Answer:
b) x: fin
y: lateral line
z: swim bladder
Explanation:
The <u>dorsal fin</u> is found in the dorsal region of the fish body. Depending on the species, there can be one or two dorsal fins. Membranous structures and bony or cartilaginous ratios compose the fins. One of the main functions is to stabilize the body in water, providing equilibrium. When the dorsal fin is erect, it acts as a keel, helping the fish not to turn aside. Fishes also use these fins as protection because the cartilaginous or bony ratios act as spines. The animal uses these spines to defend itself from predators. The morphological variety of dorsal fins in the different species is used in taxonomy.
The <u>Lateral Line</u> is a system or sensory organ composed of special receptors called neuromasts, which can be found all along the lateral region of the animal. The lateral line perceives information from the environment, such as light, sound, or water movement, among others. These signs are translated into nervous messages. The lateral line is useful to detect prey, predators, other animals moving, objects, etcetera. It is significant for intraspecific interaction, especially during swimming motions in schools. The lateral line receives perturbations of short distance, generated by other living beings or by objects. Some studies confirm that the lateral line is also sensitive to chemical stimuli.
The<u> swim bladder</u> is a neumatic sac-like structure filled with gases coming from the blood. Its main function is to allow neutral floating and let the animal in suspension at any depth, with no need for muscular effort. The animal can regulate the size of the bladder. This organ can be found in most pelagic fishes, while the benthonic ones or the ones that actively swim lack it.
Answer: Kidney and lungs
When body pH become acidosis or alkalosis the first two organs that will be influenced is kidney and lungs. The body pH can alter your breathing frequency as carbon dioxide is making the pH more acidic. Acidic pH will make your breath faster so you can dump carbon dioxide faster. Acidic pH will also make your urine more acidic since the excess Hydrogen is dumped into the urine.
Answer: Savanna
Explanation:
The Savanna is a biome located in Africa and characterized by a lot of grass and dispersed trees. The climatic conditions are warm all year round and the summers are wet.
The presence of so much vegetation makes it an ideal biome for large herbivores like elephants, giraffes and wildebeests. As a result of so many herbivores being there, there are lots of carnivores as well such as lions and cheetahs.
The correct answer is outer electrons. These are sometimes called 'valence electrons', and they are responsible for the element's properties and how it forms bonds. For example, elements in Column 2 are likely to form ionic bonds with elements in Column 16. This is because elements in Column 2 have 2 outer electrons, while elements in Column 16 have 6 outer electrons. If the element in Column 2 gives its 2 electrons to the element in Column 16, then the former will be stable because the energy level underneath will be complete, and the latter will be stable because it will have a complete outer energy level with 8 electrons.
Hope this helps!
