Recent work in classification of life on Earth has shown that what were once called prokaryotes are much more diverse than ev
suspected. The prokaryotae are now divided into two domains, the Eubacteria and the Archaeabacteria, as different from each
other as either is from the Eukaryota. One organism, the blue-green algae or cyanobacteria, has left a fossil record that dates ba
nearly 3.5 billion years and is among the oldest fossils known. A few hundred years ago, this organism was classified as a plant
then more recently as a protist. Today it is classified in the kingdom Eubacteria. Which of these would NOT be evidence that
scientists compiled to place cyanobacteria in the Eubacteria.
A- presence of cell walls containing peptidolycans
B- presence of chloroplast for photosynthesis
C- contains a nucleoid rather than a nucleus
D- Forms in outer capsule with slime coat

Chinese privet is a plant that is native to china. over 150 years ago, chinese privet was introduced to the united states as a fast-growing shrub that serves as an excellent privacy hedge. with no natural herbivore, chinese privet quickly established itself and spread in natural areas throughout the southeast and eastern seaboard of the united states. its dominance in these areas has jeopardized the survival of native plant species. chinese privet provides evidence that introducing non-native organisms can cause environmental damage integrated pest management strategies will not decrease chinese privet populations american gardeners can easily control the spread of chinese privet non-native plant species have type i survivorship curves
