The rat's tail is an extension of the vertebral column that projects out the back side of the animal. The tail is a long cylinder consisting of three concentric layers. The innermost core of the tail is bone (vertebre).The bone is surrounded by a layer of tendons, and the tendons are surrounded by a layer of skin.he rat's tail is an extension of the vertebral column that projects out the back side of the animal.

Diseases transmitted by mosquitoes include: malaria, dengue, filariasis, West Nile virus, chikungunya, yellow fever, Japanese encephalitis, Saint Louis encephalitis, Western equine encephalitis, Eastern equine encephalitis, Venezuelan equine encephalitis, La Crosse encephalitis and Zika fever.osquito-borne diseases or mosquito-borne illness are disease caused by bacterial, viruses or parasites transmitted by mosquitoes.
(Answer #1). Vector borne diseases are illnesses caused by an infectious microbe that is transmitted to vertebrates by another animal, usually an arthropod. This second animal is called a vector for the disease.There are a large number of viral, bacterial and parasitic diseases that can be transmitted by insect vectors.The most common vectors are blood sucking insects such as mosquitoes, fleas, lice, biting flies, bugs, lice, helminthes and ticks.yme and bluetongue (spread by mosquitoes and ticks) are examples of devastating vector borne diseases that create havoc among the livestock population worldwide. Vectors typically become infected by a disease agent while feeding on infected vertebrates (like birds, rodents, other larger animals, or humans)..
