How do nerve cells form different types of tissues? a. a group of these cells perform similar functions and become nerve tissue after messages from the brain tell nerve cells how to develop and perform special functions. b. a group of these tissues perform similar functions and become nerve organs after messages from the heart tell nerve cells to develop and perform special functions. c. a group of these cells perform similar functions and become nerve tissue after information in the dna of the nucleus tells the nerve cells to develop and perform special functions.

The construction of phylogenetic trees is a mapping out the proposed divisions and common ancestors of all living species. traditionally, these trees have been built using morphological data, such as appearance and embryology. recently, it has been possible to construct these trees using molecular data. phylogenetic trees based on different types of information agree with each: that there is strong evidence of a real underlying common descent. this phylogenic tree is composed based on molecular data (rrna). what statements can we infer are true about the organisms throughout the tree? because the tree is rooted, all branches share a common ancestor. all organisms have some sort of cellular structure/organization. all eukaryotes evolved from bacteria. since the organisms contain rna, they share the same dna. if the organisms contain rna, the share the same four nitrogen bases.
