The enzyme is- a Inolase b Hexokinase c Lipase d Taq-Polymerase 3 Lower groups of animals have -------- but lack -----------. a Exoskeleton, Endoskeleton b cytoskeleton, exoskeleton c Endoskeleton, Exoskeleton d Endoskeleton, cytoskeleton 4 A zoology student studying mollusks found that some snails are hermaphrodites and they reproduce both by self and cross-fertilization. They have a gene of coiling pattern of shells on their back. The shell coils it either in left handed or right handed manner. The allele of right- handed coiling is dominant over left-handed coiling.
