The hemi
metabolism<span> indicates the three distinct
stages of the life cycle of some insects: the egg, nymph, and the adult stage,
or imago. It has no pupal stage just like the complete metamorphosis that
undergoes pupal stage before turning into adult. Insects that undergo hemi metabolous metamorphosis go through gradual changes; develop from
eggs into nymphs sometimes called larvae by some entomologists, that are
similar in shape to the adults. You can
distinguish the nymphs from the adults by looking for wings. Wing buds
or wing pads may be present in late stage nymphs, but they are fixed in place
against the body and are non-functional compared to the adults whose wings are
fully developed. </span>
The Doppler Effect is also known as red shift. Red shift shows the distance of galaxies. The redder the shift then the further away the galaxy, however the bluer the galaxy then the closer it is. Red Shift shows that the universe is continuously expanding. <span />

Secondary succession:<u> follows a disturbance that destroys a community without destroying the soil.</u>
