Student of class 9 had to present a seminar on 'dengue fever'.

Can you help me to Explain the above Points? GIVE DETAILS..​

Answer»

Explanation:1)-immediate cause of the diseaseDepends on the disease, obviously (or it should be obvious). Each has its own cause, cure, and prevention. There is no possible way to cure or treat all diseases.Infectious diseases are CAUSED by infectious agents: bacteria, viruses, fungi, protozoans, helminths, parasites, etc. (Ex: the COLD, athlete’s FOOT, AIDS, malaria, head lice). You prevent these by not being infected or by getting vaccinated against them. Cures and treatments vary.2)-defination of infectious diseaseA disease that is caused by a microorganism, such as a bacterium, virus, or protozoan, that is not normally FOUND in the body and is capable of causing infection. Some, but not all, infectious diseases are contagious, meaning they can spread from person to person.3)Pathogen causing Dengue fever.Dengue fever, also known as breakbone fever, is a mosquito-borne infection that can lead to a severe flu-like illness. It is caused by four different viruses and spread by AEDES mosquitoes.4)-Vector Responsible Foe dengueVector of dengue fever. Dengue infection is transmitted from one person to other by the bite of an infected female Aedes mosquito. Dengue fever (DF) is a viral infection caused by any of the four types of dengue virus ( DENV -1 to DENV-4).Thank you

The large intestine, also known as the large bowel, is the last part of the gastrointestinal tract and of the digestive system in vertebrates.

The large Intestine is like an upside down U.DetailsSystemDigestive systemArterySuperior mesenteric, inferior mesenteric and iliac arteriesVeinSuperior and inferior mesenteric veinLymphInferior mesenteric lymph nodesIdentifiersLatinColon or intestinum crassumMeSHD007420TAA05.7.01.001FMA7201Anatomical terminology[edit on Wikidata]The colon[2] is the largest portion of the large intestine, so many mentions of the large intestine and colon overlap in meaning whenever precision is not the focus. Most sources define the large intestine as the combination of the cecum, colon, rectum, and anal canal.[3][4] Some other sources exclude the anal canal.[5][6][7]In HUMANS, the large intestine begins in the right iliac region of the pelvis, just at or below the waist, where it is joined to the end of the small intestine at the cecum, via the ileocecal valve. It then continues as the colon ASCENDING the abdomen, across the width of the ABDOMINAL cavity as the transverse colon, and then descending to the rectum and its endpoint at the anal canal.[8] Overall, in humans, the large intestine is about 1.5 metres (5 ft) long, which is about one-fifth of the whole length of the gastrointestinal tract.[9]

During the propagation of a nerve impulse, the action potential results from the movement of O K+ ions from extracellular fluid to intracellular fluidO Nations from intracellular fluid to extracellular fluidKions from intracellular fluid to extracellular fluidNations from extracellular fluid to intracellular fluid​

Answer»

Na+ ions from extracellular fluid to INTRACELLULAR fluidExplanation:Action potential in a nerve is formed DUE to opening of Na + channels of the axonal membrane which results in movement of Na + ions inside the axonal cytoplasm.During resting state the axonal membrane is NEARLY impermeable to Na + ions and more permeable to K+ ions.So in the cytoplasm there is K+ concentration and in the external fluid there is Na+ ion concentration.When stimulus is applied then the Na+ ions move inside the AXON generating action potential .I HOPE THIS IS HELPFULTHANKS
