ANS: Specimen A: garden egg: Features:
i) epicarp is soft and flesh
ii) many seeds are present
iii) epicarp is edible
iv) it is dispersed by ant.
ECONOMIC USEFULNESS:
i) used in Control of blindness
ii) good for ulcer patiets
iii) helps to Control obesity. The type of placentation is axile. The botanical name is [solanum
melonge]
Specimen B: Tridax fruits: the botanical name is procumbenis and the family name is calyx. It is a true fruit. It develop from a Superior ovary and have one seed.

absent
2) rostrum present-rostrum absent
3) bristle absent present.
Similarities btw weevil and tick.
1) both have head-thorax and abdomen. Both have jointed legs.
Specimen J: tilapia fish-bony fish. Phylum-chlordata. Sub-phylum-vertebra. Class-pisces. Habitat-aquatic.
Adaptation of fish to its
environments.
Streamilimed body: this allows for easy movement in water.
Gills: offer an efficient means of
respiration in water.
Scales: they protect againt injury, control movement of salt in and out of fish body
Specimen K:- toad. Phylum-
chordata. Class-amphibia. Habitat- live both on land and aquatic habitat. External features the body is divided into head and thrunk.
Adaptation of the toad of life. On land: presence of hind limb for hopping. On water web on the hind limb for swimming over
streamlined shaped for easy movement Absence of neck to reduce friction during swimming.
