Answer: The correct answer is- gymnosperms and angiosperms.
Phylogenetic tree is a diagrammatic representation that depicts the evolutionary relationship among different group of species. In other words, it is used to interpret the relatedness among different species and how they have descended from a common ancestor.
The tips in the phylogenetic tree represents the taxon ( or particular group of species) that are descended.
In the given tree, gymnosperms and angiosperms have evolved most recently because they correspond to the most recent branches having the immediate common ancestor at the topmost level as compared to the immediate common ancestor of other taxon.
Thus, gymnosperms and angiosperms is the right answer.
Our central nervous system is made up of two tissues: the gray matter and the white matter. The gray matter is composed of the dendrites and the axon terminals where synapses are. These synapses are the links between neurons that transmits electrochemical signals. The white matter, on the other hand, is composed of axons that connect all the gray matter together. Therefore, the answer is: <span>white matter is primarily in the CNS in the presence of myelinated axons</span>
The statement 'symbiosis is a relationship between organisms in which both benefit' is TRUE about this they of ecological interaction.
