Explanation:
Animals do not possess any sort of cell wall since animals always move, they are not static in one particular place, therefore they need to be flexible.Animal cells lack the thick cell wall that plant cells have, so there is no need for a central vacuole to exert pressure on the surrounding cell
Answer:
Wingless offspring
Explanation:
Complementation is the terminology used for finding difference in the mutation of same or different gene.
Two groups with same complementation have failed to complement each other.
Thus, two wingless flies will have the same genotype i.e “ww”
When two wingless flies are crossed following offspring are produced
ww * ww
ww, ww, ww, ww
All the offspring are wingless too
