Answer: When your hypothalamus senses that you're too hot, it sends signals to your sweat glands to make you sweat and cool you off. When the hypothalamus senses that you're too cold, it sends signals to your muscles that make your shiver and create warmth. This is called maintaining homeostasis.
From the diagram above, I dont think that organisms of the same order share a stronger evolutionary relationship than organisms in the same phylum. This is because, after kingdoms, the subsequent categories of increasing specificity are: phylum, class, order, family, genus, and species.
<h3>Levels in taxonomic classification</h3>
At each sublevel in the taxonomic classification system, organisms become more similar.
Organisms that share similar physical features and genetic sequences tend to be more closely related than those that do not.
Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and connections among living organisms.
<h3>Phylogenetic tree</h3>
A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms
<h3>
Taxonomical classification</h3>
Taxonomy is the scientific study of naming, defining and classifying groups of living organisms based on shared characteristics. There are seven main taxonomic ranks:
- kingdom
- phylum ( in animals )or division ( in plants )
- class
- order
- family
- genus
- species.
