This rapid change in species that rarely leaves behind fossil evidence is referred to as a) natural selection. b) adaptive radiation c) directional selection. d) punctuated equilibrium.

from the original order (top to bottom) the new order will go

1 (founder)

4 (hawk)

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
