There are many differeces between chondrichthyes and osteichthyes.
Chondrichthyes means "cartilaginous fishses", in fact their skeleton is made up of cartilage, while osteichthyes, which means "osseous fishes", have an osseous skeleton, but there are other differences: chondrychthyes have many branchial fessures, different reproduction, lack of swim bladder, and many others.
Ratfish belong to the subclass Holocephali, whereas most other chondrichthyes, such as sharks and rays, belong to the subclass Elasmobranchii. The main differences include the ratfish having a single gill opening, tooth plates for feeding, and a venomous spine on the dorsal fin, in contrast to the multiple gill openings, teeth, and lack of venomous spines in other chondrichthyes.

The morphological concept of species defines species based on physical characteristics, such as appearance and structure. In contrast, the biological concept of species defines species based on reproductive isolation - individuals that can interbreed and produce viable offspring are considered to be of the same species.
How to design a table comapare and contrast the characteristic of 5-7 different culutral group norm and values.
Binary and ternary forms rely on the repetition and contrast of two or three distinct sections, respectively, to create their structures. The sections in binary form are typically labeled as A and B, while ternary forms are often labeled as A, B, and A'. This repetition and contrast of sections give these musical forms their characteristic shapes and coherence.
One important characteristic of a leaf that can help identify it as a monocot is parallel venation, where the veins run parallel to each other along the length of the leaf. This is in contrast to dicots, where the veins form a branching network.
It is numerical information about some characteristic. By contrast, qualitative data might be something like the colour of your eyes, or the name of your maths teacher.
The difference in the same trait between two subjects refers to the variation or contrast in that specific characteristic when comparing the two subjects.
A CT scan that is repeated a certain number of times in the same examination period is said to be multiphasic (bi-phasic, tri-phasic, quadra-phasic). The interest is in observing a change in a parameter as a function of time. The main reason is to show the effect of intravenous contrast on CT attenuation, say pre contrast, and at one, three and five minutes post injection. By observing increased CT attenuation ( aka enhancement), or lack thereof, and it's temporal and morphological characteristics, radiologists infer the probable diagnosis. The same can be said of pre and post contrast studies using other contrast agents or routes of administration (e.g. pre and post contrast fistulography).
they are hypodense typically though can have a varied appearance. They can be diagnosed definitvely with a contrast enhacned CT or MR due to a characteristic enhancement pattern. They are a benign lesion.
Yes, you can determine the arrangement of the micoorganism such as chain, random, or spiral as the simple staining allows you to obtained a distinctive contrast between background and its organisms being observed.
Positive staining allows the bacteria to be directly stained and visualized under a microscope, which helps in studying their size, shape, and arrangement. It also provides valuable information about the cell wall structure and composition. Negative staining, on the other hand, allows the visualization of bacteria that are otherwise difficult to stain due to their thin or delicate cell walls. It provides better contrast and allows for the observation of fine morphological details of the bacteria.
