The process of classifying an organism into a clade by comparing similarities in body symmetry and other morphological traits comprises - 1. body plan-based cladistics cladistics based on body plan, morphology-based phylogeny.
<h3>What is cladistics based on body plan ?</h3>
A method of biological taxonomy that organizes taxa in a branching hierarchy so that all members of a given taxon share the same ancestors and defines taxa uniquely by shared traits not present in ancestral groupings.
- Cladistics is a method of biological classification in which groups of species (or "clades") are assigned based on theories of most recent shared ancestry.
- The evolutionary link between recent ancestors and descendants, or the course of evolution, is shown via cladistics. An aid to representing it is a cladogram. Since clades serve as the foundation for phylogenetic trees, cladistics is a component of the phylogeny.
<h3>What is molecular-based phylogeny ?</h3>
Molecule structure is used in molecular phylogeny to shed light on an organism's evolutionary connections.
- A so-called phylogenetic tree represents the findings of a molecular phylogenetic research. DNA, RNA, and proteins are components of all living things.
- Molecular phylogenetics creates a phylogenetic tree by drawing conclusions about the evolutionary links that derive from molecular evolution.
<h3>What is Morphology-based phylogeny ?</h3>
Using anatomical features, morphological phylogenetics infers evolutionary trees. Node: A branching point when an ancestral lineage splits into two (or more) daughter lineages in an evolutionary tree.
The ability to discuss the phylogeny of fossil taxa and how they relate to modern taxa is the unquestionable benefit of morphological data. However, their strategy prevents us from addressing the situation of extinct taxa for which there is no way to gather DNA data (i.e., almost all of them).

Interneuron, skeletal muscle, somatic receptor, afferent nerve fiber, and efferent nerve fiber.
The action potential from skin receptors is sent by nerves in this type of reflex system.
Sensory neurons advance the motion to the Central Nervous System (CNS).
The efferent neuron or motor neuron causes changes at the effector, which are the skeletal muscles, for adequate integration and responsiveness.
Reflex action refers to the full series of actions. The reflex arc is the name of the route.
Somatic receptor followed by afferent nerve fiber, interneurons, efferent nerve fiber, and skeletal muscle constitutes the proper order.

mRNA (Messenger RNA) is translated by ribosomes and contains the code that specifies the sequence of amino acids in polypeptide chain.
A single-stranded ribonucleic acid molecule is known as messenger RNA(mRNA) plays a major role in <u>translation</u>.
Translation is the method by which an mRNA codes for a certain protein. mRNA provides the template for<u> protein synthesis</u>.
The ribosome translates the mRNA that is produced from the DNA into a chain of certain amino acids and<u> protein synthesis</u> is facilitated by this <u>amino acid</u> sequence.
<u>The genetic code</u>, which connects the DNA sequence to the amino acid sequence of proteins, is used to "read" the mRNA. Each group of three nucleotides in mRNA forms a codon, and each codon corresponds to a particular amino acid (triplet code).
Thus mRNA contains the code that specifies the<u> sequence of amino acids</u> in a polypeptide chain.

Answer:
Dopamine.
Explanation:
Cocaine is used as a recreational drug and addictive in nature. It can be smelled or directly inhaled in the veins. This drug causes the feeling of restless and happiness.
The dopamine is the important neurotransmitters that regulates the mood and other biological activity of the body. The cocaine inhibit the reuptake of dopamine and leads to its accumulation in the brain. This might also break the blood brain barrier.
Thus, the answer is dopamine.
