Explanation:
Answer:
The correct answer will be-
1 .Arbovirus is an arthropod-borne virus
2. An arbovirus is maintained in nature through biological transmission
Explanation:
An arbovirus is a group of the virus which spreads in nature especially infect human from the infected insects (Arthropods). The most common arthropods spreading the disease caused by the virus is the mosquitoes and few ticks, gnats and fleas.
The viruses are maintained in nature through biological transmission between the vertebrate hosts by blood-sucking arthropods like mosquitoes.

The following statements apply:
1. Salt is not chemically bonded to water.
2. The ratio of salt to water may vary.
3. Salt and water retain their own chemical properties.
The solution formed by dissolving salt in water is an example of a mixture, it is a physical change and no new substance is formed. The salt and the water are not chemically bonded and salt can easily be recovered from the water by mean of evaporation. Any amount of salt can be dissolved in the water and each of the component, that is, salt and water still retain their individual chemical properties.
