Absolute threshold is the minimum intensity of a physical stimulus that can just be detected by an observer.
Explanation;
An absolute threshold is the smallest level of stimulus that can be detected, usually defined as at least half the time.
-It can be applied to any stimulus that can be detected by the human senses including sound, touch, taste, sight, and smell.

<u>Answer:</u>
Organisms C and D are more closely related than
Organisms A and B
<u>Explanation:</u>
Organisms A and B are not related much as the distance between them is more than the organisms C and D so the C and D are closer than A and B. The phylogenetic tree shows the biological evolutionary relationship among various biological species. So the given tree shows the relationship as mentioned above.
It also show the physical and genetic relationship among the various biological species. The phylogeny is generally shown by using a particular phylogenetic tree. For example, the simple one below which describes the different evolutionary relationships between the great apes. The genus Pongo includes orangutans, Pan includes chimpanzees and bonobos, and Homo includes humans, while Gorilla is self-evident.
