There are different characteristics for differentiating the members of different phyla in kingdom animalia.
The phylum is the level of organization just below the kingdom. In Animalia there are nine major phyla.
The first is porifera and it has a cellular level of organization. It is acoelomate and does not have symmetry.
After that the Coelenterata has tissue level of organization, radial symmetry and no coelom. They are essentially sessile, and have polyp or medusa body forms.
Ctenophora called comb jellies are radially symmetrical with tissue level of organization, no coelom and have external plates of ciliated plates called comb plates.
Bilateral symmetry is observed from platyhelminthes, they lack coelom and from this phyla organ & organ system level of organization is observed. Aschelminthes are pseudocoelomates and have a false coelom. From annelida onwards coelom is present. Annelids have segmentations (internal and external and are called roundworms. Arthropods have jointed legs and outer exoskeleton of cuticle. Molluscs have a visceral hump and a muscular foot and often an exoskeleton of calcium and radula for feeding.
Echinodermates has radial symmetry and a water vascular system for locomotion, feeding, movement etc.
Hemichordates are worm-like with, proboscis collar and a trunk.
Cordata members have a notochord and a dorsal hollow nerve cord. And may have gill slits with limbs or fins
Based on the stages of development and the characteristics present the phyla of the animalia are described. Traits like level of organization, body symmetry, the development of the notochord etc are used for the classification.
Thus the traits of major phyla are described above.

Which is the end result of cytokinesis?
Answer:
The end result of cytokinesis is one cell physically divides into two cells.
Explanation:
The process of the M- phase of cell division, by which 1 cell divides into 2 cells is the cytokinesis. Cytokinesis takes place after the karyokinesis. It normally follows nuclear doubling. It occurs in both mitosis or in meiosis.
Plant cell cytokinesis is different from the animal cytokinesis because of cell wall rigidity. Plant cells forming cleavage furrow, cell plate arises a double cell wall for both daughter cells. Cytokinesis is the final stage of the cell division or cell cycle.
Thus, the end result of cytokinesis is one cell physically divides into two cells.

Vestibular senses, kinesthetic sense, and skins senses all make up:
The correct answer is Vestibular senses, kinesthetic sense, and skins senses all make up: Somesthetic senses
Somesthetic senses are the sensation that is produced by the skin, joint, muscles, viscera and organs of balance. Merely looking at the word, the first part “soma” means body, esthetic, which is the second part, means feelings.
Further ExplanationWe have three somesthetic sense system, they are the skin senses, the kinesthetic sense, and the vestibular senses
The skin senses: It plays the role of receiving and transmitting information from the outside into the central nervous system. The sensory receptors collect information about pressure, temperature, including pain. Simply put, the skin senses is the sensory systems used for processing touch, cold, pressure and pain.
The kinesthetic senses: when your eyes are closed with your hand raised above your head, you surely know where hand is because there are receptors known as proprioceptors, which is responsible for telling you about joint movement or contracting. These special receptors are part of the body senses movement and tell you where your arms, hand, leg are located in relation to each other. This senses is known as kinesthetic senses. It is the senses of posture, muscle movement and strains on joint and muscle.
The vestibular sense simply refers to the sense of balance. This senses structure is present within the innermost chamber of the ear. Vestibular sense are structures in the air that tells you about the body position. Simply put, it refers to the senses of balance, acceleration and position in space.

Animals that have their body parts arranged around a central point are A. spherically symmetrical. B. bilaterally symmetrical. C. radially symmetrical. D. asymmetrical.
Animals with body parts arranged around a central point are radially symmetrical. This structure is common in species like starfish and jellies, where any slice through the central axis produces mirrored halves.
Explanation:Animals that have their body parts arranged around a central point are C. radially symmetrical. This form of symmetry is common in several species, particularly those from the cnidaria and echinoderm group, which includes jellies and starfish, respectively. In radially symmetrical animals, any slice passing through the central axis will divide the organism into mirrored halves. Unlike bilateral symmetry (seen in humans, for instance), where only one plane can divide an organism into two virtually identical halves, radial symmetry allows for multiple planes of division.

Analyze and conclude 7. which, if any, of the blood samples tested cna the patient with type b+ blood receive? explain why. 8. explain how you were able to use your knowledge of how different types of blood react with anti-a, anti-b, and anti rh antibodies to determine the blood types of the four samples. 9. if a person has type a blood, he or she would have antibodies for what blood type? 10. why is type o negative blood known as the universal donor? why is o positive not a universal donor?
The blood types of the four samples were determined on the basis of the anti-factor present. The condition of each of the blood samples are given below:
If the blood sample reacts with anti-a, then the blood sample must not have an antigen A.If the blood sample reacts with anti-b, then the blood sample must not have an antigen B. If the blood sample reacts with anti-Rh, then the blood sample must not have antigen Rh.Based on this, it may be concluded the result as:
Blood reacts with anti-A possess Blood group B.
Blood reacts with anti-B possess Blood group A.
Blood reacts with anti-A and anti-B possess Blood group O.
What do you mean by Rh-antigen?Rh-antigen may be defined as the transmembrane proteins that are expressed at the surface of erythrocytes.
If a person has Blood type A, he or she does not have anti-A antigen and possesses anti-B antibodies. This is because the anti-A antigen is a foreign substance for their body. Due to the presence of the Rh factor, the O-negative blood type is known as the universal donor because it does not have positive Rh to stimulate any abnormal reaction in the body, while O-positive has the Rh factor which stimulates or triggers various abnormal reactions.Therefore, it is well described above.

A cuticle occurs on the surface of organisms of many phyla and appears to be an advantageous feature. why have higher organisms not retained this structure?
While the cuticle has several advantages such as protection, they do not confer much advantage to larger eukaryotes. This is because of their limiting factor to growth (size). The cuticle would also restrict development of different skin structures such as fur. Additionally, while the cuticle provides leverage for muscular movements on arthropods, nematodes, and flatworms, it is not necessary for larger animals since the same function is rendered by the endoskeleton.

Through a process of _____, ADP is converted into ATP. dephosphorylation phosphorylation oxidation
Answer:
Phosphorylation
Explanation:
Phosphorylation is one of the metabolic stages of cellular respiration. It happens only in the presence of oxygen (aerobic beings), which is necessary to oxidize intermediate molecules and participate in reactions to form the ATP molecule and produce energy.
In the early stages of cellular respiration (glycolysis and Krebs cycle), some of the energy produced in the breakdown of compounds is stored in intermediate molecules, coenzymes such as NAD + and FAD +.
This oxidation energy of coenzymes is used for ATP synthesis. For this occurs phosphorylation of ADP, ie it receives phosphate groups. This is why this process is called Oxidative Phosphorylation.

Scientists observed a rock stratum with fossils. If mollusks evolved before arthropods, where will their fossils be found?
Answer:
Fossils of mollusks would be found in lower strata than that of arthropods
Explanation:
Fossils are found in different layers of sedimentary rocks. The fossils of organisms that evolved earlier are found in the lower strata while those evolved later are preserved as fossils in the upper strata. If mollusks evolved before arthropods, fossils of arthropods would be present in upper layers while those of mollusks would be found in deeper layers.
If mollusks evolved before arthropods, their fossils would typically be found in older rock strata, deeper in the Earth's crust, relative to the rock strata containing arthropod fossils.
In the geological principle known as the Law of Superposition, it is generally accepted that in undisturbed rock layers, the older rocks are found at lower depths, and the younger rocks are found closer to the surface. This principle is fundamental to the study of stratigraphy and the dating of fossils within rock layers.
So, if scientists observe a rock stratum with fossils and they know that mollusks evolved before arthropods, they would expect to find mollusk fossils in rock layers that are deeper (older) than the rock layers containing arthropod fossils. This stratigraphic order aligns with the concept of relative dating in geology, where the sequence of fossil appearances in rock layers can provide insights into the order of evolutionary events.

which type of wetland is constantly submerged in water and contains trees ?
A wetland refers to a different ecosystem, which is flooded by water, either seasonally or permanently, where the oxygen-free procedures exist. The main element, which separates wetlands from the other water bodies or landforms is the characteristic vegetation of aquatic plants, amended with the specific hydric soil.
Swamp refers to a wetland ecosystem featured by mineral soils with poor drainage and by plant species dominated by trees. The swamps are found all through the world, most usually in low-lying regions with poor drainage adjacent to rivers that supply the swamp with water. Some of the swamps develop from marshes, which gradually fill in, permitting woody shrubs and trees to develop.
