Cladograms, also sometimes called the phylogenetic trees are diagrams of evolutionary relationships between species.
These diagrams are constructed by biologists based on genetic and anatomical similarities between species.
In the cladogram of vertebrates presented below you can see that the birds and the crocodiles are placed on the same branch (clade) which indicates that they are closely related.
All the statements are true that is Sweating is an example of positive feedback because when you sweat your body becomes hot and your inner body becomes cool. Shivering is an example of negative feedback because shivering occurs when there is cold in the body and can lead to sickness. The nervous system is responsible for sensing changes in the environment because it is responsible for sensing what's going on in our body.
