2aii)
H= Drupe
I = Berry

(2aiii)
Similarities

* Both have Endocarp for protection of seed
* Both have Mesocarp for storage of seed
* Both have seed

(2aiv)

Difference btw H&I
* H = it belong to drupe WHILE I = belong to berry
* H = It has hard and strong Endo carp WHILE I = Has soft and fleshy Endocarp

(2bi)
(1) Animal
(2) Wind


(2bii). Difference Btw J&K

J = belong to Insector
K= belong to ammelia
J = possess of wings

K = absence of wings
J = it lives in dark corners
K = lives in moist soil
J = it under goes incomplete metamorphosis
K = Does not undergo metamorphosis
J = It destroy household materials
K = It serve as decomposer

(2biii) [ Specimen J ]
* It transmit diseases
* it destroy household materials
* it decays organic matter [ Specimen K ]
* it loosens the soil
* it aerate the soil
* it decomposes plants and animals matters
