The answer is a lineage
A phylogenetic tree demonstrates, visually, the relationships between species and their common ancestry to depict evolutionary trend. This tree is based solely on similarities and differences in phylogeny (genetically and phenotypically) of organisms.
Therefore a branch portrays divergence in phylogeny of two species from a common ancestry thus forming two different lineages.
High tide. That is where the tidal bulge is.
Hypothalamus
The hypothalamus maintains a steady internal environment for the body.
The hypothalamus is a complex part of the brain that is located under the thalamus and above the pituitary gland. One of the main roles of the hypothalamus is to maintain homeostasis by keeping the human body in a balanced condition. The hypothalamus plays a part in various important functions of the body such as appetite and weight control, body temperature, emotions, sleep cycles, stress, blood pressure and levels of hormones in the circulation.
