Summary Introduction
A phylogenetic tree is the diagrammatic representation of evolutionary relationships among organisms. The structure of the phylogenetic tree is comparable with the tree which has many branches. The root of the phylogenetic tree is the common ancestor and branches are related genus and species. The most common ancestor lies at each branching point.

- Biology Questionarrow_forward✓ Details Draw a protein that is embedded in a membrane (a transmembrane protein), label the lipid bilayer and the protein. Identify the areas of the lipid bilayer that are hydrophobic and hydrophilic. Draw a membrane with two transporters: a proton pump transporter that uses ATP to generate a proton gradient, and a second transporter that moves glucose by secondary active transport (cartoon-like is ok). It will be important to show protons moving in the correct direction, and that the transporter that is powered by secondary active transport is logically related to the proton pump.arrow_forwarddrawing chemical structure of ATP. please draw in and label whats asked.
