Answer: The correct answer is -
D. Eukarya has similar evolutionary traits to archaea.
A phylogenetic tree (also known as evolutionary tree) is a diagrammatic representation (in the form of branch diagram) showing the evolutionary relationships among various organisms. It is constructed on the basis of similarities or differences in the genetic or physical characteristics of various species.
In the given phylogenetic tree, archaea domain shows more similarities to the domain eukarya as it has descended after the domain bacteria.
Thus, option D) is the right answer.
Adenosine regulates synaptic activity through its actions on presynaptic autoreceptors. Adenosine A1 receptors are expressed at a presynaptic locus withinside the BLA and that activation those receptors substantially inhibits glutamate launch possibility onto BLA pyramidal neurons.
The adenosine A2A receptor is a G-protein-coupled receptor that may be a most important goal of caffeine and vital for regulating myocardial oxygen consumption, coronary blood flow, and CNS neurotransmitters, hence a receptor of hobby for brand new drug development.
The adenosine A2A receptor is particularly gift with inside the brain, heart, lungs, and spleen. The adenosine A2B receptor has its most important distribution with inside the big gut and bladder, and the adenosine A3 receptor is gift inside the lungs, liver, brain, testis, and heart.
