Question 2 of 5
2. Question
With reference to ‘Wolbachia’, consider the following statements
Statement 1- Wolbachia is a genus of bacteria that is present naturally in many of the insects
Statement 2- Wolbachia helps to reduce dengue, Zika and other mosquito transmitted diseases.
Which one of the following is correct in respect of the above statements?
Correct
Solution (a)
Statement Analysis:
About the Wolbachia:
- Wolbachia are extremely common bacteria that occur naturally in 50 per cent of insect species, including some mosquitoes, fruit flies, moths, dragonflies and butterflies.
- Wolbachia is safe for humans and the environment. Independent risk analyses indicate that the release of Wolbachia mosquitoes poses negligible risk to humans and the environment.
- Wolbachia lives inside insect cells and is passed from one generation to the next through an insect’s eggs. Aedes aegypti mosquitoes don’t normally carry Wolbachia, however many other mosquitoes do.
How our Wolbachia method works
- We discovered that when Aedes aegypti mosquitoes carry Wolbachia, the bacteria compete with viruses like dengue, Zika, chikungunya and yellow fever.
- This makes it harder for viruses to reproduce inside the mosquitoes. And the mosquitoes are much less likely to spread viruses from person to person.
- This means that when Aedes aegypti mosquitoes carry natural Wolbachia bacteria, the transmission of viruses like dengue, Zika, chikungunya and yellow fever is reduced.
- So, at the World Mosquito Program, we breed Wolbachia mosquitoes. Then, in partnership with local communities, we release them into areas affected by mosquito-borne diseases.
- Which means less risk of disease in communities where Wolbachia is established in the local mosquito population.

Question 3 of 5
3. Question
With reference to ‘Trojan asteroids’ consider the following statements
- They are asteroids that orbit with Jupiter around the Sun.
- NASA’s Lucy mission will is the first ever mission to visit these primitive asteroids.
Select the INCORRECT statement(s)
Correct
Solution (d)
Statement 1 Statement 2 Correct Correct Jupiter Trojan asteroids are remnants of our early solar system are trapped on stable orbits associated with – but not close to – the giant planet Jupiter. Trojan asteroids orbit in two “swarms” that lead and follow Jupiter in its orbit around the Sun and are thought to be comparable in number to the objects in the main asteroid belt between the orbits of Mars and Jupiter.
Lucy over its 12-year mission, Lucy will explore a record-breaking number of asteroids: it will by two (plus a newly discovered satellite) in the belt of asteroids that circle the Sun between the orbits of Mars and Jupiter, and then eight Trojans, which includes five asteroid targets and the satellites of three of those. Lucy also will fly by Earth three times to get a push from its gravity, making it the first spacecraft to return to the vicinity of Earth from the outer solar system.
