Question 1 of 5
1. Question
1 pointsThe term “sixth mass extinction/sixth extinction” is often mentioned in the news in the context of the discussion of
Correct
Explanation:
Researchers have described it as the “most serious environmental problem” since the loss of species will be permanent.
Even though only an estimated 2% of all of the species that ever lived are alive today, the absolute number of species is greater now than ever before.
The research claims that this extinction is human-caused and is more immediate than climate destruction.
Major drivers of mass extinction
Significantly, the study calls for a complete ban on wildlife trade as many of the species currently endangered or on the brink of extinction are being decimated by legal and illegal wildlife trade.
The current COVID-19 pandemic, while not fully understood, is also linked to the wildlife trade.
There is no doubt that there will be more pandemics if man continues destroying habitats and trading wildlife for own consumption as food and traditional medicines.Incorrect

Question 2 of 5
2. Question
1 pointsWhich of the following statement are correct about the Sun’S Corona?
1. The Sun’s corona is the outermost part of the Sun’s atmosphere.
2. Corona is hundreds of times hotter than the Sun’s surface.Select the correct answer using the code below:
Correct
The Sun’s corona is the outermost part of the Sun’s atmosphere. The corona is usually hidden by the bright light of the Sun’s surface. That makes it difficult to see without using special instruments. However, the corona can be viewed during a total solar eclipse.
Our Sun is surrounded by a jacket of gases called an atmosphere. The corona is the outermost part of the Sun’s atmosphere.The corona is usually hidden by the bright light of the Sun’s surface. That makes it difficult to see without using special instruments. However, the corona can be seen during a total solar eclipse.
The corona reaches extremely high temperatures. However, the corona is very dim. Why? The corona is about 10 million times less dense than the Sun’s surface. This low density makes the corona much less bright than the surface of the Sun.
The corona’s high temperatures are a bit of a mystery. Imagine that you’re sitting next to a campfire. It’s nice and warm. But when you walk away from the fire, you feel cooler. This is the opposite of what seems to happen on the Sun.Astronomers have been trying to solve this mystery for a long time. The corona is in the outer layer of the Sun’s atmosphere—far from its surface. Yet the corona is hundreds of times hotter than the Sun’s surface.
A NASA mission called IRIS may have provided one possible answer. The mission discovered packets of very hot material called “heat bombs” that travel from the Sun into the corona. In the corona, the heat bombs explode and release their energy as heat. But astronomers think that this is only one of many ways in which the corona is heated.
The surface of the Sun is covered in magnetic fields. This is the force that makes magnets stick to metal, like the door of your refrigerator.The Sun’s magnetic fields affect charged particles in the corona to form beautiful features. These include streamers, loops, and plumes. We can view these features in detail with special telescopes.
