Consider the following statements regarding the Raccoon Roundworm:
It infects raccoons in parts of North America, Europe and Japan.
It causes severe disease only in animals.
Which of the statements given above is/are correct?
Correct
Answer: a
Explanation:
Recently, Europe is on alert after a new study revealed the raccoon roundworm, Baylisascaris procyonis, has firmly taken hold in wild raccoons across nine countries.
The raccoon roundworm (Baylisascaris procyonis) is the common large roundworm or ascarid found in the small intestinal tract of raccoons.
It infects raccoons in parts of North America, Europe and Japan, and less commonly in South America.
The parasite is indigenous to North America and emerging in Europe and Asia after the introduction of North American raccoons for the commercial fur trade in the early 20th century.
It can cause severe disease in humans and other animals.
Primary Hosts of Raccoon Roundworm: Racoons (Procyon lotor), Wild and domestic canids
Transmission & Life Cycle of Raccoon Roundworm:
Infection occurs through ingestion of infective eggs or infected paratenic hosts.
Eggs passed in racoon faeces are shed in the environment and take 2-4weeks to embryonate and become infective.
Many mammals and birds can become paratenic hosts after consuming the eggs.
Once infective eggs are ingested, the eggs hatch and larvae penetrate the intestinal wall where they can migrate to various tissues (liver, lungs, eyes, and brain), and infect the host.
Treatment and Control: Raccoons can be successfully treated with several anthelmintics to kill the adult worms.

With reference to Southern Ocean, consider the following:
It is located on the lower end of the Pacific, Atlantic, and Indian Ocean.
It is known for weak winds and high temperatures.
It was formed when Antarctica and South America drifted apart.
How many of the above statements are correct?
Correct
Answer: b
Explanation:
Recently, scientists have found the Southern Ocean mitigates global surface warming by taking up a large portion of the carbon released by human activities.
The Southern Ocean is also known as the Antarctic Ocean, is the fourth-largest ocean by surface area.
The International Hydrographic Organization describes the Southern Ocean as the World Ocean’s southernmost portion.
It is located on the lower end of the Pacific, Atlantic, and Indian Ocean, and includes the tributary seas around the Antarctic region.
It is known for its strong winds, intense storms, dramatic seasonal changes and cold temperatures.
It is dominated by the Antarctic Circumpolar Current (ACC) which is the longest, strongest, deepest-reaching current on earth.
Formation: It was formed around 34 million years ago when Antarctica and South America drifted apart, creating the Drake Passage.
Biodiversity: Powerful currents, cold temperatures and nutrient and oxygen-rich waters make the Southern Ocean one of the most productive marine ecosystems on Earth.
Role of Southern Ocean:
It plays an important role in the circulation of water around the globe.
It also plays a key role in regulating the earth’s climate through its currents, seasonal sea ice and by absorbing heat and carbon dioxide from the atmosphere.
