a bilateral symmetrical adult animal that has ecto, meso and endoderm derived tissues along with a notochord belongs to which phylum or subphylum?
Answers
Vertebrata: Subphylum of Chordata. Chordata is the final animal phylum. All of its members, known as chordates, have a head, a body cavity, and a digestive system.
Are notochords present in chordates?The notochord is the distinguishing feature of the chordates and plays crucial roles in the development of vertebrates. It acts as a major skeletal component of the growing embryo as well as a source of midline signals that design neighboring tissues.
What kinds of creatures have bilateral symmetry?The great majority of animals, including insects, fish, amphibians, reptiles, birds, mammals, and the majority of crustaceans, have bilateral symmetry.

The phylum Chordata or subphylum vertebrata is made up of bilaterally symmetrical adult animals with ecto, meso, and endoderm derived tissues and a notochord.
what are chordates?
The phylum Chordata and the kingdom Animalia both have vertebrates as members. The four distinguishing characteristics of animals in the phylum Chordata are a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a postanal tail. These characteristics all arise at some point throughout animal development. Some of these are only present during embryonic development in certain groups.
Additionally, chordates have a segmented body, triploblastic, bilaterally symmetrical, and coelomic skeleton.
The body design is intricate and distinctive.
Organ systems are the level of organization found in the body.
The notochord, a flexible, rod-shaped structure present in all chordate embryos and in the adult stages of some chordate species, is the source of the name "Chordate," which refers to a group of organisms. It supports the skeleton along the entire length of the body and is situated between the digestive tract and the spinal cord.
The class Vertebrata includes all vertebrates. Vertebrates have all four of the chordates' defining qualities, but they also have derived traits that set them apart from invertebrate chordates. Vertebrata gets its name from the vertebral column, which is made up of distinct bones called vertebrae that are linked together to form the backbone. The notochord, which is only present in the embryonic stage, is replaced by the vertebral column in adult vertebrates.

A population is a group of individuals from the same species who live and interact in the same area.
A population's health and behaviour are determined by how individuals interact with one another and with their surroundings. The community is made up of many such populations that interact with one another.
The ecosystem is made up of the biotic community and the abiotic environment.

you find an animal with a bilateral larval form but what appears to be a radial adult form. which taxa would you presume it to belong to?
Answers
The animal would be presumed to belong to Cnidaria if they have a bilateral larval form and radial adult form.
In the Cnidaria larvae, bilateral symmetry is a characteristic feature. In the field of biology, bilateral symmetry can be described as a type of symmetry in which when an organism is cut into half, both the right and the left side appear to be exactly similar.
However, after growth from the larval stage, the Cnidaria adults develop to have radial symmetry. In the field of biology, radial symmetry can be described as a type of symmetry in which the body has a central axis where all the lines or planes of the body of the organism can unite.

The common function of leaves are: water storage, energy transportation water transportation and energy synthesis.
Describe the function of leaves.The main function of leaves is to produce food for plants through photosynthesis. Chlorophyll, the substance that gives plants their unique green color, absorbs light energy. The internal structure of the leaf is protected by the stem epidermis and the continuous leaf epidermis. The central sheet or mesophyll is composed of soft-walled, unspecialized cells of a type known as the parenchyma. Up to one-fifth of the mesophyll consists of chlorophyll-containing chloroplasts that absorb sunlight and, in combination with specific enzymes, use radiant energy to break down water into its elements hydrogen and oxygen. . Oxygen released by green leaves replaces oxygen removed from the atmosphere by respiration and combustion of plants and animals. Hydrogen obtained from water combines with carbon dioxide in the enzymatic process of photosynthesis to form sugars that form the basis of plant and animal life. Oxygen is released into the atmosphere through stomata (stomata on the leaf surface).
