An argumentative essay is a type of essay that presents a clear and well-reasoned argument in support of a specific position or viewpoint. A compare and contrast argumentative essay, on the other hand, is a type of essay that compares and contrasts two or more ideas, concepts, or arguments in order to evaluate their similarities and differences.
One key difference between argumentative and compare and contrast essays is the focus of the essay. While an argumentative essay presents a single argument or position and attempts to persuade the reader to accept that argument as true, a compare and contrast essay presents multiple ideas or arguments and examines the ways in which they are similar or different. This means that the structure of a compare and contrast essay will typically be more balanced, as it will present both sides of the comparison in equal measure.
Another key difference between these two types of essays is the level of detail and analysis required. An argumentative essay will typically include more detailed analysis and evidence in support of the main argument, as the goal is to persuade the reader to accept that argument as true. A compare and contrast essay, on the other hand, may not require as much detail and analysis, as the main focus is simply on comparing and contrasting the two ideas or arguments being presented.
There are also some similarities between argumentative and compare and contrast essays. Both types of essays require the writer to present a clear and well-reasoned argument, and both types of essays may include the use of evidence and examples to support the argument being made. Additionally, both types of essays may require the writer to consider and address counterarguments or opposing viewpoints in order to strengthen their own argument.
In conclusion, while there are some similarities between argumentative and compare and contrast essays, there are also some key differences. An argumentative essay presents a single argument or position and attempts to persuade the reader to accept that argument as true, while a compare and contrast essay presents multiple ideas or arguments and examines the ways in which they are similar or different. Both types of essays require the writer to present a clear and well-reasoned argument, but the level of detail and analysis required may vary depending on the specific type of essay being written.
Lateral line system
Hearing is also influenced by the lateral line system, as can be found in HEARING AND LATERAL LINES. As the wave passes, it causes the molecules of the matter it moves through to oscillate either backwards and forwards, or up and down. Both, superficial and canal neuromasts use this method of electrical signal transduction. The supra-orbital protrudes along the surface of the eye and joins the infra-orbital canal from the back of the nasal capsule to the anterior. He found a distinct relationship between the pore canal system and the lateral line in Osteotraci. The lateral line consists of only one sensory structure, the neuromast, which is made up of hair cells and a cupula. Some variations in the pattern of the lateral line canals and the arrangement of the neuromast organs are observed in bony fish.

By being able to sense this reflected wave, a fish can avoid bumping into things — such as the glass of a fish tank — even when all its other senses are inoperable. A gelatin-like substance called cupula is secreted by neuromast cells and thrown into the water. A supra-temporal or occipital canal is transversely connected to the lateral line canal near the head. The cupula is created by a gel-like media, which is secreted by non-receptor cells of the neuromast. Introduction - relevance LOS calculation problems Research and methodology The way ahead and implications.
Its wide variation can be noticed in teleost. Image Showing Lateral Line System Lateral Line Canal Neuromast cells are usually immersed in the cavity under the skin. In a minority of the units 2% , changing sphere location did not affect discharge rates but caused a change in phase coupling. The lateral line, one of the most complex vertebrate A radio frequency vibration travels through the body and reaches the brain, where it receives information such as nature and its location. It aids in the detection of motion in both water and prey.

In mature fish, the supra-orbital duct is above the eye, an infra-orbital duct is under the eye, a supra-temporal duct protrudes towards the back of the head and connects the lateral canal on each side. They form clusters in the center of the neuromast organ and are surrounded by many helper cells. The findings are discussed with respect to particle image velocimetry data of the water motions generated in the experiments. The helper cells are long and slender and are arranged around the sensory or receptor cells to form the circumference of the neuromast organ. Furthermore, they used gentamicin to disrupt the canal receptors and mechanical scraping of the neuromasts of the lateral line to check whether both the lines were used equally for orienting to prey. What Is The Function Of The Lateral Line In Sharks Photo by: blogspot The lateral line is a sense organ in sharks that allows them to detect changes in water pressure and vibration.

The lateral line canal of Chitala chitala does not connect the cephalic canal. In still water, individuals from both species responded to sound pressure levels SPLs between 92 and 109 dB SPL re 1 μPaRMS. In many fibers, the pattern of the response changed with speed and lateral distance of the moving object. FUNCTIONS AND ROLE OF THE LATERAL LINE Coombs, S. These waves are caused by anything that moves in the water and by the movement of the water itself. The neuromasts allow the fish to detect changes in water pressure and movement.

Neuromasts consist of modified epithelial cells, which show structural and functional similarity to the hair cells found in higher organisms reptiles, birds and mammals in the auditory and vestibular systems. Hearing: Inner ears are set in fluid-filled canals with sensory cells similar to the lateral line system. It extends along both sides of the body. Clear lateral line on bottom Canary SPIN. Our first task in understanding lateral lines is to look at the sorts of disturbances which may be of importance to fishes and to get a feel for the physics of how they are created and how they propagate in the aquatic environment. These representative fish show the position of fins in cartilaginous and bony fish. Due to the movement of water, any displacement of the cupuler is transported to hair-like growth.
The distribution of surface waves produced by insects determines how accurately an insect is detected. But in most cases it ends in a line. When vibrations are present, the fish can determine whether the disruption is caused by a similar fish or prey. Neuromasts are mechanoreceptors that are sensitive to water movements caused by external factors as well as animal swimming movements. From this starting point it would be nice to then explore the diversity of fish lateral line organs to show how sensory structures and central processing have been shaped by evolution to exploit the physical properties of.
Function and Role of the Lateral Line System in Fish
The waters of this planet are full of waves. Experiments have shown that chemical stimuli are absorbed through the sense of smell. Abyssal species such as Gulper eel and Ceratoid anglers do not have lateral line canals. Phylogeny I Chordate Origins 4. The sole neurons of the ELL are pyramidal cells, which project to the nucleus praeminentialis NP and the midbrain via the torus semicircularis TS. . Dynamic ocean currents also provide a lot of background noise which the fish needs to filter out so as to set a basal level of electromagnetic influx for navigation or prey detection.
There is a logical space between curved edges and unrestricted space. We also earn by displaying ads by Google AdSense. Sharks have a very sophisticated lateral line system that detects vibrations in the water and picks up prey. Its presence can be noticed by the groove-like line on the cheek of the fish. Any mechanical wave that passes through the water sets up reciprocal movements in the lymph fluid that surrounds the cupola. Image Showing Lateral Line Canal in Fishes In polypterus Chondrostei , the supra-orbital is attached to the infra-orbital at the tip of the trunk.
Despite the fact that sharks have functional olfactory organs, these smells are difficult for them to detect. We investigated how single units in the medial octavolateralis nucleus of the rainbow trout, Oncorhynchus mykiss, respond to a 50-Hz vibrating sphere in still and running water. Four types of units were distinguished. The mandibular branch extends to the tip of the lower jaw and joins the similar canals on the other side. The cells will produce a constant firing for as long as the stimulus is in fuelling the receptors.
