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.
Thus, the selected options are correct.
Yes indeed that the picture shows that the transport of the sodium and potassium ions. The picture shows a passive transport of sodium and potassium ions. And also we can see that the energy for the action of the pump is being released by the utilization of the ATP. Some are being moved and some are being brought back in.
Answer:
The color would be Pink
Explanation:
According to the question, the bacteria is positive for the enzyme urease and it's inoculated for 24 hours.
Urease broth is a differential medium that tests the ability of an organism to produce urease, that hydrolyzes urea to ammonia and carbon dioxide. The broth contains two pH buffers, urea, a very small amount of nutrients for the bacteria, and the pH indicator phenol red. Phenol red turns yellow in an acidic environment and fuchsia in an alkaline environment.
If the urea in the broth is degraded and ammonia is produced, an alkaline environment is created, and the media turns pink within 24 hours.
Many enterics can hydrolyze urea; but only a few can degrade urea rapidly. These are called “rapid urease-positive” organisms.
Urea broth is formulated to test for rapid urease-positive organisms. The restrictive amount of nutrients coupled with the use of pH buffers prevent all but rapid urease-positive organisms from producing enough ammonia to turn the phenol red pink.
D) crocodiles eating a buffalo... this is because the crocodile is a cold blooded animal therefore it doesn’t have to use the energy to maintain its body temperature.
