In order to be classified as a green plant, an organism should be eukaryotic, have double-membraned chloroplasts, cell walls, and go through the process of . Land plants likely evolved from . Plants have a life cycle that is called the alternation of generations. The two phases of this life cycle are the diploid stage and the stage. A plant structure that contains a full set of paired chromosomes is called a . There are two key transport tissues in plants. transports water from the roots to the rest of the plant, while phloem transports sugar and nutrients.

Charles darwin published his theory of evolution in 1859. in what way foes modern evolutionary theory differ from the theory as proposed by darwin? a) darwin inferred that individuals can evolve, but modern generic science has shown that this is not true. b)darwin inferred that individuals do not evolve, but modern genetic science has shown that this is not true. c)modern science has disproved most of darwin's original theory of evolution, because darwin knew nothing about generations and their role in heredity. d)generic studies have shown that gene expression and other factors operate along with natural selection, but most of darwin's theory has been supported by modern science.

Recent research by marine biologists suggests that bottlenose dolphins have names for themselves. scientists played sounds they had identified as the names of particular dolphins, putting them through a synthesizer so that they did not sound like the voices of particular dolphins. the researchers found that dolphins would respond to the names of other dolphins that they were related to or associated with, but they ignored the names of strangers. this discovery suggests a much greater degree of self-awareness in aquatic mammals than was previously suspected. if this research holds up, what does it suggest about dolphins?
