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).

Answer:
Rotifers are specialists at living in habitats where water dries up regularly.
The Monogononta, which have males, produce fertilised 'resting eggs' which can resist desiccation (drought) for long periods.[11]
The Bdelloids, who have no males, contract into an inert form and lose almost all body water, a process known as cryptobiosis. Bdelloids can also survive the dry state for long periods: the longest well-documented dormancy is nine years. After they have dried, they may be revived by adding water. In this, and several other ways, they are a unique group of animals.[12]
Explanation:
The front has a ring of cilia circling the mouth. This gave the rotifers their old name of "wheel animalules". There is a protective lorica round its body, and a foot. Inside the lorica are the usual organs in miniturised form: a brain, an eye-spot, jaws, stomach, kidneys, urinary bladder.
Rotifers have a number of unusual features. Biologists suppose that these peculiarities are adaptations to their small size and the transient (fast changing) nature of its habitats.
Answer:
Chlorophylls are natural green pigments ubiquitously present in plant kingdom, which play an important role in photosynthetic process, a vital function for life on Earth.
