One of the major ways that plants lose water to the environment is by opening their stomatal pores to let CO2 in for photosynthesis, which also results in water loss. The higher the concentration of CO2, the less often a plant has to open its pores to let in CO2. If the growth of a plant is water-limited and we experimentally increase the concentration of CO2 near the plant, what would we predict would happen to the plant’s growth rate?

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.
