This question is incomplete. The question gives a choice between four skulls: A, B, C and D. The skulls are compared in a table for: Cranium/face area ratio, face angle and foramen magnum ratio.
The cranium/face area ratio relates to the size of the cranium relative to the rest of the skull, and we would expect this ratio to be fairly large for a human. The face angle relates to human faces in relation to primate faces, which are less protruded forwards (i.e., we have relatively flat faces), and the foramen magnum is the hole in the base of the skull through which the spinal column connects to the skull. In bipeds, we would expect this hole to be fairly equally distant from the back of the skull to the front of the skull, so this ratio would be closer to 1. Based on this information and the ratios given in the table, I would say that skull B is most likely a human skull.
Undigested food will be diffused from the surface of skin and reproductive cells come out of the mouth in aurelia.
Explanation:
The gastro vascular system in aurelia helps remove carbon dioxide and waste material from aurelia as there is no specialised excretory system. The waste material is diffused out through general body surface.
Aurelia are dioceous which means sexes are separate. Four gonads of either sex lie radially on the floor of gastric pouches. The gametes when ripened gets shed in the stomach from gonads and comes out of the mouth.
The spermatozoa shed by the mouth in seawater gets carried to the body of female by mouth. The fertilization takes place in gastric pouches.
<span>Because if we only classify animals by morphology, many animals have the same describable traits and physical structures.
Genes helped taxonomy better classify and aggregate animals.
Molecular genetics is scientific study of composition of genes. This field is a subcategory of biology and heredity which is responsible for unearthing and delving the anatomy and physiology of the genes. </span>This field helps us to understand and find evidence in the compounds, substances and elements found and synthesized in our genes and what contains in our nucleic acides –RNA and DNA –framework of our chromosomes. <span>And also the origin and history of how genes came to be. These are codes and like-signals that makes us who we are in a macro-perspective.<span>
