Our blood is mostly water. blood has the important job of circulating nutrients and ions to every cell in our body. the only reason blood is able to do this is because it is mostly water, and water is very basic it is mostly water, and the bonds of water are not able to be broken it is mostly water, and water is a universal solvent dissolving many different substances it is mostly water, and water is a non-polar liquid

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.

How many trophic levels are there in the following food chain? phytoplankton - shrimp - perch - pike - osprey

The study of interaction between living organisms and their enviroment is called (a) phytogeography (b) ecology (c) phytosociology (d) ecosystem
